WAIT TIME (Parameter P50)
Used to set the wait time for the start mode, the ride-through restart and retry functions.
Data setting range
RETRY FUNCTION SELECT, NO. OF RETRIES
CAUTION
When the retry function is used, the unit may automatically start (restart) suddenly so
do not approach the unit.
(Secure personal safety before using this function.)
Failure to do so could lead to injury.
♦ If an inverter fault trip occurs, the retry function will automatically reset the fault and will
restart (start) operation after the wait time has elapsed.
Use this function to continue operation.
· Select the "retry function validity" and the details of the fault for carrying out retry with
parameter P51.
· Set the "number of times to retry" with parameter P52.

· The fault warning signal will not be output during retry.
If a fault occurs even when the set number of retries has been carried out, a fault
warning signal will be issued.

counted number of retries will be cleared.
· The counted number of retries will be cleared when the power is turned OFF.

cleared.
