Mitsubishi FR-E 500 Instruction Manual page 111

Note: 1. Automatic restart after instantaneous power failure uses a reduced-voltage
starting system in which the output voltage is raised gradually with the preset
frequency unchanged, independently of the coasting speed of the motor.
As in the FR-A024/A044, a motor coasting speed detection system (speed
search system) is not used but the output frequency before an instantaneous
power failure is output. Therefore, if the instantaneous power failure time is
longer than 0.2 s, the frequency before the instantaneous power failure
cannot be stored and the inverter will start at 0Hz.
2. The SU and FU signals are not output during restart but are output after the
restart cushion time has elapsed.
When automatic restart after instantaneous power failure has been
selected, the motor and machine will start suddenly (after the reset time
has elapsed) after occurrence of an instantaneous power failure.
Stay away from the motor and machine.
When you have selected automatic restart after instantaneous power
failure, apply the supplied CAUTION seals in easily visible places.
When the start signal is turned off or the
cushion time for automatic restart after instantaneous power failure,
deceleration starts after the automatic restart cushion time set in Pr. 58
"cushion time for automatic restart after instantaneous power failure"
has elapsed.
