Cause(s)
When the connection between inverter and
operator keypad failed, inverter trips and displays
the error code.
When "trip" is selected (C076=00) as a behavior in
case of communication error, inverter trips when
timeout happens.
The program stored in inverter memory has been
destroyed, or the PRG terminal was turned on
without a program downloaded to the inverter.
Subroutines, if-statement, or for-next loop are
nested in more than eight layers
Inverter found the command which cannot be
executed.
When user –defined trip happens, inverter trips
and displays the error code.
The inverter detects errors in the option board
mounted in the optional slot. For details, refer to
the instruction manual for the mounted option
board.
If the encoder wiring is disconnected, an encoder
connection error is detected, the encoder fails, or an
encoder that does not support line driver output is
used, the inverter will shut off its output and display
the error code shown on the right.
If the motor speed rises to "maximum frequency
(A004) x over-speed error detection level (P026)" or
more, the inverter will shut off its output and
display the error code shown on the right.
If current position exceeds the position range
(P072-P073), the inverter will shut off its output
and display the error code.
