• P4.01 can be used to restart the inverter automatically even when an
internal fault occurs during inverter operation.
• Use P4.01 only when continuing operation is more important than
possibly damaging the inverter.
• The inverter may be damaged when using the fault retry function
too frequently.
• Since the inverter might be damaged, be sure to take the following
precautions:
- Always set up a molded-case circuit breaker
- Set up a sequence that will stop peripheral equipment when an
inverter fault occurs
• The fault retry function is effective with the following faults.
With others, the protective operation will engage immediately without
attempting to restart operation:
- overcurrent
- motor overload
- inverter overload
- main circuit overvoltage
- main circuit undervoltage
•The counter which counts the number of the past fault is cleared when:
-normal operation is maintained for 10 minutes.
-the fault reset input from digital operator or input terminal is
received after the protection operation.
-the input power supply is off.
