Parameter Description
Parameters
164
● Function of regeneration and avoidance: When the regenerative status is serious, the DC
bus voltage rises and an overvoltage alarm OV may occur. The function is to improve the
output frequency of inverter and decrease the DC bus voltage for avoiding alarm OV when
overvoltage happens(as the following shows).
