The primary function of IM483 Quick Reference and Installation
Guide is to acquaint the user with the specifi cations, basic wiring
and confi guration of the IM483 Microstepping Driver. The full prod-
uct manual is available in Acrobat PDF format on the IMS Product
CD, shipped with the product. It also may be downloaded from the
IMS web site at http://www.imshome.com.
N o t e s A n d W a r n i n g s
Please observe the following when handling, connecting and using
your IM483 driver. Failure to observe these points may result in
damage to the drive. All warranty and disclaimer information is
located in the full product manual on the CD and should be refer-
enced for more information.
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.

Function
Microstep Resolution Select 3 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.
This input is used to change the direction of the motor.
Physical direction also depends upon the connection of
the motor windings.
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.
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.
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).
This output indicates that a short circuit condition has
occurred. This output is active LOW.
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.
Non-isolated step clock output follows step input.
Non-isolated direction output follows direction input.
Microstep Resolution Select 0 input.
Microstep Resolution Select 2 input.
Microstep Resolution Select 1 input.
Non-isolated ground. Common with power ground.
