NOTE:
Reset is not allowed in 10 second after trip.
NOTE:
When error E08, E14 and E30 occur, reset operation by RS terminal or STOP/RESET key is
not accepted. In this case, reset by cycling power. If still same error occurs, perform initialization.
Name
When communication between two CPU fails, inverter
trips and displays the error code.
The inverter will trip if the power supply establishment is
not recognized because of a malfunction due to noise or
damage to the main circuit element.
An internal inverter error has occurred at the safety
protection circuit between the CPU and main driver unit.
Excessive electrical noise may be the cause. The inverter
has turned OFF the IGBT module output.
When a thermistor is connected to terminals [5] and [L]
and the inverter has sensed the temperature is too high,
the inverter trips and turns OFF the output.
When "01" has been specified for the Brake Control
Enable (b120), the inverter will trip if it cannot receive the
braking confirmation signal within the
Brake Wait Time for Confirmation (b124) after the output
of the brake release signal.
Safe stop signal is given when b145 =01.
If overload occurs during the motor operation at a very low
speed, the inverter will detect the
overload and shut off the inverter output.
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
(P072-P073), the inverter will shut off its output and
display the error code.
Safe stop signal is given when b145 =02.
Safe stop signal is given when b145 =02, 03 or 05.
