Supplemental Information on AT Operation
• Perform AT with the control set point set and the power supply to the output side (e.g., heater)
turned ON.
• You can start AT from any current temperature.
Additional Information
• PID Constants
When control characteristics are already known, PID constants can be set directly to
adjust control. The PID constants are set in the following parameters in the Adjustment
Level: Proportional Band (P), Integral Time (I), Derivative Time (D), Proportional Band
(Cooling) (C-P), Integral Time (Cooling) (C-I), and Derivative Time (Cooling) (C-D).
• Integral/Derivative Time Unit
If the results of executing AT give a derivative time (D) of less than 10 seconds, we
recommend that you set the Integral/Derivative Time Unit parameter (Advanced Setting
Level) to 0.1 seconds and perform AT again.
