QUICK REFERENCE
WARNING! The IM483 Driver components are sensitive to
Electrostatic Discharge (ESD). All handling should be done at
an ESD protected workstation.
WARNING! Hazardous Voltage Levels may be present if you
are using an open frame power supply to power the IM483
Driver.
WARNING! Ensure that the Power Supply output voltage does
not exceed the maximum input voltage of the IM483 Driver.
WARNING! Do not operate the IM483 Driver without a Cur-
rent Adjustment Resistor!
A resistor MUST be placed between the Current Adjust Input
(Pin 2 on P2) and ground (Pin 3 on P2) to keep the IM483
Driver and/or motor in a safe operating range.

24Step Clock Input
A positive going edge on this input advances the motor
one increment. The size of the increment is dependent
upon the settings of the resolution select switch SW1.
36Direction Input
This input is used to change the direction of the motor.
Physical direction also depends upon the connection of
the motor windings.
48Opto Supply
This +5 VDC input is used to supply power to the
isolated logic inputs. A higher voltage may be used, but
care must be taken to limit the current through the
opto-coupler.
510 Enable/Disable
This input is used to enable/disable the output section
of the driver. When in a Logic HIGH state (open), the
outputs are enabled. However, this input does not
inhibit the step clock, therefore, the outputs will update
by the number of clock pulses (if any) applied to the
driver while it was disabled.
612 Reset Input
When LOW, this input will reset the driver (phase
outputs will disable). When released, the driver will be
at its initial state (Phase A OFF, Phase B ON).
714 Fault Output This output indicates that a short circuit condition has
occurred. This output is active LOW.
816, 26 On-Full-Step Output
This open collector output indicates when the driver is
positioned at full step. This output can be used to
count the number of full steps the motor has moved,
regardless of the number of microsteps in between.
This output is active LOW.
21 Step Clock Output Non-isolated step clock output follows step input.
22 Direction Output Non-isolated direction output follows direction input.
23 Resolution Select 0 Microstep Resolution Select 0 input.
24 Resolution Select 2 Microstep Resolution Select 2 input.
25 Resolution Select 1 Microstep Resolution Select 1 input.
27 Ground Non-isolated ground. Common with power ground.

Reduction Adjust
Phase Current Reduction Adjustment Input. A resistor
connected between this pin and pin 2 will
proportionately reduce the current in both motor
windings approximately 0.5 seconds after the last
positive edge of the step clock input. The amount of
current reduced will depend upon the value of the
resistor used.
2Current
Adjustment
Phase Current Adjustment. A resistor is connected
between this pin and P2:3 (GND) to adjust the
maximum phase current in the motor. A resistor
MUST be connected to this input or the IM483 WILL
latch into fault.
3GND Power Ground. The ground, or return, of the power
supply is connected here.

Adjustable Output Current/Current Reduction
WARNING! Do not operate the IM483 Driver without a Current
Adjustment Resistor!
A 1/8Watt or higher, 1% resistor MUST be placed between the Current
Adjust Input (Pin 2 on Connector P2) and ground (Pin 3 on Connector P2) to
keep the IM483 Driver and/or motor in a safe operating range.
In addition, the output current may be reduced to the level needed to main-
tain motor holding torque by means of a 1/8watt or higher, 1% resistor
connected between the Reduction Adjust Input (Pin 1 on Connector P2) and
Current Adjust Input (Pin 2 on Connector P2).

Connecting And Using The Fault Output
The IM483 has an open collector fault output located on P1:7. This output is
non-isolated and has the ability of sustaining maximum driver voltage. It can
sink a maximum of 25mA, which is sufficient to drive an LED or a small relay.
This output is active when in a LOW state. The following conditions will cause
this output to become active:
1] Phase-to-phase short circuit.
2] Phase-to-ground short circuit.
3] Phase over-current condition.
When the fault output becomes active, it disables the driver outputs and
latches in this condition. It can only be cleared by toggling the reset input
LOW, or by powering OFF then powering ON the drive.

WARNING! The maximum +48 VDC Input Voltage of the IM483
includes motor back EMF, power supply ripple and high line.
WARNING! DO NOT connect or disconnect power leads or motor leads
when power is applied! Disconnect the AC power side to power down the
DC power supply.
For battery operated systems, conditioning measures should be taken to
prevent device damage caused by in-rush current draws, transient arcs
and high voltage spikes.
