Just replace the five phase stepper motor with CNC lathe why reversal, did not move over the line, just plug the air outlet, open the electrical cabinet can see there are five wires on the drive circuit, because it is X to XA XB XC XD, respectively, XE is the wiring problem, ask an expert to point! Urgent
Loose or what, it is possible to control the port output signal is wrong, should be on these two possible ~!
Stepper motor connected to the drive signal line, one of which is the control direction, low level in one direction is in another direction, may be connected to the direction of the drive line that is a problem
Stepper motor operation is driven by the drive pulse, you should first determine the driver does not send a pulse, the driver's monitoring parameters should have this parameter inside, monitor it on the line.
