0: no protection. There is nomotor overloading protection characteristic (caution to use),and
thereby the inverter has no protection to the overloaded motor.
1: normalmotor (with low speed compensation).As generalmotor has a poor heat emission at
low speed, the relevant electronic thermal protection should be regulated properly.The low speed
compensation characteristic herementioned is to switch down the overloading protection
threshold for themotor with an operation frequency lower than 30 Hz.
2:Variable frequencymotor (without lowspeed compensation).As the heat emission of
special variable frequency motor is not affected by speed, it is not required to regulate the
protection value for lowspeed operation.
