Operation After Recovery from Power Interruption
Setting range 0, 1, 2 Factory setting 0
This constant is used to select the processing to be performed after recovery from an
instantaneous power interruption.
Value Description
0 Discontinues operation.
1 Continues operation only if power interruption is within 0.5 second.
2 Continues operation unconditionally (with no error output).
Note If “1” or “2” is selected to continue operation, the Inverter automatically searches
the motor speed (even when the motor is in a free-running state) and continues
smooth operation. This function is called the speed search function.
