Avr Function; Automatic Energy-Saving Operation Function - Omron 3G3JX User Manual

4-2 Function Mode

AVR Function

•This function outputs voltage to the motor correctly even if the incoming voltage to the Inverter
fluctuates. With this function, output voltage to the motor is based on that set in the AVR voltage
selection.
Parameter No.

•With A081 (AVR selection), set whether to enable or disable this function.
•Note that the Inverter cannot output voltage beyond that of the incoming voltage.
•To avoid a possible overcurrent trip during deceleration, set the AVR selection to "Always ON"
(A081: 00).
Parameter No.
A081

Automatic Energy-saving Operation Function

This function automatically adjusts the Inverter output power to a minimum during constant speed
operation. This is suitable for the load of reduced torque characteristics, such as a fan and pump.
Parameter No.
A085
A086
•To operate with this function, set the RUN mode selection (A085) to 01. You can adjust the
response and accuracy in the energy-saving response/accuracy adjustment (A086).
•Controls the output power at a comparatively slow rate. Should rapid load fluctuation like impact
load occur, the motor may stall, resulting in an overcurrent trip.
Parameter No.

Enabled during acceleration, constant speed operation, and
deceleration.
Disabled during acceleration, constant speed operation, and
deceleration.
Disabled only during deceleration in order to reduce the energy
regenerated to the Inverter by increasing the motor loss. This will
avoid a possible trip due to regeneration during deceleration.
