LED Display Explanation Default
OUT: Output value display and output value adjustment in manual tuning
control (This function is not available in ON/OFF control or Auto-tuning
setting)
0
2. Regulation function mode: Set the control parameters
LED Display Explanation Default
AT: Auto-tuning setting. When AT key is set to ON (
), the execution
of the PID auto-tuning function is automatically started. (PID control)
OFF
P: Proportional Band (PID control) 2.1
I: Integral Time (PID control) 260
D: Derivative Time (PID control) 41
PdoF: Offset output when P or PD control function is ON.
(PID control and Ki=0)
0
ioF: Default value of integral volume when PID control function is ON and
integral time constant is not equal to 0(zero). AT can automatically set this
parameter. (PID control and Ki≠0)
0
