Hi
Before I start, I did not specify or supply this....
I have a inverter rated motor (50Hz = 100% speed). The motor drives an agitator, and the motor is fitted with a thermistor.Due to the 'hygenic' requirments there is no cooling fan on the motor.
Apparently the user has to run the drive at 100Hz (200% speed) to reach the desired agitator RPM and the 'drive is tripping out'
I am going to visit this site next week to take a look at it.
My immediate thinking is that the motor is incorrectly specified, or needs a gearbox (or different gearbox). The motor must be running hot and the thermistor is tripping.
I woould never exceed about 150% on inverter applications as a rule of thumb so am after general opinions really
