Fault reset time (07-01)
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 4.3.55 for automatic restart interval.
Figure 4.3.55 Automatic restart interval
Number of restart attempts (07-02)
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 to 0 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 keypad (press reset/ key)
(3) Power to the inverter is turned off and back on again
Note:
Multi-function digital output R1A-R1C, R2A-R2B, or optocoupler output can be programmed to
activate during an automatic reset attempt, refer to parameter 03-11, 03-12.
Automatic restart operation:
(1) Fault is detected. The inverter turn off the output, displays the fault on the keypad and waits for
the minimum baseblock time parameter 07-18 to expire before accepting another run
/automatic restart command.
(2) 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.
(3) When the total number of restart attempts exceed the number of automatic restartattempts set
in parameter 07-02, the inverter will turn off the output and the fault contact is activated.
