The fault restart function will restart the inverter even when an internal fault occurs
during inverter operation. Use this function only when continuing operation is more
important than possibly damaging the inverter.
The fault restart function is effective with the following faults. With other faults, the
protective operations will engage immediately without attempting to restart
operation.
Over-current Ground fault Main circuit over-voltage
The fault restart count will automatically increase upon the restart activated and will
be cleared in the following cases:
a. When the operation is normal for 10 minutes after a fault restart is performed.
b. When the fault-reset input is received after the protection operation has been
activated and the fault confirmed. (e.g., by pressing RESET or enable Fault reset
terminal 􀁥)
c. When the power is turned off and on again.
When one of the multi-function output terminals (RA-RB-RC or R1A-R1B-R1C,
DO1, DO2 or R2A-R2C) is set to restart enabled, the output will be ON while the
fault restart function is in progress. See page 90 for the setting of (Sn-30~Sn-32).
