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!

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.
