Section 1
Introduction
The IM483
The IM483 is a high performance, yet low cost microstepping
driver that utilizes surface
mount ASIC technology. The
IM483 is small, easy to interface
and use, yet powerful enough
to handle the most demanding
applications.
The IM483 has 14 built-in mic-
rostep resolutions (both binary
and decimal). The resolution can
be changed at any time without
the need to reset the driver. This
feature allows the user to rapidly
move long distances, yet precisely position the motor at the end of travel
without the expense of high performance controllers.
With the development of proprietary and patented circuits, ripple current
has been minimized to reduce motor heating common with other de-
signs, allowing the use of low inductance motors to improve high speed
performance and system efciency.
The IM483, because of its small size and low cost, can be used to
increase accuracy and smoothness in systems using higher step angle
motors. In many instances mechanical gearing can be replaced with mic-
rostepping, reducing cost and eliminating potential maintenance.
Available as options for the IM483 are a variety of connector styles, a heat
sink and thermal pad and a dual clock input version of the IM483. If in-
telligent and/or closed loop control is needed the IM483 is available with
on-board indexer (IM483I) and indexer/encoder (IM483IE) versions.
The IM483 was developed to provide designers with affordable, state-of-the-art
technology for the competitive edge needed in today’s market.

The Product Manual
The main sections of this manual address the standard IM483 driver,
which come with 8 position screw terminals as a connection medium.
The different connector, input options and accessories are covered in
detail in the appendices.
The indexer (IM483I) and indexer/encoder (IM483IE) versions of the
IM483 are not covered in this document, as they have their own manual.
The Product Manual
The IM483 product manual in its electronic format may be downloaded
from the IMS website at http://www.imshome.com. This version includes
a Bookmark feature that allows the reader to link from a Bookmarked
Topic in the Table of Contents to a full description of
that feature’s attributes and functions. You can also
select a Topic directly from the Table of Contents Pages.
Topics with a Bookmark function are further identiable
because the cursor changes from a normal pointer to a
“nger” pointer when placed over the word.

WARNING! The IM483 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 using an
open frame power supply to power the IM483.
WARNING! Ensure that the power supply output voltage does not
exceed the maximum input voltage of the IM483.
