4.9 Reset and Restart
Reset and restart operations can be setup for inverter operation following a fault trip, based
on the terminal block operation command (if it is configured). When a fault trip occurs, the
inverter cuts off the output and the motor will free-run. Another fault trip may be triggered if
the inverter begins its operation while motor load is in a free-run state. In PRT-08, bit 1 sets
the option for all the fault trips, other than low voltage trips, and bit 2 sets the option for low
voltage trips. PRT-10 sets the delay time for restart (the time for the inverter to wait before it
restarts).
The number of auto-restarts (PRT-09) refers to the number of times the inverter will try
restarting its operation. If fault trips occur again after restart, the retry number counts down
each time the inverter restarts until the number becomes ‘0.’ Once the inverter restarts
successfully after the initial fault trip, the inverter does not restart until the next fault trip
occurs. The number of auto-restarts set at PRT-09 that decreased after a restart reverts to
the original setting value if successful operation continues for certain period of time.
