Frequently asked questions
How do I wire the 4-lead cable?
This is a 4-lead bipolar motor with two coils. Connect one coil to A+ and A- and the other to B+ and B- on the driver. Identify each coil with a multimeter, since the two wires of one coil show continuity with each other.
Is the cable long enough for a typical machine?
The listing specifies a 1 m cable. Plan your driver placement so the cable reaches the motor without strain, and keep motor wires away from high-current power lines to reduce noise.
