Caution
The Inverter might be damaged when using the fault restart function.
Understanding that the Inverter might be damaged, be sure to take the following pre-
cautions:
Always set up a no-fuse breaker (NFB).
Set up a sequence that will stop peripheral equipment when an Inverter fault occurs.
•
The fault restart function automatically restarts the Inverter even when an internal fault occurs during
Inverter operation.
•
Use this function only when continuing operation is more important than damaging the Inverter.
•
The fault restart function is effective with the following faults. With other faults, the protective opera-
tions will engage immediately without attempting to restart operation.
OC (Over-current)
GF (Ground fault)
PUF (Fuse blown)
OV (Main circuit over-voltage)
UV1 (Main circuit under-voltage)
PF (Main circuit voltage fault)
LF (Output open-phase)
RF (Braking resistor overheated)
RR (Braking transistor failure)
OL1 (Motor overload)
OL2 (Inverter overload)
OL3 (Overtorque)
OL4 (Overtorque)
•
The fault restart count is cleared when operation is normal for 10 minutes after a fault restart is per-
formed or the power is turned off and then on again.
•
When one of the multi-function outputs (H2-01, H2-02, or H2-03) is set to 1E (Restart Enabled), the
output will be ON while the fault restart function is in progress.
