Part 1: Hardware Specifications
Note: A
characteristic 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 +75 VDC.
WARNING!
The MDrive has
components which
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 your MDrive product.
WARNING! Ensure
that the power
supply output
voltage does not
exceed the maximum input
voltage of the MDrive34Plus
(+75 VDC).

Parameter setup cable MD-CC300-000 (USB to SPI) or equivalent and adapter MD-ADP-1723C for
pluggable interface.
Product CD or Internet access to www.imshome.com.
Control Device for Step/Direction.
+5 to +24 VDC optocoupler supply.
An Unregulated +12 to +75 VDC Power Supply.
Basic Tools: Wire Cutters / Strippers / Screwdriver.
18 AWG Wire for Power Supply, 22-28 AWG Wire for Logic Connections (Not Required for Flying
Leads version).
A PC with Windows XP SP2.
Connecting the Power Supply
Using the 18 AWG wire, connect the DC
output of the power supply to the +V input
of the MDrive34Plus
Connect the power supply ground to Power
Ground (P3:2 - Wire Crimp, Black Flying
Lead).
See Figure GS.1.
