Mitsubishi Electronics FR-S500 Setting, Refer to the following table and set the parameters

Restart operation parameters

<Setting>

Refer to the following table and set the parameters:

Parameter		Setting	Description
	0	0.1K to 1.5K	Coasting time of 0.5s	Generally, this setting will pose
		2.2K, 3.7K	Coasting time of 1.0s	no problems.
57			Waiting time for inverter-triggered	restart after power is restored
		0.1 to 5s	from an instantaneous power failure. (Set this time between 0.1
			and 5s according to the moment (J) of inertia and torque of the
			load.)
58		- - -	No restart (factory setting)
		0 to 60s	Normally the motor may be run with the factory settings. These
			values are adjustable to the load (moment of inertia, torque).
			With speed search
		0	The motor coasting speed is detected after instantaneous power
			failure is detected.
			Without speed search (factory setting)
H6 (162)		1	Automatic restart operation after instantaneous power failure is a
			reduced voltage starting system in which the output voltage is
			risen gradually at the preset frequency independently of the
			coasting speed of the motor.
			With speed search at starting
		10	The motor coasting speed is detected after instantaneous power
			failure and at starting.
