The RST Restart function can be performed by two different
methods based on the “bit” settings (00~11).
For faults other than LV: If Bit 0 is turned on, the inverter resets
and restarts after a trip occurs.
For LV faults: If the Bit 1 is turned on, the inverter restarts after a LV
Fault.
The number of attempts to reset and restart is set at PRT-09 (Auto
Restart Count). If a fault occurs during operation, the inverter
automatically restarts after the set time programmed at PRT-10
(Retry Delay). At each restart, the inverter counts the number of
attempts and subtracts it from the number set at PRT-09 until the
retry number count reaches 0.
After an auto restart, if a fault does not occur within 60 sec, it will
increase the restart count number.
At auto restart, the acceleration options are identical to those of
speed search operation. Parameters CON-72–75 can be set
based on the load. Information about the speed search function
refer to 5.5.3 CON-70 Speed Search Operation on page 156.
