gain
OV protection responds gain : It track and adjust while OV protection process. The frequency inverter adjusts the
frequency adding according to the bus voltage increasing rate and actual bus voltage. Increasing the respond gain can
improve the respond speed. But it makes the speed shake.

coefficients
While motor overload for long time, it will over heat. This parameter is used to set coefficients of the frequency inverter
relay protection to the motor.
Motor OL protection coefficients =motor protection coefficients / motor rated coefficients
While one inverter for multi-motor, this function does not work. To protect motor, please install heat protection
relay at every motor input terminal.

interval
Malfunction auto-reset times:
0: Off No automatic reset function.
1-5: On 1-5 is times of automatic reset after fault.
Output terminal can be selected to act or not act in automatic reset process. Details refer to [F2.29-F2.31] .
Malfunction auto-reset interval: It defines waiting time before resetting after fault.
Note: 1. This function is only valid for fault of OL, OC, system abnormity, under voltage. Not valid for other
faults.
2. Can not reset before dealing with malfunction.
Attention: Please use this function carefully in occasions that can not start with load, or that needs alarm
immediately while inverter no output.
