Please install the USB driver of the
communication unit.
The USB driver's installation starts when
the communication unit is connected
with PC. Details of the installation
procedure are shown in "Installation
procedure of the JXC-W2 setting
software".
The COM port allocated to the controller
is different for different PC's. Check and
confirm the COM port number with the
controller connected to the PC.
The COM port number can be checked
using the Device Manager of the PC.
For details of the COM port checking
and setting methods refer to the
"JXC-W2 Controller Configuration
Software Installation Manual".
Please confirm motor controller (JXC) =
communications cable = communication
unit = USB cable = PC is connected. For
example, communication cannot be
established if the connector has been
damaged.
Please confirm the power supply of
motor controller (JXC) has been turned
ON. Communication cannot be
established if the power supply is OFF.
If equipment other than the motor
controller (JXC) (PLC and measurement
equipment) is connected with PC,
remove these before checking. (There is
a possibility that the communication with
other equipment interferes in PC.)
If there is no sound of lock release, the
lock brake may be broken.
