+ Protective operation detection relay signals (FLA, FLB, FLC terminal signals) are not sent during use of
the retry function. (Default setting)
+ To allow a signal to be sent to the protective action detection relay (FLA, B and C terminals) even during
the retry process, assign the function 36 or 37 to
H.
+ A virtual cooling time is provided for overload tripping (QN,QN).
In this case, the retry function operates after the virtual cooling time and retry time.
+ In the event of tripping caused by an overvoltage (QR - QR), the retry function will not be activated
until the voltage in the DC section comes down to a normal level.
+ In the event of tripping caused by overheating (QJ), the retry function will not be activated until the
temperature in the inverter comes down low enough for it to restart operation.
+ The retry function does not work even though H is activated in case of powering-up with H=
after trip.
+ During retrying, the blinking display will alternate between TVT[ and the monitor display specified by
status monitor display mode selection parameter
H.
+ The number of retries will be cleared if the inverter is not tripped for the specified period of time after a
successful retry.
"A successful retry" means that the inverter output frequency reaches the command frequency without
causing the inverter to re-trip.
