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 efficiency.
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.
