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.

Motor selection (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.
