• Communications Writing
Set the Communications Writing parameter to "ON: enabled" or "OFF: disabled" with the related
information setting. The setting can be accepted in both setup area 0 and setup area 1. An
operation error will occur, however, if enabling or disabling communications writing is set for an
event input.
• RUN/RESET
Set the related information to select starting or stopping program operation. The setting can be
accepted in both setup area 0 and setup area 1.
• AT Execute/Cancel
Set AT (auto-tuning) to “execute” or “cancel” with the related information setting. This command
can be accepted in setup area 0 only. An “operation error” will be generated in the following
instances:
• When the RUN/RESET parameter is set to RESET (and the reset operation is set to stop
control).
• During standby status (when the reset operation is set to stop control).
• In manual mode or when executing from setup area 1.
• When ON/OFF control is being used
• When an attempt is made to execute another type of AT during AT execution
Example: When 40% AT is specified during 100% AT execution.
