Mitsubishi Electronics FR-F700 Pr Energy saving control selection, Retry function at alarm

Pr. 60 Energy saving control selection

Pr.60 Energy saving control

Without a fine parameter setting, the inverter automatically performs energy saving operation.

This inverter is optimum for fan and pump applications.

Pr. 60 Setting	Description
0 (initial value)	Normal operation mode
	Energy saving operation mode
	In the energy saving operation mode, the inverter
4	automatically controls the output voltage to
	minimize the inverter output voltage during a
	constant operation.
	Optimum excitation control mode
	The optimum excitation control mode is a control
9	system which controls excitation current to
	improve the motor efficiency to maximum and
	determines output voltage as an energy saving
	system.

Pr.65 Retry selection	Pr.67 Number of retries at alarm occurrence
Pr.68 Retry waiting time	Pr.69 Retry count display erase

If an alarm occurs, the inverter resets itself automatically to restart. You can also select the alarm description for a retry. When selection of automatic restart after instantaneous power failure is selected (Pr. 57 Restart coasting time, restart operation is performed at retry operation as at an instantaneous power failure.)

￿Use Pr. 65 to select the alarm to be activated for retries. "￿" indicates the alarms selected for retry.

￿Set the number of retries at alarm occurrence in Pr. 67.

Pr. 67 Setting	Description
0 (initial value)	No retry function
	Set the number of retries at alarm occurrence.
1 to 10	An alarm output is not provided during retry
	operation.
	Set the number of retries at alarm occurrence.
	(The setting value of minus 100 is the number
101 to 110	of retries.)
	An alarm output is provided during retry
	operation.

￿Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a retry is made in the range 0 to 10s.

￿Reading the Pr. 69 value provides the cumulative number of successful restart times made by retry.

Pr. 66		Refer to the section about Pr. 22		and other
		relevant parameters.
Pr. 67 to 69			Refer to the section about Pr. 65 and

Pr.		Use the constant torque motor
	71 (applied motor)

Pr.71 Applied motor

Setting of the used motor selects the thermal characteristic appropriate for the motor.

Setting is necessary when using a constant-torque motor. Thermal characteristic of the electronic thermal relay function suitable for the motor is set.
