Disabling An Option Unit - Yamaha RCX340 User Manual

10. Disabling an option unit

If the controller is equipped with a field network option unit, it normally communicates with the host control
device and controls the robot in accordance with the communicated content, so a ladder program is required
for the host control device.
When performing teaching or trial operation of the robot by itself in a state in which the host control device's
10
ladder program has not been provided, the robot can be operated without communicating with the host
control device by setting the option board to "disabled".
c
CAUTION
When shipped from the factory, all functions of the option unit are set to "enabled." In the "enabled" state, the robot
first becomes operable when an emergency stop or stop signal is input from the host control device.
For details on I/O functionality, refer to the separate "Remote I/O Manual".

CAUTION
The "Option board enable" parameter is set individually for option slots 1 through 4. When changing the settings of
an option board, be sure to verify the location in which the target option board is installed, and change the setting
only for the target slot number.
The illustration below shows the correspondence between the location of each option slot and the actual
installation location.
