Micromaster 440

Hi,

We have one micromaster 440 drive which is running smoothly for long time now there are some issues coming

when the motor rpm coming down 1500 one of the phase current is exceeding and further down motor trips.. what could be the reason and how to troubleshoot? 

Regards

sandy

what is the alarm or the fault in the drive.check the motor windings. check the cable of the motor

Hi,

F00052 is now coming and motor winding and cable already checked and its good but now immediately it is tripping and showing F0052

Hi Sandy,

Fault F0052 is power stack fault. Try to reload your backup parameters and run it without load(motor) else you need to change your drive.
