
For LV fault trips
For fault trips other than LV : If the Bit 0 is turned on, the inverter
restarts after a trip occurs and triggers a reset.
For LV fault trips : If the Bit 1 is turned on, the inverter restarts after a
trip occurs and triggers a reset.
PRT-09
Retry Number,
PRT-10
Retry Delay
The number of available auto restarts can be set at PRT-09. If a fault
trip occurs during an operation, the inverter restarts after the time set at
PRT-10 (Retry Delay). At each restart, the inverter counts the number of
tries and subtracts it from the number set at PRT-09 until the retry
number count reaches 0. After an auto restart, if a fault trip does not
occur within 60 sec, it will increase the restart count number. The
maximum count number is limited by the number set at PRT-09.
If the inverter stops due to over current or hardware diagnosis, an auto
restart is not activated. At auto restart, the acceleration options are
identical to those of speed search operation. Codes CON-72
–75 can be
set based on the load. Information about the speed search function can
be found at 5.27 Speed Search Operation on page
234 .
[Example of auto restart with a setting of 2]
•
If the auto restart number is set, be careful when the inverter resets from a fault trip. The
motor may automatically start to rotate.
•
In HAND mode, auto restart resets the trip condition but it does not restart the inverter
operation.
