Product Description:
The function is tracking the actual speed from the speed reference. It can only be used for hoists with tachometer or pulse encoder.
In case it finds an abnormal state, it sets a fault flag, gives code 91, and can not be reset by OFF like Overspeed faults. It opens DATX110 DO8 (emergency stop) depending of the selection of parameter 10.30
USE_OVSP. The function is developed to make an early stop with the working brakes of the high speed
side in case there is an electrical fault, and avoid to stress the emergency brakes and rest of the drive system as far as possible.
The function can as well be used for hoists without any emergency brakes, and in that case it can emergency trip the whole crane .
