Hi everyone,
I have an issue on 200 HP variable torque VFD driving a 250 HP fan. the issue is the phase B IGBT inverter that goes to overtemperature that causes a VFD tripping. at the beginning we thought the VFD was faulty then we replaced with a new one. the same problem appeared in the second one. so now we think we are getting this problem from the motor. could you please guide me what procedures should we follow to solve this issue?. by the way, we are getting an RPM metter to perform a power quality analysis.
Thank you for inputs
