Automatic Fault Restart

Automatic Fault Restart

The inverter can be set to restart automatically after a fault occurs. The maximum number of restarts can be
selected.

Auto-resetable Fault codes are: UV1, GF, OC, OV, OL2, OL3, OL4, UL3, UL4, PF, LF

Related Constants.

Number of restarts

The number of reatarts can be set in parameter L5-01. The fault restart intervall time is 2.0 sec.

Fault Relay Operation

Parameter L5-02 can be used to enable or disable the fault relay (terminal MA-MB-MC) during fault retry
condition.

•

L2-02 = 1 enabled the fault relay.

•

L2-02 = 0 disables the fault relay.
