Description
Sets the retry counts in case of instanta-
neous power failure.
If this is set to 0, the motor will trip upon
recovery from instantaneous power failure.
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 if the instantaneous power failure
time is within the set value.
Starts after waiting for the set time upon
power voltage recovery.
Disabled
Enabled
Disabled during stop and deceleration stop
