Us2: Trip action threshold
Ts1: Delay time of alarm action
Ts2: Delay time of trip action

6.17 Short circuit protection

When the motor current exceeds the set value, the protector will switch circuit breaker or

alarm within the set time.The short circuit protection is divided into two stages: starting and
running. The protection parameters of the two stages can be set independently.

Note:
Imax: Maximum current
Is1: Threshold of short circuit alarm during starting stage
Is2: Threshold of short circuit alarm during operation
Is3: Threshold of short-circuit trip during starting stage
Is4: Threshold of short-circuit trip during operation
Ts1: Delay time of alarm action
Ts2: Delay time of trip action

6.18 Temperature protection

Temperature protection is based on the thermistor resistance embedded in the stator windings

or bearings of the motor.According to the type of thermistor selected, the protection logic is
different: when the thermistor is PTC, when the detected resistance value is greater than the set
value, the protector will trip or alarm within the set time;When the thermistor is NTC, when the
detected resistance value is less than the set value, the protector will trip or alarm within the set
time
