Guide is to aquaint the user with the specifications, basic wiring
and configuration of the IM483 Microstepping Driver. The full
product 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.
Notes And Warnings
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

Controlling Microstep Resolution
The number of Microsteps per step is selected by the DIP switch
(SW1). The table below lists the standard resolution values and
the appropriate switch settings.
IM483 Current Adjust Resistor Values
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! 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
maintain 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).
Adjustable Output Current/Current Reduction
NOTE: Keep the resistor leads as
short as possible to minimize the
amount of noise coupled to the
IM483 Driver.
