0:No protection
1: Common motor (with low speed compensation).
Because the heat-releasing effect of the common
motors will be weakened, the corresponding
electric heat protection will be adjusted properly.
The low speed compensation characteristic
mentioned here means reducing the threshold of
the overload protection of the motor whose running
frequency is below 30Hz.
2: Variable frequency motor (without low speed
compensation) Because the heat-releasing effect
of the specific motors won’t be impacted by the
rotation speed, it is not necessary to adjust the
protection value during low-speed running.

Motor 1
overload
protection
coefficient
Times of motor overload M = Iout/(In*K)
In is the rated current of the motor, Iout is the
output current of the inverter and K is the motor
protection coefficient.
So, the bigger the value of K is, the smaller the
value of M is. When M =116%, the fault will be
reported after 1 hour, when M =200%, the fault will
be reported after 1 minute, when M>=400%, the
fault will be reported instantly.
