The primary function of this guide is to acquaint the user with the spec i fi c-
a tions, basic wiring and confi guration of the MDrive17 Mi crostep ping. The full
prod uct man u al and IMS Motor Interface GUI (for quick and easy parameter
setup) are avail able on the IMS Product CD or may be down load ed from the
IMS web site at www.imshome.com.

Please observe the following when handling, connecting and using your
MDrive17. Failure to observe these points may result in damage to the
product. All warranty and disclaimer information are located in the full

Logic level cables must not run parallel to power cables. This will introduce
noise and make the system un re li able.
Logic level cables must be shielded to reduce the risk of EMI induced
noise. The shield must be grounded at the signal source to AC ground.
The opposite end of the shield must not be connected which allows it to
fl oat and act as a drain.
The supply to the driver must be a twisted pair. If more than one driver is
being connected, run separate leads to each driver.

A char ac ter is tic of all motors is back EMF. Back EMF is a source
of current that can push the output of a power supply beyond the
maximum operating voltage of the driver. As a result, damage to
the stepper driver could occur over a period of time. Care should
be taken so that the back EMF does not exceed the maximum input
voltage rating of the MDrive17.

for the user to wire com mu ni ca tions. Included in
this cable is built-in logic level shifting circuitry to
ac com mo date the 3.3v ports on some PC's
This cable plugs in easily to con nect a stan-
dard DB-25 PC Parallel/SPI (Serial Peripheral
Interface) port to the 10 pin pin-header (P2)
