This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers on the Connection & Compatibility tab.

Motor Controllers

This motor must be controlled by a stepper motor controller. The following table shows how to connect the motor wires to the board connectors to produce a clockwise rotation in the stepper motor when increasing position.

To connect the motor to a bipolar motor controller, leave out the red wires.

Note: Make sure to unplug the power cord from the controller board before switching wires around.
