Note: If "1" is selected for ±10V short circuit action. When a ±10V short circuit fault occurs and lasts, the
drive will automatically report Er.10v after the alarm operates for 15 minutes. When a 24V short circuit
fault occurs, the drive will report Er.24v immediately and stop no matter what 0 or 1 is selected for the
thousands place of P97.00.
P97.01 defines the protection action selections for input/output phase loss, external analog frequency /
torque command loss, motor over-temperature and analog input fault.
P97.02 defines the protection action selections for temperature sampling disconnection, under-voltage
fault, auto reset interval fault and fault locking.
Fig. 6-82 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
