Looking for BP stepper motor parallel wiring schematic with motor phase connections to Gecko 203V drives. Having trouble finding a straight forward diagram. Thank you !
The steppers have six wires, correct? There will be two phases, you need an ohm meter to find which wires are for which phase. There is a center tap plus each end wire on a coil (3 wires per coil) The two ends will have a higher resistance between them while the center tap should be roughly half the resistance. Find the two end wires, for each phase. Those are the 4 you will connect to the G203V. The center taps are not used with bipolar drives and should be insulated from all other wires.

Measure the resistances to find the correct wires. See attached.

If the motor has a name-plate rating of 7A or less you will get better performance (double) if you use the center-tap and one end wire compared to the end-wire to end-wire connection suggested here.

Found a diagram for bridgeport stepper wiring in parallel. I have not tested this but will update findings when retrofit is complete
