Is this a new fault, or has it been intermittent from new? If the drive occasionally overvoltages, then it's possible that the motor is regenerating i.e. during deceleration and the drive cannot dissipate the excess power. To protect the hardware, the drive trips. With only an SDP, you will struggle to resolve this issue, you need at the very least, a BOP, or better the free software: Starter and a PC connection kit to diagnose the drive. Regards, Graeme

The Micromaster is the most reliable component for operating the brake. 3/ Also consider the ramp down time, has this been reduced? 4/ Has the mass of the system been increased? Note. If you do not have a keypad available, diagnosis for this problem will be difficult. Do you have a PC available with the STARTER software diagnosis tool installed?

No i don't have a keypad Its not mechanical brake This just start to happens this week Even if the motor is not running The motor is working fine and it's got this error in random times Did u watched my video?

It may appear that the supply is ok, using a meter, do you have a means of looking at the supply waveform? Sorry about this, but it needs some test equipment to diagnose what is causing this fault.
