Reset method of protective function
When a fault occurs in the inverter, the inverter trips and the PU display automatically changes to any of the following fault or
alarm indications.
If the fault does not correspond to any of the following faults or if you have any other problem, please contact your sales
representative.
Retention of fault output signal
...When the magnetic contactor (MC) provided on the input side of the inverter is opened
when a fault occurs, the inverter's control power will be lost and the fault output will not be
held.
Fault or alarm indication ..........When a fault or alarm occurs, the operation panel display automatically switches to the fault
or alarm indication.
Resetting method ....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter
cannot restart. (Refer to page 248)
When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.
Not doing so may lead to the inverter fault and damage.
Inverter fault or alarm indications are roughly divided as below.
(1) Error message
A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04 /FR-PU07)
is displayed. The inverter does not trip.
(2) Warnings
The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a
fault.
(3) Alarm
The inverter does not trip. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter trips and a fault signal is output.
5.1 Reset method of protective function
(1) Resetting the inverter
The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the
electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Recover about 1s after reset is cancelled.
Operation 1: ...... Using the operation panel, press to reset the inverter.
(This may only be performed when a fault occurs (Refer to page 253 for
fault.))
Operation 2: ....... Switch power off once, then switch it on again.
Operation 3: . ..... Turn on the reset signal (RES) for more than 0.1s. (If the RES signal
is kept on, "Err." appears (flickers) to indicate that the inverter is in a
reset status.)
