When a protective function is activated,
the output of the inverter is switched off.
The motor runs until stop. The output
remains switched off until the error cause
is eliminated and the inverter is reset.
The inverter can be reset following four
different methods:
앬
Switch the power supply OFF and ON
again.
앬
Switch the reset signal ON for at least
0.1 s and switch it OFF again.
앬
Press the RESET key on the control
panel.
앬
Menu-guided reset via the optional
parameter unit FR-PU04
If the reset signal is ON continuously, the
control panel FR-PA02-02 returns an error
message while the control unit FR-PU04
indicates that the reset procedure is in
progress.
When a protective function is activated,
the control panel FR-PA02-02 returns an
error code as listed in the table above.
The parameter unit FR-PU04 indicates a
more detailed error message.
If an error occures and the input protection
contactor is toggled the error message can-
not be retained, since there is no power
supply for the control circuit.
