A virtual cooling time is provided for overload tripping (e-21, e-22). In this case, the retry
function will operate after the virtual cooling time and retry time.
In the event of tripping caused by an overvoltage (e-11), 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 (e-24), the retry function will not be
activated until the temperature in the inverter comes down low enough for it to restart
operation.
Keep in mind that when f429 is set to 1 (trip retained), the retry function will not be
performed, regardless of the setting of f400.
During retrying, the blinking display will alternate between a-08 and the monitor display
specified by status monitor display mode selection parameter f610.
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.
Retry available fault including overcurrent (e-01, e-04), overvoltage (e-11), overheat (e-
24), over load(e-21, e-22), and momentary power failure.
The retry function will be canceled at once if tripping is caused by an unusual event other
than the retry available fault. This function will also be canceled if retrying is not
successful within the specified number of times. “Function be canceled” means inverter
will be tripped and stop supply to motor.
The interval time is proportional relation with retry times. The first retry is 1sec, the
second retry is 2 sec and the 10
th
retry is 10sec.
