Motors with Black, Green, Red, and Blue wires

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 wire for counter-clockwise rotation when increasing position, reverse the red and blue wires.

Motors with Orange, Green, Yellow, and Red wires

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 wire for counter-clockwise rotation when increasing position, reverse the yellow and red wires.

Note: Make sure to unplug the power cord from the 1063 before switching wires around.
