ALWAYS power down the driver before connecting or disconnecting a motor wire. Failure to do so will very probably fry the driver
For most common 5-wire unipolar motors;
With 6-wire unipolar motors;
Hook up the controller A+, A-, B+, and B- terminals to the phase leads (guess at the phases) and try to step slowly.
If the motor does not turn, try swapping one A wire with one B wire, you may have connected the motor phasing wrong. If you have the phasing wrong, the motor will tend to sit there and "wobble" or "buzz".
If the motor turns, but in the wrong direction, you only need to swap the two A wires with each other.
I have an older animatics 4 axis unipolar stepper controller and I would like to connect an 8 wire 2 phase Vexta stepper motor to it. The controller has output leads numbered 1-8 with no markings of A,-A,B,-B. Is there any way of testing the driver output leads to know which 8 leads of the motor (A,-A, A,-A, B,-B, B,-B) to connect to the driver leads 1-8?
James Newton replies: The only idea that comes to mind is to fire up the controller with a set of resistors connected from each output to ground. Then measure what the outputs do after each step pulse is applied. What resistor value to use? I have no idea.+
I have 4 axis Micro Step Motor drive with coil markings A,-A,B,-B. The 8 wire Stepper Motor has markings for Bi-Polar A,-A,-C,
C,B,-B,-D,D. How do I connect the 8 motor wires to the 4 post of the Driver Board ??
