Restart Overvoltage
In case of overvoltage, you can restart without causing tripping.
Precautions for Correct Use
If overvoltage continues to be observed, there are some possible causes: short deceleration
time, heavy load, motor operated by external force, etc.

Description
Sets the retry counts in case of overvoltage.
If this is set to 0, the motor will trip upon
overvoltage.
Restarts at 0 Hz
Restarts with the frequency matching
Restarts upon frequency pull-in
Detection speed (frequency) <v2.00 or
higher>
Trips after decelerating and stopping with
the frequency matching
Restarts after waiting for the set time upon
overvoltage.
