IMS IM483H Plus User manual

Electrical Specifications
HYBRID MICROSTEPPING DRIVERS
WARNING! The IM483H Plus/IM805H Plus 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 IM483H Plus/IM805H Plus!
WARNING! Ensure that the power supply output voltage does not exceed the maxi-
mum input voltage of the IM483H Plus/IM805H Plus!
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.
WARNING! Do not apply power to the IM483H Plus/IM805H Plus without proper heat
sinking or cooling! The TI-22 Isolating Thermal Pad MUST BE used between the IM483H
Plus/IM805H Plus and the heat sink! The maximum rear plate temperature of the IM483H
Plus/IM805H Plus is 85°C.
IM483H Plus & IM805H Plus
Quick Reference/Installation Guide
The primary function of this guide is to acquaint the user with the specifications,
basic wiring and configuration of the IM483H Plus/IM805H Plus Hybrid Micro-
stepping Drivers. The full product manual is available in Acrobat PDF format on the
IMS Product CD. 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 IM483H
Plus/IM805H Plus 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
and should be referenced for more information.
Thermal Specifications
Ambient Temperature ....................................................................0° to +50° C
Storage Temperature ................................................................-40° to +125° C
Maximum Plate Temperature ..................................................................+85° C
Soldering the IM483H Plus/IM805H Plus to a PC
Board
The IM483H Plus and IM805H Plus hybrids are designed to be soldered directly to
a PC board. Recommended soldering practices:
Max. Soldering Temp..............................................................................315°C
Max. Soldering Time............................................................................. 10 sec.
TI-22 Thermal Pad – It is ESSENTIAL that the TI-22 IsolatingThermal Pad included with
the IM483H Plus/IM805H Plus be placed between the rear plate of the hybrid and the
heat sink. Use of this pad will improve thermal ow between the driver and the heat sink
as well as isolate the electrical signals present on the rear plate.
For More Information:
See the complete IM483H Plus/IM805H Plus Product Manual
on the IMS Product CD or at www.imshome.com
NOTE: If upgrading your system from an IM483H Plus to an IM805H Plus, or
vice-versa, please note that the Phase A and Phase /A output pins (Pins 7 & 9) are
reversed. This will cause the motor to turn in the opposite direction. To correct this
condition swap the motor wires on Phase A.

Pin Assignment
W A R N I N G! When interfacing the FAULT IN/RESET input, an open collector, tri-state
output or blocking diode is REQUIRED or damage may occur. Please see the IM483H
