Feb 11, 2018 - STEPPER MOTOR BASICS - 5 WIRES UNIPOLAR / BIPOLAR MOTOR example.The basics on how stepper motor, stepper controller,. May 17, 2018  I have a 5 phase stepper motor PK596-AE from oriental stepper motors and planning to use a driver with built in controller (CRD514-KD). The motor has 10 lead wires and the drives has 5. I figured out that the motor (bipolar-pentagon)-driver connection should be as shown below. Motor Driver Blue + Black = Blue Red + Brown = Red Orange + Purple.

I built a bunch of these to use with Linux EMC. I used this same circuit for all types of stepper motor dirvers in CNC's, eggbot's, Idle Air Control (IAC) Testers, digital meter movements etc. The TA8050P chips are capable of handling 30V at 1.5 amps per phase with built in overcurrent, overvoltage, and overtemperature protection.I also used the cheaper TA8080K chips which are 30V at 1a. There are different versions of the pic code for full and half step modes. Using a larger pin count chip it would be possible to add a select pin for step mode and even an enable pin.

I never really needed that since I build each board or a specific machine and know if I will need half or full step mode. The lack of enable has never really bothered me. I used the enable signal from the computer to control the motor supply. The PIC's are run from a separate 5v supply so they keep their logic active. I have also placed an auto lamp in series with the motor supply lead and used the enable line to shunt it with a relay.

I am told that multiple O.S. Windows pe to usb.

This keeps a low current through the motors when they are not enabled and acts as a brake. I want to try using a programmable supply and use the enable pin to raise the motor supply voltage providing the same effect without the glowing lamp. It just seems too complicated when I have so many 1156 bulbs on the shelf.
