The inverter shuts off the output when the PID output becomes less than the

specified value (
quency command becomes less than the specified value in case of PID is set
disabled. And if the PID output or frequency command exceeds the specified
A156
value ( ) for a specified period (
operation. This is the PID sleep function.

• PID Sleep function is always enabled, even the PID function is disabled.
The automatic voltage regulation (AVR) feature keeps the inverter output
waveform at a relatively constant amplitude during power input fluctuations.
This can be useful if the installation is subject to input voltage fluctuations.
However, the inverter cannot boost its motor output to a voltage higher than
the power input voltage. If you enable this feature, be sure to select the proper
voltage class setting for your motor.

AVR filter time constant
AVR deceleration gain
Note The motor behave as generator during deceleration and the energy is regen-
erated to the drive. As a result, the DC voltage in the inverter increases and
cause over-voltage trip when exceeding the OV level. When the voltage is set
high, deceleration time can be set shorter thanks to the energy consumption
due to the increase of losses in inverter. In order to set deceleration time
shorter without over-voltage trip, please try to set AVR off during deceleration
or to tune the AVR filter time constant and AVR deceleration gain.

AVR functions, three option
codes:
00... AVR enabled
01... AVR disabled
02... AVR enabled except during
deceleration
200V class inverter settings:
200/215/220/230/240
400V class inverter settings:
