7.2.1 Standard control (such as auto tuning, self-tuning, and error code read)
(f) Program example
• Program that changes the setting/operation mode
• Program that stops the auto tuning when an alert is detected
• Program that reads the PID constants from E
2
PROM
• Program that reads an error code
• Program that changes the set values (SV) and the alert set value 1
Change to the setting mode or
the operation mode.
