Unsuitable
specification
Check that the controller parameter
settings for the product model and power
supply specification are appropriate for the
actuator connected.
Check that the controller parameters
matches with the actuator product
number.
Check that the power supply specification
is correct.

Signal timing
Check the timing of the signal from the
PLC to the controller.
Leave an interval of 15ms or more
(recommendation is 30 ms) between
signals and maintain the state of the signal
for 15ms or more (recommendation is 30
ms), because PLC processing delays and
controller scanning delays can occur.
->10.7 PLC output signal response time
SVON time
Check that the Operation was sent after
SVON is ON and SVRE is ON.
When the power is supplied, it may take
up to 20 seconds from servo ON to SVRE
ON depending on the actuator position or
conditions. Send an operation only when
the SVRE is ON.
Communication
fault
(JXC-W1)
The USB
driver is not
installed
Check that the USB driver for the USB
cable is installed.
Install the USB driver for the USB cable.
Details of the installation procedure are
given in the controller setting software
Installation Manual.
Connection
failure
Please confirm the connection status.
Confirm the correct connection of
controller (JXC), USB cable and PC. For
example, communication cannot be
established if the connector has been
damaged.
Check that the power supply to the
controller (JXC) has been turned on.
Communication cannot be established if
the power supply is off.
If any external equipment (PLC and
measurement hardware), other than the
controller (JXC), are connected to the PC,
disconnect them. (There is a possibility
that the other equipment in the PC may
interfere with the communication.)
