07 - Start/Stop Parameters
Code Parameter Name / Range
07-00 Momentary Power Loss/Fault Restart Selection
0: Disable
1: Enable
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.
Code Parameter Name / Range
07-01 Fault reset time
0~7200 s
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.

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.
Automatic restart operation:
a) Fault is detected. The inverter turn off the output, displays the fault on the keypad and waits for the mini-
mum baseblock time parameter 07-18 to expire before accepting another run / automatic restart command.
b) After the minimum baseblock time (07-18) and delay time of speed search have expired, the active fault
is reset and a speed search operation is performed. The time between each fault restart attempt is set by
parameter 07-01.
c) When the total number of restart attempts 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.
Please refer to Figure 4.4.56 for the automatic restart operation.
