● RUN/STOP
Set control to "run" or "stop" 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 RUN/STOP is set for an event
input.
● Bank Change
Select a bank from 0 to 7 with the related information setting. The
setting can be accepted in both setup area 0 and setup area 1. An
operation error will occur in the following situations.
• When AT is being executed
• When a bank change is set for the event input (Bank Numbers Used
parameter setting > 0)
When the program pattern is set to any setting other than OFF, the
bank number must be between 00 and the bank set for the Valid
Program Bank, and a parameter error will occur if the related infor-
mation setting exceeds the bank set for the Valid Program Bank
parameter setting.
● 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/STOP parameter is set to "stop"
• When the command is executed in "setup area 1"
• When ON/OFF control is being used
• When 40% AT is specified during 100% AT execution.
• When 100% AT is specified during 40% AT execution.
In addition, a parameter error will occur if 40% AT is specified during
heating and cooling control or during position-proportional floating
control.
Note: If the same type of AT execution is specified during AT execution
(e.g., if 100% AT execution is specified dur ing 100% AT
execution), the AT will not be restarted and the operation will end
in normal completion with no processing.
● Write Mode
Set either "backup mode" or "RAM write mode" with the related infor-
mation setting. The setting can be accepted in both setup area 0 and
setup area 1.
The number of EEPROM (non-volatile memory) write operations is
limited. Therefore, use RAM write mode when frequently overwriting
data.
