Intelligent Motion Systems MForce PowerDrive Plus MForce Series Microstepping PowerDrive - Manual (Page 7)

1-1 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 the MForce
PowerDrive.
WARNING! The MForce
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 MForce product.
WARNING! Ensure that
the power supply output
voltage does not exceed
the maximum input
voltage of the MForce product that
you are using!
Getting Started
Microstepping MForce PowerDrive
Before You Begin
The Getting Started Section is designed to help quickly connect and begin using your Microstepping MForce
PowerDrive. The following examples will help you get a motor turning for the first time and introduce you to
the basic settings of the drive.
Tools and Equipment Required
 Microstepping MForce PowerDrive Unit (MFM)
 A NEMA 23 or 34 Size Stepping Motor
 Control Device for Step/Direction
 +5 to +24 VDC Optocoupler Supply (if using sinking output type)

An Unregulated +12 to +48VDC Power Supply
 Basic Tools: Wire Cutters / Strippers / Screwdriver
 Wire for Power Supply (18 AWG) and Motor (16 AWG)
 22 AWG Wire for Logic Connections
Connecting the Power Supply
Using the recommended wire, connect the DC output of the power supply to the +V input of the connector
appropriate for your Microstepping MForce PowerDrive model.
Connect the power supply ground to the Power Ground pin appropriate for your Microstepping MForce
PowerDrive.
