When setting parameters, refer to the instruction manual (applied) and understand instructions.
If an alarm occurs, the inverter resets itself automatically to restart.
You can also select the alarm description for a retry.
When automatic restart after instantaneous power failure is
selected (Pr.57 Restart coasting time
≠9999), 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.
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.
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.
*1 Motor constants of Mitsubishi high efficiency motor SF-HR
*2 Motor constants of Mitsubishi constant-torque motor SF-HRCA.
*3 Star connection
*4 Delta connection
For the 5.5K and 7.5K, the Pr. 0 Torque boost and Pr. 12 DC injection
brake operation voltage settings are automatically changed according
to the Pr. 71 and Pr.450 settings as follows.
