Leadshine Stepper Drives Quick Start Guide – First Edition – 11/04/2019
DM542E, DM556E, DM860E, DMA860E
The DM542E and DM556E drives are capable of pulse and
direction operation, with auto-motor config on power up.
The DM860E and DMA860E drives possess the same capabilities
but can also do CW and CCW pulse operation. The main
difference between these models are output current range to
the motor and supply voltage.

Connecting Devices to the Drive
4-lead motors are the easiest to connect, and the speed – torque of the motor depends on winding
inductance. To determine the output current of the drive, multiply the nameplate motor phase current
by 1.4 to determine the peak output current. If the motor runs too hot then multiply by 1.2 instead. For
6-lead and 8-lead motor wiring information, please refer to the drive User Manual.
The drives are designed to operate within a specific voltage input (see specifications table). When
selecting a power supply, choose a power supply with an output range within the minimum and
maximum of the drive and be sure to leave room for power supply fluctuation and motor back-EMF.
The DM542E, DM556E, DM860E, and DMA860E drives can be connected for either sinking or sourcing
signals. Wire the connections to the motor, power supply, and controller according to the diagrams on
