The DC link is pre-charged. Check:Check: - phase L3 for short-circuit or ground fault (-X2:W2 - including motor) - that CU is correctly inserted And look at Testing the IGBT Best regards, Hristo Mihalev

ooo Posts: 24 Rating: (0)	has beeen solved by replace 2 igbt but still showing o010 is that danger ?? also when i power on the motor but still in stand still the current is 750 and by running it decrease to 250 is that high starting current drive 6SE7138-6HG62-3BAO-Z TNX

Regarding the Starting current, this can be up to 6 times the running current (even with an inverter) Graeme Attachment r001 Drive Status Display.pdf (373 Downloads)

ooo Posts: 24 Rating: (0)	TNX Graeme but sometimes we leave the motor in stand still state and the motor deliver 750AMP all the time like 30min is that danger for IGBT and if yes any way to avoide that Regards

Graeme Platinum Expert Joined: 6/4/2008 Last visit: 8/5/2025 Posts: 1518 Rating: (327)	Hi, I don't know your motor details, is 750Amps the magnetising current (P103)? If there is actually 750Amps flowing into the motor, then there will be a problem after a while, because the motor is being heated and can potentially burn out. I don't believe that the IGBT's should be in any danger. Did you megger the motor after your problem? Regards, Graeme

I think when you stop the motor, you are only switching the setpoint to ZERO but run command is still there. Please check what is the status in stand still condition? is it o14 or o09. If it is o14, the above assumption is correct. Also, in this condition the motor shaft will appear like locked, you can't move it freely by hand even in decoupled condition. This is of course dangerous for the motor, particularly if the motor is self cooled,not force cooled. Hope it helps. Best regards

ooo Posts: 24 Rating: (0)	Dear, the status is o009 and once i puton the drive it shows 0000 and motor is locked whatever there is load or not as the motor in brake mode. the motor is forced cooling is that dangerous for the drive also or not specially the motor can withstand this current Regrads
