Trip the inverter immediately if a momentary
power failure occurs.
Shut down the inverter output immediately to
allow the motor to coast to a stop without trip if
a momentary power failure occurs. Trip the
inverter when the power is restored.
Trip after
momentary power
failure (No
restart)
Decelerate the motor to a stop immediately if a
momentary power failure occurs. Trip the
inverter after the frequency drops down to zero.
