Fig. 6-77 Overload protection setting for motor
Unit place: Motor protection mode
0: Disabled
The drive has no overload protection for the load motor (This function shall be selected carefully)
1: Common motor (with low speed compensation)
Because the heat dissipation of the common motor at low speed will be degraded, the corresponding
electronic thermal protection value shall be properly adjusted. Low speed compensation means to lower
the motor overload protection threshold for the motor with the running frequency lower than 30Hz.
2: Variable-frequency motor (without low speed compensation)
Because the heat dissipation of the special motor for drive is not affected by the rotating speed, it does
not need the protection value adjustment for low-speed operation.
Tens place: Overload pre-alarm detection selection
0: The overload detection works during the operation of the drive
1: The overload detection works only when the drive runs at constant speed.
Hundreds place: Overload pre-alarm action selection
0: The drive generates an alarm and continues operating when the overload detection is enabled, and the
operation panel will display AL.oL1 or AL.oL2 according to the setting of the hundreds place.
1: The drive will activate protection action and coast to stop when the overload detection is enabled, and
the operation panel will display Er.oL1 or Er.oL2 according to the setting of the hundreds place.
Thousands place: Overload detection level selection
0: The detection level relative to the motor rated current (Alarm code AL.oL2 and fault code Er.oL2)
1: The detection level relative to the drive rated current (Alarm code AL.oL1 and fault code Er.oL1)
