Frequency Converter Protection Function

(1) Automatically correct the abnormal state after detection, such as overcurrent stall prevention, regenerative overvoltage stall prevention.

(2) After detecting the abnormality, block the PWM control signal of power semiconductor device to make the motor stop automatically. Such as over current cut off, regeneration over voltage cut off, semiconductor cooling fan overheating and instantaneous power failure protection.
