(common)
When a power failure or undervoltage occurs, the inverter can be decelerated to a stop or can be decelerated and re-
accelerated to the set frequency.

When undervoltage or a power failure
occurs, the inverter can be

UV avoidance voltage gain 100% 0 to 200%
Adjusts the response level during undervoltage
avoidance operation. A larger setting will improve
responsiveness to the bus voltage change. Since the
regeneration amount is large when the inertia is large,
decrease the setting value.
