variastor board in TSU gets damaged when motor gets earth in multi drive system
We have ACS800 drives.
Whenever a motor gets earth from number of motors connected to an inverter the variastor board installed at TSU input gets blown.
I am unable to find any specific reason for the same.
Can you please guide me?
