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 selection of 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 0.1 to 600s.

Reading the Pr. 69 value provides the cumulative number of
successful restart times made by retry. (This can be cleared by
setting "0".)
Setting of the used motor selects the thermal characteristic
appropriate for the motor.
Setting is required when using a constant-torque motor or IPM
motor. Thermal characteristic of the electronic thermal relay
function suitable for the motor is set.
 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 setting as follows.

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