Out of curiousity, are stepper motor failures common with cctv domes, just I have loads of steppers (none of that spec) from printers, very old computer stuff and gambling machines, and never actually come across a broken stepper motor yet. Its always been the driver circuitry or wiring, or sensor circuitry/controller.

If cctv stuff is breaking steppers on a regular basis, then something is wrong somewhere... They should be very hard to break in normal operation.

your right...........I swapped the second motor with the other and the problem remained.....PTZ internal is bad or has a problem. I'll call it spare parts from now on...........

thanks for listening.
