Frequency setting signal-10 ~ + 10, 0 ~ + 10, 4 ~ 20mA, high frequency pulse, PWM pulse
Protection functionOverload capacityG:60s-rated current x 150%;  3s-rated current x 200%; P:60s-rated current x 120%;  1s-rated current x 150%
Instantaneous overcurrent / short circuit protectionMore than 200% of the rated output current, automatically cut off the output
Overvoltage / undervoltage protectionWhen the bus DC voltage is too low (360V) or too high (800V), the motor stops freely (except braking)
Open phase protectionIn case of phase loss at the input or output end, the motor stops freely
Overheat protectionWhen the radiator temperature is 85 ºC, the motor will stop automatically; The temperature protection threshold 
can be set freely according to the ambient temperature
Motor protectionAnalog input can be connected with temperature sensor input (PT100, PT1000) to realize motor overheating protection
Stall protectionPrevent stall during acceleration or deceleration or operation (working current can be set)
Grounding protectionby current sensor
Instant stopThe load feedback energy compensates for the voltage reduction and maintains the continuous operation of the frequency 
converter in a short time
