Mitsubishi Electric FR-F740 EC Instruction Manual page 315

Parameter
Original operation continuation at instantaneous power failure function (Pr. 261 = 2)
When power is restored during deceleration after an instantaneous power failure, acceleration
is made again up to the set frequency.
Fig. 6-97:
When this function is used in combination with the automatic restart after instantaneous power
failure operation, deceleration can be made at a power failure and acceleration can be made
again after power restoration. When power is restored after a stop by deceleration at an instan-
taneous power failure, automatic restart operation is performed if automatic restart after instan-
taneous power failure has been selected (Pr. 57 ≠ 9999).
