SECTION 3 STEP MOTOR DRIVER

When configuring the motor in a series configuration

(connected from end to end with the center tap floating)

multiply the per Phase (or unipolar) current rating by

0.7. Use this result to determine the current adjustment

pot setting.

4 Lead Motors

Use the specified series motor current to determine the current adjustment

resistor value. Four-lead motors are usually rated with their appropriate

series current, as opposed to the Phase Current which is the rating for 6 and 8

lead motors.

8 Lead Motors

Series Connection: When configuring the motor windings in

series, multiply the per Phase (or unipolar) current rating by

0.7. Use this result to determine the current adjustment pot

setting.

Parallel Connection: When configuring the motor windings in

parallel, multiply the per Phase (or unipolar) current rating by 1.4.

Use this result to determine the current adjustment Output Current

pot setting.

WARNING! Step motors will run hot even when configured correctly. Damage may occur to the motor if a

higher than specified current is used. Most specified motor currents are maximum values. Care should be

taken to not exceed these ratings.

Note: A fault light on the DPD60401indicates a short occurred or the over temperature condition setting the

fault light. Powering down momentarily will clear the fault.
