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.
