• Function
When a motor is in unstable with light load, this parameter can change the motor gain to make motor
condition stable. First set H =and check the motor condition. Please set to in case motor
needs more stable condition. This parameter is effective only in V/F control mode (RV =,,)
• Function
In the case that Inverter output voltage drops and output current exceeds motor rating current at the frequency
higher than base frequency, Change this parameter setting and check whether the output current is reduced.
