Name
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.
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.
If the disconnection due to the Bus-Off signal or timeout
occurs during the operation using DeviceNet commands,
the inverter will shut off its output and display the error
code.
(The inverter will trip according to the settings of "P045"
and "P048".)
If two or more devices having the same
MAC ID are detected in the same network, the inverter will
display the error code shown on the right.
If the Force Fault/Trip bit of Attribute 17 in the Instance 1
of the Control Supervisory object is set to "1", the inverter
will shut off its output and display the error code shown on
the right.
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 timeout occurs during the communication between the
inverter and DeviceNet option board,
the inverter will shut off its output and display the error
code shown on the right.
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.
