PID Feedback Value Monitor
•You can monitor the PID feedback value.
•The monitor value is displayed as the product of the feedback value and PID scale A075.
"Monitor display" = "Feedback value (%)" × "A075 setting"
PID Integral Reset
•Clears the integral value of PID operation.
•Allocate 24 (PIDC) to any of multi-function inputs C001 to C008.
•Clears the integral value every time the PIDC terminal is turned on.
Do not turn on the PIDC terminal during PID operation to avoid a possible overcurrent trip.
Turn on the PIDC terminal after turning off PID operation.

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 the voltage set in the motor
voltage selection.
Parameter No.

A082
Related functions
•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).

Enabled during acceleration, constant speed , and deceleration.
Disabled during acceleration, constant speed, 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.
