7-5-10 Output Voltage Gain
Use this function to decrease the inverter output voltage as a percentage of the voltage set in the
1st/2nd Motor Rated Voltage Selection (A082/A282).
You can avoid motor hunting by decreasing the output voltage gain.
Be sure to change the gain value moderately during operation (as a guide, 10% max.) Otherwise, an
overcurrent trip may occur due to sudden output voltage changes.
When the 1st/2nd Control Method (A044/A244) is set to 03 (Sensorless vector control), you can change
the set data during operation or stop, but changes will not be reflected on the control behavior. After
changing the setting, be sure to turn off and then on the input power supply again. Then, the inverter
recalculates the motor parameter values.
This motor parameter calculation is also performed when the reset input turns ON.
