P5.00
Motor overload protection mode selection
Range: 0,1
0
This parameter defines the protection mode when overload or overheat occurs.
0: Inverter locks the output. When overload or overheat occurs, inverter will lock output and the motor will free stop.
1: Disabled. Motor has no overload protection. (Be careful to use)
P5.01
Motor overload protection coefficient
Range: 20(%) ~120(%)
100(%)
This parmeter is used to set sensitivity of thermal relay protection for inverter load motor. When the output current value of
load motor can not match the rated current of the inverter, the motor can be thermal protected, as shown in Fig.4-30.
Use the following coefficient to calculate.
[P5.01] = × 100
