Connecting Devices to the DM322E 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 DM322E drive can be connected for either sinking or differential control signals. Wire the
connections to the motor, power supply, and controller according to the diagrams on the next page:
