Notes:
(1) Fault restart function contains momentary power loss restart and auto reset restart.
(2) Refer to chapter 10 for the for troubleshooting and fault diagnostics.
(3) Refer to speed search function (07-19~07-24) for speed search modes selection when power is restored.
Fault reset time (07-01)
Time the inverter waits to reset fault.
Momentary power loss restart time is the same as Fault reset time.
07-01 <07-18: Automatic restart time interval is set by minimum baseblock time (07-18).
07-01> 07-18: Automatic restart time interval is set by fault reset time (07-01).
Note:
Total automatic restart interval time is 07-18 plus 07-01 plus speed search delay time (07-22).
Refer to Figure 4.3.55 for automatic restart interval time.

Figure 4.3.55 Automatic restart interval
Number of restart attempts (07-02)
When the total number of restart attempts has exceed the number of automatic restart attempts set in parameter
07-02, the inverter will turn off the output and the fault contact is activated. Manually resetting the inverter is
required at this time.
When the automatic restart function is enabled the internal automatic restart attempt counter is reset based on
the following actions:
1. No fault occurs in 10 minutes or longer after the automatic restart
2. Reset command to clear fault via input terminal or using the keypad (press reset/
key)
3. Power to the inverter is turned off and back on again
Note
:
Multi-function digital output R1A-R1C, R2A-R2C can be programmed to activate during an automatic reset
attempt, refer to parameter 03-11, 03-12, function 06.
