Disabled
The motor overload protective function is disabled. The motor is exposed to potential
damage due to overheating. A thermal relay is suggested to be installed between the AC
drive and the motor.

The AC drive judges whether the motor is overloaded according
to the inverse time-lag curve of the motor overload protection.
PA.01
Motor overload protection
gain
0.20~10.00
1.00
The inverse time-lag curve of the motor overload protection is:
220% x PA.01 x rated motor current (if the load remains at this value for one minute, the AC
drive reports motor overload fault), or
150% x PA.01 x rated motor current (if the load remains at this value for 60 minutes, the AC
drive reports motor overload fault).
NOTE:
Set PA.01 properly based on the actual overload capacity. If
the value of PA.01 is set too large, damage to the motor may
result because the motor overheats but the AC drive does not
report the alarm.
PA.02
Motor overload warning coefficient Setting Range
：
50%~100%

This function is used to give a warning signal to the control system via DO before motor
overload protection. This parameter is used to determine the percentage, at which pre-
