These circuit protection values are the maximum values allowed by UL. See section 3) Wire Selection
for recommended wire and circuit protection values. Always follow all local and national electrical codes
when selecting circuit protection.
Separate fuses/breakers can be used for the control circuit. Install two fuses or a double pole breaker if
the control power will be using two phases of a 3-phase system. Due to inrush, each drive control circuit
should have separate circuit protection (don’t supply two drives with one breaker).

(11) Quick Start Guide
This section will show how to safely and quickly start up a SureServo2 (SS2) drive. Wiring and starting
up the drive should only be performed by a qualified professional. High voltage levels are in use.
Commissioning is quicker and easier using the drive configuration software SV2-PRO, but the entire
start-up procedure can be accomplished with the keypad (detailed here). For further information and
more complete startup instructions, please download the SureServo2 User Manual (SS2 UM) from
www.automationdirect.com. Be sure to visit www.automationdirect.com/videos for helpful videos covering
SureServo2 commissioning, programming, and operation.
Preliminary Wiring
To safely and quickly start up a SureServo2 (SS2) drive, several different types of wiring need to be
verified first. Until this wiring and functionality is verified, it is highly recommended to NOT connect main
incoming power (R,S,T) or connect the load to the motor shaft.
1. Connect the ground wires to the screws at the bottom of the drive. Connect the incoming
ground to one screw and connect the motor ground to the other screw. (The motor ground
wire is in the motor cable SV2C-Pxxx-xxxx.)
2. Connect the wiring for L1C and L2C (single phase 100-120VAC or 200-230VAC). This is
control power and should be continuously available (not disconnected with E-stop, etc.).
3. Connect an appropriate safety circuit to CN10. See the wiring diagram elsewhere in this
document or the SureServo2 User Manual. Although the CN10 connector comes pre-wired
with an STO bypass, it is strongly recommended to wire a safety relay to connect STO_A to
/STO_A and to connect STO_B to /STO_B.
4. Connect the motor encoder cable (SV2C-Exxx-xxxx) to the motor and to CN2 of the drive.
5. Connect the appropriate 24VDC input devices to DI1-DI10. Pay close attention to these
Digital Input (DI) definitions. Their default (out-of-the-box) configurations are listed below.
DI1 = Servo On input (wired normally open)
DI5 = Alarm Reset (wired normally open)
DI6 and DI7 = Overtravel inputs. Inputs are wired normally closed (in a fail-safe manner).
If the application is rotary and has no overtravel inputs, these inputs can be temporarily
wired to DC common (0 volts) or disabled thru programming (procedure shown below).
DI8 =Override (temporary Motor Stop input wired normally closed). NOTE: The STO input
(CN10) is separate from the Override (temporary Motor Stop input wired normally closed)
input DI8.

Apply Control Power and Reset to Factory Defaults
Once the preliminary wiring previously described is complete, control power can be applied to the servo.
Apply 110VAC or 220VAC power to L1C and L2C (the actual connector on small drives may be labeled
“L1” and “L2”); and apply 24VDC to the I/O (CN1 connector).
To ensure that the drive has all default settings, reset the drive. To do this, enter a value of 10 into
P2.008. On the drive’s keypad:
[These are the general instructions on how to set any Parameter address value]
1. Press M to enter Parameter Mode. (Press M until
you see a parameter address that begins with P,
like P0.000.)
2. Press ◄ to advance to the P2 group
3. Press ▲ or ▼ to advance to P2.008
4. Press S to enter P2.008 and see the current value
5. Press ▲ or ▼ to change the value to 10
6. Press S to set the value.
7. The drive will display SAVED, BUSY, then DONE.
Cycle power to the drive. The drive will now
contain all factory default settings.
Clear the Alarms
The drive will power up with alarms. The most common alarms are listed below with the most common
solutions. For more detailed information and all possible alarm codes, search for the alarm code (ALxxx)
in the SS2 UM.
Display
Alarm Name
Solution (see the UM for more details)
AL500
STO Enabled
Enable the safety circuit to connect the STO signals (CN10). When the
safety circuit is enabled, this alarm can be cleared. Reset with DI5
Alarm Reset. For temporary testing without a load attached to the
motor, the supplied jumpers on the CN10 connector can bypass the
STO feature.
AL501
AL502
AL503
STO Errors
These alarms occur when the STO inputs are not simultaneously
active/inactive. Ensure proper wiring and activation of the safety circuit.
Reset by cycling power to the drive.
AL003
Undervoltage
This alarm occurs when the main motor power (R,S,T) is not present
and the Servo On input (DI1) is ON. At this point of commissioning,
ensure that R,S, and T do NOT have power and that DI1 is OFF.
Reset this alarm with DI5 Alarm Reset.
AL011
Encoder error
Ensure the encoder is connected. Verify the wiring on CN2. Ensure the
motor ground and drive ground are properly connected. Reset by
cycling drive power.
AL013
Motor Override
Ensure that DI8 Motor Override is ON (DI8 is configured Normally
Closed as default). ON = current flowing = no fault.
AL014
AL015
Overtravel
Limit
Ensure that DI6 and DI7 are ON or redefine the inputs (see below).
These inputs are defined Normally Closed as default. ON = current
flowing = no fault.
Change the Digital Input Definition
If the application does not call for Overtravel limits, the definitions of DI6 and DI7 can be changed so that
alarms AL014 and AL015 are not active. To disable DI6 and DI7 by changing parameters through the
keypad, perform the following keystrokes:
1. Press M to enter Parameter Mode. (Press M until you
see a parameter address that begins with P, like
P0.000.)
2. Press ◄ to advance to the P2 group
3. Press ▲ or ▼ to advance to P2.015 (DI6 functional
planning)
4. Press S to enter P2.015 and see the current value
(default = 022 = Negative overtravel)
5. Press ▲ or ▼ to change the value to 000 to disable
the input
Note: ◄ moves the cursor left one digit (required for
some parameter entry)
6. Press S to set the value.
7. Repeat the procedure to disable P2.016 (DI7) if desired.

NOTE: Setting the least two digits of P2.010 – P2.037 to 00 disables the input.
The third digit signifies Normally Open or Normally Closed.
Input Definitions with 1xx are Normally Open. DI is ON when current is flowing thru the terminals.
Definitions with 0xx are Normally Closed. DI is ON when current is NOT flowing thru the terminals.
(It is recommended to set disabled inputs to 100, so the logic states are OFF when not energized.)
Verify Encoder Feedback
On the keypad, press M to cycle the display off of Parameter addresses (P2.015, etc.) or any active
alarms (AL500, etc.). The display will now show Drive Status. Press ▲ or ▼ until Fb.PUU is displayed.
After 1 second, the drive will display the Feedback Pulses in User Units. Rotate the shaft manually
clockwise. The display should increment from 0-99,999 for one motor rotation. Decimal points beside the
4th and 5th digits indicate a negative position. This is a quick indication of which side of absolute zero the
motor feedback is on. If an encoder alarm or unexpected feedback is seen, check all encoder cabling
from the drive’s CN2 to the motor. Check for loose connections or crossed wiring. See the UM for more
help.
Verify Digital Inputs
Set P0.002 to 39 to display the DI status (in hex format) on the drive’s LED display. As long as energizing
the input does not trigger an alarm, the LED display will report the Digital Input status in hex. If an input
does trigger an alarm (example: if DI8 is set for Motor Override and the input is ON), AL.xxx overrides the
DI display (AL013 = Motor Override). Press M to cycle the LED back to the DI status display.
If the Digital Input is defined as Normally Closed (the function code is 0xx), the input will be considered
active (ON) if there is no current flowing thru the terminal. Note: inputs defined as 000 are disabled, but
are considered ON (Normally Closed) if there is no current flowing thru the terminals. To redefine the
inputs, see Change the Digital Input Definition section above.
If this is the only input
that is ON

Verify Digital Outputs (DOs)
The Digital Outputs can be forced ON without requiring the corresponding DO function to be active. To
put the outputs into Diagnostic Mode, set P2.008 to the value 406. Select the Digital Outputs to force ON
and OFF by setting the hex value in P4.006. Each DO is forced ON by the corresponding bit set in
P4.006. (DO1 = bit 0, DO2 = bit 1, etc.). Press ◄ to move the cursor left one digit. Press S to set (apply)
the force to the outputs.

Once DO testing/verification is complete, exit DO Diagnostic Mode by cycling control power to the drive.
Connect Motor Power and Spin the Motor (w/o load)
NOTE: It is highly recommended to not connect the motor to the load before verifying proper motor
operation. When first spinning the motor, the shaft should not be connected to anything.
1. Connect a motor power cable to the motor and drive (Ground=green, U=red, V=white,
W=black).
2. Re-verify incoming control power (L1C, L2C), DI/DO wiring (including 24VDC power), and STO
wiring (CN10).
3. Ensure that the Servo ON input (DI1) is not ON.
4. If using a brake motor, connect 24VDC to the brake wires to release the brake. Polarity is not
important.
5. Connect incoming main power to the drive (Ground, R,S,T).
6. If any alarms are present, correct the alarms (refer to the explanation above for common
alarms, refer to the UM for more information).
The drive can be jogged from the keypad to verify operation.
7. Enable the Servo ON input with DI1. The motor should lock into position.
8. Refer back to Step #4. It is embarrassing if you forget to release the brake.
9. Set the desired Jog Speed in P4.005 (or press S to accept the default 20rpm in P4.005):
The display will now display -JOG-
NOTE: If the display shows SV-On, enable Servo ON with DI1 and repeat Step 9
10. Use ▲ and ▼ to jog the motor forward and reverse.
Press M to change speed.
Cycle the drive’s control power to exit Jog Mode.
NOTE: the display will not annunciate alarms while in Jog Mode.
Once the motor successfully jogs, the motor, feedback, and drive have been shown to be properly
installed. The system can now be programmed and commissioned along with the control system.
There are tables at the beginning of Parameters Chapter 8 that detail the most common parameters
used for the different drive control modes:
PT Mode: Position control – Terminals (high speed pulse input commands)
PR mode: Position control – Registers (point-to-point moves using internal registers for setpoints)
This mode includes point to point moves, registration, and camming
S Modes: Speed/Velocity control
S = analog input speed command
Sz = internal speed registers that include a zero-speed setting
T modes: Torque control
T = analog input torque command
Tz = internal torque registers that include a zero-torque setting
Firmware Upgrade
Occasionally, there will be new servo drive firmware to add new features or correct problems. Go to
http://www.automationdirect.com and search for your servo drive part number. On that part number's
item page you will find a link for the latest SureServo2 firmware. Compare the website’s current firmware
version to P0.000 (firmware version) and P5.000 (firmware sub-version) in the servo drive. If the versions
match, your drive has the latest firmware. If the online version is higher than P0.000, download the
firmware file from automationdirect.com. Next, open SureServo2 Pro software and connect to the drive.
Then select "Burn" from the pull-down menus to update your drive's firmware. Please see the
SureServo2 Pro help file for detailed instructions and more information.
