07-00=0
: Inverter trips on “UV” fault if power loss time is greater than 8ms.
07-00=1
: Inverter restarts after restarting the power at the momentary power loss.
Note:
When 07-00=1, inverter restore automatically the motor rotation after restarting the power even if
momentary power loss occurs.
07-01
Fault reset time
Range
0~7200 Sec
Restart time of momentary power loss 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:
Automatic restart time interval is time of 07-18 plus 07-01 and delay time of peed search (07-22).
Refer to Figure 4.4.55 for automatic restart interval.

Number of restart attempts
Range
0~10
If numbers of fault reset reaches the setting value of 07-02, then inverter stops running. So manual to restart the
inverter after eliminating fault causes.
When the automatic restart function is enabled the internal automatic restart attempt counter is reset based on
the following actions:
a) No fault occurs in 10 minutes or longer after the automatic restart
b) Reset command to clear fault via input terminal or using the keypad (ex: press reset/
key)
c) Power to the inverter is turned off and back on again
Note:
Multi-function digital output R1A-R1C, R2A-R2C, or optocoupler output can be programmed to activate during an
automatic reset attempt, refer to parameter 03-11, 03-12 and 03-28.
