suppression
STOP
Note: Overvoltage suppression is valid for any control method.
When the bus voltage during the running of the drive reaches or falls below F10.17 [bus undervoltage suppression point], the drive will automatically adjust
the operating frequency to suppress the bus voltage drop, thus ensuring that the drive does not trigger E.LU2 due to the low bus voltage. [Undervoltage
fault].

suppression gain
RUN
Adjust F10.18 [Bus Undervoltage Suppression Gain] to adjust the effect of the undervoltage suppression function. When this parameter is set to 0, the
undervoltage suppression function is turned off.

protection point
STOP
This parameter specifies the lower limit voltage allowed by the bus voltage when the drive is working normally. For some occasions where the grid is low,
the undervoltage protection level can be appropriately reduced to ensure the normal operation of the drive.
Note: When the grid voltage is too low, the output torque of the motor will decrease. For constant power loads and constant torque loads, too low grid
voltage will increase the input and output current of the drive, thus reducing the reliability of the drive operation.
