Remedy
(1)Check the following settings.
･ Check the IO module configuration of the corresponding fieldbus
board in maintenance mode.
･ Check the switch settings on the corresponding fieldbus board.
･ Check the settings of the device to communicate with the
corresponding fieldbus board.
(1)Reset the alarm.
(2)If the alarm occurs again, check the connection and inserting state
of the following cables and connectors.
･ Communication connector and communication cable of the
corresponding fieldbus board.
･ Communication connector and communication cable of the device
that communicates with corresponding fieldbus board.
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the following board. Save the
CMOS.BIN before replace the board to be safe.
･ Corresponding fieldbus board
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace the CPU-201R board.
Move the manipulator in teach mode to the position where there is no torque on
the driving belt.
(1) Check the timing belt tension.
(1)Reset the alarm.
(2)If the alarm occurs again, turn the controller power OFF and then ON to
check the operation.
(3)If the alarm occurs again, initialize the appropriate data in maintenance
mode, and then load the data saved in the external memory device.
(1)Reset the alarm, and then try again.
(2)If the alarm occurs again, save the CMOS.BIN in maintenance mode, and
then contact your YASKAWA representative about occurrence status (operating
procedure).
(1)Reset the alarm, and then try again.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
