■ Description of Operation Instructions and Precautions
•Write Mode
Set either the Port B backup mode or RAM write mode using the related
information. (The default is RAM write mode.)
When the mode is switched from RAM write mode to backup mode, the
settings for the parameters that can be changed during operation are not
written to EEPROM. Execute the Save RAM Data command if required.
Note Settings that are changed from port A are always written to EEPROM. Be
sure to consider the limit to the number of writes when using port A.
• Software Reset
Executes a software reset.
A software reset performs the same operation as when the power is
cycled.
Execute a software reset only when control operations are stopped for all
channels.
• RUN/STOP
Starts or stops operation for the channels specified in the related informa-
tion.
• Auto/manual Switch
Switches between manual mode and automatic mode for the channels
specified in the related information. When switching from automatic to
manual mode, the MV will be written to EEPROM.
An operation error is generated in the following instances:
• ON/OFF control
A Normal End is returned when Automatic Mode is executed when al-
ready in automatic mode or Manual Mode is executed when already in
manual mode.
• Switching to Manual Mode during Execution of AT
If AT is being executed, AT is canceled and the mode switched to man-
ual mode.
• 40% AT Execute/Cancel and 100% AT Execute/Cancel
Selects executing or canceling autotuning for the channels specified in
the related information. An “operation error” is generated in the following
instances:
• When the “run/stop” parameter is set to “stop.”
• When the “auto/manual” parameter is set to “manual.”
• During ON/OFF control.
• When 100% AT Execute is specified during 40% AT Execute execu-
tion.
• When 40% AT Execute is specified during 100% AT Execute execu-
tion.
• Bank 0 Change to Bank 3 Change
Switches between banks 0 to 3. Refer to 4-7-1 Bank Function for details
on banks.
An operation error will occur if autotuning is already being performed for a
specified channel.
