INTRODUCING THE SD17060B
Applicable Units
This manual applies to all SD17060B drivers manufactured after December of 2008 as well as some
SD17060B drivers manufactured during December of 2008. This manual also applies to all SD17060B-03
and SD17060B-25 drivers. You will be able to determine the date of manufacture from the serial number on
the driver. Serial numbers for all AMCI drivers are formed from a date code and sequential number. The
serial number format is shown below.
For SD17060B Drives...
If your year of manufacture is 2009 or later, (digits 3 and 4 are “09” or greater), then this manual
applies.
If your month and year of manufacture is December of 2008, (digits 1 through 4 are “1208”), and the
sequential number is “0135” or greater, then this manual applies.
If your month and year of manufacture is December of 2008, (digits 1 through 4 are “1208”), and the
sequential number is less than “0135” then most of the information in this manual applies. The only
difference is that these older SD17060B drivers require external resistors for input signals greater than
5Vdc. Refer to Appendix A on page 18 for additional information.
If your month and year of manufacture is November of 2008 or earlier, (digits 1 through 4 are “1108”
or less), then most of the information in this manual applies. The only difference is that these older
SD17060B drivers require external resistors for input signals greater than 5Vdc. Refer to Appendix A
on page 18 for additional information.
For SD17060B-03 Drives...
The “-03” option was added in February of 2010. This manual applies to all SD17060B-03 units.
For SD17060B-25 Drives...
SD17060B-25 drivers have different resolution settings than the SD17060B and SD17060B-03. In
addition to this change, the SD17060B-25 will only accept 24Vdc input signals. The SD17060B-25
cannot be used in systems that have 5Vdc differential or 12Vdc single ended signals.
This manual is designed to get you up and running quickly using the SD17060B or
SD17060B-25 stepper drivers. As such, it assumes you have some basic knowl-
edge of stepper systems, such as the resolution you want run your motor at, and
the reasons why you’d want to use Idle Current Reduction and the reasons why
you wouldn’t. If these terms or ideas are new to you, we’re here to help. AMCI has
a lot of information on our website and we are adding more all the time. If you
can’t find what you’re looking for at http:///www.amci.com, send us an e-mail or
call us. We’re here to back you up with all of our knowledge and experience.

Applicable Units (continued)
For SD17060B-24 Drives...
As of January 2009, the SD17060B-24 has been phased out of production and replaced by the standard
SD17060B. The older SD17060B drivers required an external resistor when using a 24Vdc input signal and
the SD17060B-24 drivers had this resistor added internally. With this manual, the standard SD167060B driv-
ers have inputs that accept 5 to 24Vdc signals without the need for an external resistor and they replace the
SD17060B-24 in all applications. See Appendix Bon page 19 for more information.
The SD17060B, SD17060B-03 and SD17060B-25
The SD17060B, SD17060B-03, and SD17060B-25 micro-stepping drivers are part of the growing line of
motion control products from AMCI. They are designed for use with a variety of stepper motors including
AMCI’s size 23 through size 34 motors. The three drivers can be programmed to a maximum resolution of
50,800 steps per turn and output a motor current of 1.0 to 6.3ARMS that is programmable in 0.1ARMS incre-
ments.
SD17060B and SD17060B-03 digital inputs accept 5Vdc to 24Vdc without the need of an external cur-
rent limiting resistor
SD17060B-25 digital inputs will work with 24Vdc only
Common features of the three drivers include:
Inputs that accept 5Vdc to 24Vdc without the need of an external current limiting resistor
Anti-Resonance Circuitry
Back-EMF Protection Circuity
Programmable Idle Current Reduction
Programmable Current Loop Gain
Programmable Pulse Train Input (Step/Direction or CW/CCW)
Programmable Active State for the Disable Input
Most of the information in this manual applies to all three drivers and the “SD17060B” part number is used to
refer to all three. When giving information that only applies to the SD17060B-03 or SD17060B-25, the com-
plete part number, i.e. “SD17060B-25”, is used.
SD17060B-03
The SD17060B-03 differs from the other two drivers in the way it controls the Fault Output.
On all SD17060B units, (including the -03 and -25), the Fault Output conducts when the unit is operational,
and turns off when there is a fault. This way, a loss of power will appear as a fault.
On the SD17060B and SD17060B-25 units, the Fault Output will be off if the driver is disabled on power up.
On the SD17060B-03, if the driver is disabled on power up, the Fault Output will be on and stay on until the
drive is enabled. At this point, the SD17060B-03 runs its self checks and determines the proper state for the
Fault Output.
SD17060B-25
In addition to the 24Vdc digital inputs, the SD17060B-25 has different resolution settings than the other two
drivers. The table below shows the settings available on each driver with the differences highlighted.

Replacing an Older SD17060B
When replacing a SD17060B that was produced prior to December, 2008 with a unit that was produced after
December, 2008, you will have to remove any current limiting resistors if you had driven the inputs with 12
or 24Vdc. Refer to Appendix A, USING OLDER SD17060B DRIVES, on page 18.
Upgrading from the SD17060
The SD17060B replaces the AMCI SD17060 in all applications. The SD17060B has several advantages:
The SD17060B uses the latest power switching transistors for greater efficiency and fewer thermal
loses.
Greater efficiency and a thinner front panel means you can space the drivers closer together in an enclo-
sure.
The Disable Input on the SD17060B can be used to reset the driver. The SD17060 could only be reset
by cycling power to it.
The SD17060B has the same back panel mounting pattern, allowing you to quickly change between
units.
The Current Loop Gain now has an automatic setting that allows the SD17060B to determine the appro-
priate gain when the driver is powered up.
However, improvements sometimes require changes, and there are a few minor changes between the drivers.
The ±STEP/CW pins on the Indexer Connector are swapped. This change makes the SD17060B
indexer pinout the same as a majority of other drivers manufactured by AMCI.
The SD17060 required external resistors to use 12 Vdc or 24 Vdc inputs. These resistors are no longer
needed when using the SD17060B and they must be eliminated for proper operation. This statement
only applies to SD1760B drivers shipped during the second half of December, 2008 and later. See
Applicable Units on page 3to determine when your SD717060B driver was shipped.
The third harmonic switch settings on the SD17060 have been replaced with the following on the
SD17060B:
1) Disable Input Active State: Allows you to program the Disable Input to be active when volt-
age is applied to the input or active when voltage is removed. The default setting mimics the
behavior of the Disable Input on the SD17060.
2) Anti-Resonance Enable: The anti-resonance circuitry can be enabled or disabled.

MOUNTING THE SD17060B
Outline Drawing
There are two ways to mount the SD17060B.
The first method is with four #10-32 screws into its side panel.
The second method is by the mounting tabs. Mounting tabs are for #6 screws.
Minimum and maximum screw lengths should be observed to prevent a screw from
shorting to the PC Board.
There are airflow holes in the top and bottom of the enclosure. To ensure adequate convec-
tional airflow, the driver must be mounted in the orientation shown in the drawing.
Grounding
The SD17060B must be grounded for proper operation. The GND connection on the power connector is con-
nected to the SD17060B enclosure and is a sufficient grounding point for most applications. When mounted
the SD17060B on a surface that is electrically conductive and grounded, you should also take steps to ensure
that the two are electrically bonded together. If necessary, remove paint for the bolt mounting surfaces of the
panel to ensure adequate electrical bonding.
Airflow and Wiring Space
To ensure adequate airflow and wiring space, you need two inches (50 mm) of space above and below the
driver, one and one-half inches (37 mm) of space to the left and right of the driver, and one inch (25 mm) of
space in front of the driver. These dimensions are typical for convectional cooling. If you have an active
cooling system such as enclosure fans, you will be able to mount the drivers closer together.

SWITCH SETTINGS
The SD17060B is configured by DIP switches on the top of the driver. The factory default setting has all
switches in their off (0) position except for SB2-1. (CurrentLoop Gain = 1) All switch setting are latched.
You must cycle power to the driver before changes take effect.
Note on Idle Current Reduction
The SD17060B controls the
RMScurrentthroughthemotor.
Therefore it can momentarily
put 1.4 times the motor's rated
current through the windings
safely. If you choose a setting
of No Reduction, the
SD17060B will revert to peak
current control when the motor
is not turning. This feature pro-
tects the motor from damage.
You will not see a reduction in
holding torque.

SD17060B
SD17060B-25
You can program the Disable Input's
active state. When Active High, you
must apply power to the input to disable
the driver. When Active Low, you must
apply power to the input to enable the
driver. If you are not using the input, set
this switch to Active High and the driver
will operate as you expect. When the
Disable Input is active, the SD17060B
removes power from the motor and stops
accepting indexer pulses. Over-temp and
Over-current faults are cleared when the
driver transitions from a Disabled state.
Allows the SD17060B to compensate for
back-EMF generated by the motor. It
should be left enabled for most applica-
tions. Disable only if you are sure you do
not want this feature or under the advice of
AMCI tech support.
This setting allows you to compensate for 
variations in motor properties which will give you smoother motion and better positional
accuracy. See the Setting the Current Loop Gain section on page 14 for more information.
Self-Test mode is controlled by the switch SB4-1. If you change the state of this switch
while power is applied to the SD17060B, the driver will respond by rotating the attached
motor clockwise at 60 RPM with a resolution of 50,000 steps per turn. Note that changing
this switch does not alter the current supplied to the motor. All switch settings are read and
latched on power up. However, you must return this switch to its correct setting for normal
operation before cycling power or resetting the SD17060B.

CONNECTING YOUR CONTROLLER
I/O Connector
The I/O connector on the SD17060B accepts inputs from your indexer
as well as the Disable Input and Fault Output.
All SD17060B-03 drivers and SD17060B drivers sold after Decem-
ber, 2008, have inputs that accept 5Vdc differential signals and can
also be wired to accept single ended sinking or sourcing inputs of up
to 24Vdc without the need of an additional current limiting resistor.
SD17060B-25 units only have 24Vdc inputs. See Applicable Units
on page 3for information on determining when your unit was shipped
from the AMCI factory.
Input Wiring
All inputs on the SD17060B are low
voltage, low power signals. All wiring
should use shielded, twisted pair cable
such as Belden 9727 instrumentation
cable.
The shield of the cable should be
grounded at one end only, preferably at
the indexer or controller. Do not ground
the shields at the SD17060B. If you
must splice the cable, do not connect the
shields to ground of the junction box.
Indexer Inputs
These inputs can be programmed to
accept Step & Direction or CW/CCW
pulses. This setting is controlled by
SW1-1.
Disable Input
When active, the motor current is off
and the driver does not accept indexer
pulses. The active state of the Disable
Input is set by switch SB1-4.
RLD
An additional load resistor may be
required on some PLC outputs to
improve switching time. A symptom of
this problem is that the motor will begin
to run rough at high speeds. A 470 or
560 ohm resistor should be used. For
5V and 12V systems use a 1W resistor.
For 24V systems use a 2W resistor.
These power ratings assume that the out-
put can be normally on. For systems
where you are sure the output is always
normally off, the wattage ratings can be
cut in half.

Output Wiring
The ±Fault Output is an optically isolated transistor capable of driving a typical PLC input. The Fault Output
is normally on (conducts current) and turns off under the following conditions:
The Interlock jumper is missing on the motor connector
There is a short in the motor, either phase to phase or phase to ground
The heatsink temperature exceeds 90°C (195°F)
The driver is in its reset state and is not ready to accept pulses
Both ends of the output are uncommitted, so it can be wired as a sourcing or sinking output. The figure shows
a typical connection as a sourcing output.
RLIMIT
A resistor may be needed to limit the current through the Fault Output. The value, and power rating of the
resistor is dependent on the value of Vdc, the voltage drop across the input, and the current requirements of
the input.

CONNECTING YOUR MOTOR
Compatible Motors
The SD17060B will work with many different motors, including those not sold by AMCI. This section
assumes that you have already chosen your motor and you are looking for wiring information. No wire colors
are given because there is no single industry wide color coding standard for stepper motor wires. You must
refer back to your motor data sheets for this information.
AMCI offers several different stepper motors in sizes 23 and 34. Refer to our website, www.amci.com, for
additional information on these products.
Motor Wiring
The Interlock jumper is a safety
device that is needed for proper
operation. The SD17060B will not
power the motor without this jumper.
When the jumper is installed,
up to 170Vdc is present on the
connector. Do not use the Interlock
for anything other than its
intended use as a safety device.

POWER CONNECTOR AND INDICATOR LED’s
Power Connector
The SD17060B operates on 115Vac. If 230Vac is the only power available, consider using one
of the 230Vac drivers available from AMCI. Information on these drivers can be found on our
website, http://www.amci.com. If this is not an option, a step-down transformer must be
installed to power the SD17060B. The transformer must have a minimum power rating of 800
VA.
The SD17060B must be grounded for proper operation. Grounding is accomplished with the
GND pin on the power connector, and through proper bonding to the enclosure. Power con-
nections should be tight. Loose connections may lead to arcing which will heat the connector.
Phoenix Contact specifies a tightening torque of 4.4 to 5.4 lb-in (0.5 to 0.6 nM)
Indicator LED’s
The SD17060B has two indicator LED’s.
STEP/FAULT 
Green: Driver Operational
Flashing Green: Driver Operational, Receiving Pulses
Red: Driver Fault (The Over Temperature and Over Current faults can be cleared with the Disable
Input.)
1) Over Temperature Fault: The heatsink temperature exceeds 90°C (195°F)
2) Over Current Fault: Generally, a short exists somewhere in the system. This can be a short in the
motor or in the driver itself.
A)Phase–Phase Short:There is an electrical short between the two motor windings. The short
exists in the motor cable or in the motor itself.
B)Phase–Ground Short:One of the motor’s windings is shorted to earth ground. (The EARTH GND
terminal of the Motor Connector is used as the reference point.) The fault
can be in the motor cable or in the motor itself.
C)Back EMF:In applications with large motors and high deceleration rates, back-EMF generated by
the motor may also cause this fault.
3) Interlock Fault: The two Interlock Terminals on the motor connector are not connected with a short
jumper.
Flashing Red: Current Loop Gain AUTOID Error. There is a problem with the motor wiring or the
motor current is set to zero.
Flashing Red/Green @ 1Hz: Step Violation: The indexer sent step pulses to the SD17060B before the
driver was ready for them. The driver was disabled, in a fault condition, or had not completed its initial-
ization sequence on power up or reset. The stepper motor position will be invalid. The motor is not dis-
abled and can still be driven. While there is motion, the LED will flash at approximately 4 Hz.
CURRENT LOOP GAIN: This LED is also used when the Current Loop Gain is set to AutoID. (SB2:1-
5 all turned off) When set to AutoID, the driver will determine the parameters of the attached motor on
power up and will flash the Step/Fault LED green the number of times that the parameter should be set
to. Flashing red indicates a problem with the motor wiring or the motor current is set to zero. Further
information can be found in the next section of the manual, Verifying System Setup.

VERIFYING SYSTEM SETUP
Setting the Current Loop Gain
Setting the Current Loop Gain correctly allows you to maximize your motor’s performance. The SD17060B
takes into account the line voltage, output current and motor impedances when determining the optimum gain
for your system.
Assuming a stable line voltage of 115 Vac, the following gains should be used for AMCI motors. These gain
settings are averaged values based on a large sample of motors. Your system may benefit from increasing or
decreasing these settings. In general, increase the setting by one or two counts to improve high speed perfor-
mance or decrease the settings for quieter low speed operation.
If you are using a non-AMCI motor, use the following procedure to determine the correct gain for your sys-
tem. The SWITCH SETTINGS section on page 9 should be used to verify switch settings.
1) Turn off all of the switches in switch bank SB2. This configures the Current Loop Gain setting to its
“AutoID” value.
2) Verify that the motor current is set correctly. (Switch SB3-5 and switch bank SB4.)
3) Verify that the motor is attached to the driver.
4) Cycle power to the driver. The STEP/FAULT LED will begin to blink almost immediately. Count the
number of blinks. This number is what you should initially set the Current Loop Gain to.
5) Set the switches in SB2 to equal the number of times the STEP/FAULT LED blinked.
6) Cycle power to the SD17060B and verify motor operation using the System Checkout procedure on
the following page. If need be, adjust the Current Loop Gain settings up or down depending on your
application.
In some cases, the Current Loop Gain can be set to its AutoMode setting and the SD17060B will automati-
cally determine the proper gain on every power up or reset. This procedure is done in under two seconds.
The Current Loop Gain’s AutoMode setting, though convenient, should be used with caution.
Changes in the system while the gain is being measured, such as a change in line voltage, or
noise being injected into the motor cable, can force the drive to set the gain to an incorrect
value. This can lead to a system that appears to randomly fail when power is cycled to the
drive. AMCI strongly suggests using the above procedure to set the gain to a fixed value
whenever possible.

VERIFYING SYSTEM SETUP

System Checkout
1) Verify all wiring and grounding before applying power to the SD17060B. Make sure the rubber boots are
on the driver’s motor and power connectors.
2) Apply 115Vac power. With the motor attached, the power and status LED’s should come on green. A
problem exists if either LED does not light, or the Status LED is red. Remove power and refer to the
Troubleshooting section of this manual which begins on the following page.
3) Check for holding torque on the motor. If you have less then you expected, the most common causes are
improper motor current switch settings or having the Idle Current Reduction turned on.
4) The Self-Test feature of the SD17060B allows you to verify your motor wiring without an indexer. With
power applied to the driver, toggle the SB4-1 switch. The motor will begin to rotate clockwise at 60 RPM.
You must remove power from the driver to stop the rotation. If the motor rotates in the counter-clockwise
direction, swap the +B and –B connections. If the motor does not rotate at all, verify your current setting
and the motor’s wiring.
5) Have your indexer make a slow move in the clockwise direction for one turn. While the turn is in progress,
the STEP LED should blink. Verify that the motor rotated in the correct direction for one complete turn. If
you are using an optical encoder or other position feedback, verify that the indexer or controller is reading
it properly.
6) Repeat step 4 with a one turn move in the counter-clockwise direction. Again verify that the motor rotated
in the correct direction for one turn.
Any failures at steps 5 or 6 are usually caused by not setting the Pulse Train Input switch cor-
rectly or programming the wrong number of pulses in the indexer profile. If the motor rotates
in the wrong direction you can swap the +B and –B connections instead of altering your pro-
gramming.
7) If you are using the Disable Input, verify its operation with the motor stopped. Note that the motor will have
no holding torque while this input is active and the motor’s shaft will be free to rotate.
8) If you are using the Fault Output, verify that it is On (conducting). Remove power from the SD17060B,
disconnect the motor, and re-apply power. The STEP/FAULT LED should be red and the Fault Output
should be off (not conducting).
9) Remove power and re-attach the motor. Power the driver.
10) Consider altering the motor current or enabling the Idle Current Reduction if it is not already enabled.
Lowering the motor current or enabling Idle Current Reduction can greatly reduce motor heating.

TROUBLESHOOTING
Indexer Problems
Driver Problems
Symptom Solution
My indexer/PLC reports a fault
from the SD17060B when every-
thing seems fine.
Your logic may be reversed. On the SD17060B, the Fault Output is on
(conducts current) when the driver is working correctly and turns off (stops
current flow) when there is a fault with the driver. Therefore, losing power
to the driver appears as a fault. If you’re expecting the fault output to turn
on and conduct current when there is a fault, then your logic is reversed.
The motor is running faster/
slower than expected and/or the
distance traveled is farther/
shorter than expected.
Most likely a problem with the SD17060B’s Step Resolution setting or
the indexer’s programming. If the motor is running too fast, the Step
Resolution on the SD17060B is set lower than the indexer’s program-
mer assumed it would. If the motor is running slow, the Step Resolu-
tion is set higher than the indexer programmer assumed it would be.
Symptom Solution
Both LED’s are off, and the Fault
Output is active. (Not conduct-
ing) Power is applied to the
driver.
1) The AC line voltage may be too low. It must be greater than 85Vac
for the SD17060B to operate properly.
2) One or both of the 10A fuses may be blown. These fuses will not
blow under normal circumstances, so call AMCI for assistance.
Blown fuses may be a sign of serious installation problems.
Both LEDs are green, the Fault
Output is inactive, (conducting)
but the motor is not powered.
1) The ±Disable input may be active. The active state, (power applied
or power removed), is set by DIP switch SB1-4. This switch may be
set incorrectly.
2) The Idle Current Reduction may be set to its To 0% setting. With
this setting, current is removed from the motor if a directional pulse
is not received for one second.
The STEP/FAULT LED does
not blink when the indexer sends
pulses to the driver. The motor
does not turn.
1) Verify that your two directional inputs on the Indexer Connector are
not swapped or cross-wired.
2) If the inputs are wired as a sinking or sourcing instead of differential,
verify that they are wired correctly. If your indexer has sourcing out-
puts, then the inputs of the SD17060B must be wired as sinking
inputs and vice versa. Also note, if you are using an older
SD17060B-24, or an SD17060B-25, the outputs must be at 24Vdc.
3) If you are using a 24Vdc system and you are converting from an
older SD17060B to a newer SD17060B, you must remove the
external 3.9K resistors from your wiring. Refer to the Applicable
Units section on page 3to determine the age of you driver.
The STEP/FAULT LED is red. The driver is experiencing a fault condition. All faults are latched, so
power must be cycled to the driver or the Disable Input must be tog-
gled before the fault will clear.
1) Over Temp Fault. Is the driver very hot? It shuts down when its
internal temperature exceeds 90°C (195°F).
2) Interlock Fault. The motor is not plugged into the driver or a wire
jumper was not installed between the two Interlock pins on the
Motor Connector.
3) Short in Motor. Shut off the SD17060B and disconnect the motor.
Pull back the rubber boot and verify the following with an ohmmeter.
a) Open circuit from “A+” to “B+” pins. (Tests for short between
phases.)
b) Open circuit from “A+” to “Earth Ground” and “B+” to “Earth
Ground”. (Tests for short between phase and case.)
If any of these readings is not an open circuit, then check your wir-
ing. The most common cause of a short between phases is cross-
wiring the phases when wiring the connector. If you see a phase-to-
case short, make sure you don’t have a stray wire from the “B+” or
“A-” terminals hitting the Earth Ground terminal on the connector.

Motor Problems
As noted above, sometimes a problem that appears to be with the motor is actually a problem
with the indexer. The SD17060B has a Self-Test feature that allows you to verify motor opera-
tion without an indexer. With power applied to the driver, toggle the SB4-1 switch. The motor
will begin to rotate clockwise at 60 RPM. You must remove power to the driver to end the self
test.
Please remember to return SB4-1 to its original position before cycling power to the driver.
Symptom Solution
The motor has no holding
torque. 1) If the Step/Fault LED is red, then a problem exists with the driver or motor. Refer to Power Connector and Indicator LED’s on page 13
for information.
2) If the motor rotates when commanded but has no holding torque,
then your Idle Current Reduction switch is set to the To 0% setting.
This setting removes motor current when the driver is idle for more
than one second. There are other idle current reduction settings
available. See Switch Settings on page 9for more information.
3) The SD17060B ships with the motor current set to its minimum
value of 1.0 amp. It’s possible that it was not set for your applica-
tion. See Switch Settings starting on page 9for the proper switch
settings.
The SD17060B blinks its STEP/
FAULT LED green when pulses
are applied to the driver, but the
motor only emits a high pitch
noise. It does not rotate.
1) The acceleration or starting speed values may have been set too
high when the indexer was programmed. The motor may start to
accelerate and stall as the acceleration increases.
2) The Step Resolution may be set to a values lower than you are
expecting. For example, if the Step Resolution is set to 200 instead
of 400, the acceleration value is effectively doubled.
The motor only runs in one direc-
tion. This problem is usually caused by the directional pulse inputs. If your indexer is sending pulses in the CW/CCW format and the driver is con-
figured for the Step & Direction format, the motor will rotate counter-
clockwise when the driver receives CW pulses, and it will not rotate at
all when the driver receives CCW pulses. If the indexer is sending
pulses in the Step & Direction format and the driver is configured for
the CW/CCW format, the motor will only rotate clockwise, even when
the indexer is commanding a counter-clockwise move.
The motor runs backwards. (CW
instead of CCW and/or CCW
instead of CW)
1) One of the motor phases may be reversed. The “quick fix” is to
reverse the connections on the ±B windings.
2) There may be a problem with the directional inputs. Either they are
wired incorrectly or the format is wrong. Check wiring and see the
previous problem for more information on problems with format.
As its running speed increases,
the motor begins to run rough,
and eventually stops while
pulses are being applied.
1) If you are using single ended outputs for your pulse and direction
signals, you may have a problem with the outputs not switching fast
enough. See the note on the RLD Resistor in the Connecting Your
Indexer section on page 10.
2) You may have a problem with resonance in the system. Run the
system with the Anti-Resonance feature enabled and disabled to
see which give you better performance. The Anti-Resonance fea-
ture is set with SB1-5. See page 9for more information.
The motor runs erratically. 1) The motor is not correctly coupled to the load.
2) The deceleration rate is set to high and the inertia of the load is car-
rying the motor past the point where it is supposed to stop.
3) You are performing a slow move, (under 1 revolution/second) while
the Step Resolution is set to 200 or 400 steps/turn. To correct this
problem, try increasing the indexer’s starting speed parameter. Do
not increase the starting speed beyond your slowest running speed.
4) The motor current is set too low and the motor is unable to move
the load.
5) The motor is not correctly wired. Eight lead motors can be wired in
series or parallel. Series connection gives you more torque at lower
speeds and parallel connection gives you more torque at higher
speeds.

Applicable Units
This appendix applies to all SD17060B drivers manufactured prior to December of 2008 as well as some
SD17060B drivers manufactured during December of 2008. The inputs of these units were designed for use
with 5Vdc differential outputs and require external current limiting resistors when used with 12Vdc and
24Vdc input signals.
You will be able to determine the date of manufacture from the serial number on the driver. Serial numbers
for all AMCI drivers are formed from a date code and sequential number. The serial number format is shown
below.
For SD17060B Drives...
If your month and year of manufacture is December of 2008, (digits 1 through 4 are “1208”), and the
sequential number is less than “0135” then this appendix applies.
If your month and year of manufacture is November of 2008 or earlier, (digits 1 through 4 are “1108”
or less), then this appendix applies.
If you are replacing an SD17060 with an older SD17060B, then keep any current limiting
resistors you already have in the circuit. The only wiring change that you will have to make is
swapping the ±STEP/CW connections on the indexer connections.

USING OLDER SD17060B-24 DRIVERS
Applicable Units
This appendix applies to all SD17060B-24 drivers. The SD17060B-24 has internal current limiting resistors
on its inputs and can only be used in 24Vdc systems. The SD17060B-24 was phased out of production in
December of 2008 and replaced by the redesigned SD17060B.
Replacing a SD17060B-24
A SD17060B-24 can be replaced by a SD17060B without changes to the system as long as the SD17060B
was manufactured after December of 2008. If the SD17060B was manufactured prior to the second half of
December 2008, you will have to add current limiting resistors to the circuit before using the SD17060B. See
Appendix Aon the previous page for more information.
