Description
By measuring process response, the respective optimal values for Kp, Ti and Td as PID
parameters are measured. When auto-tuning is executed, the estimated results are
reflected in the parameter area after auto-tuning is complete.

When not executing auto-tuning
H0: Derivative-first, reverse operation
H1: Derivative-first, forward operation
H2: Proportional-plus-derivative-first, reverse operation
H3: Proportional-plus-derivative-first, forward operation
When executing auto-tuning
H8000: Derivative-first, reverse operation
H8001: Derivative-first, forward operation
H8002: Proportional-plus-derivative-first, reverse operation
H8003: Proportional-plus-derivative-first, forward operation
Set the target value for the process control within the following
range.
Use an A/D conversion unit, etc., to input the current value of
process control.
PID operation result is stored. Output the value using a D/A
converter, etc.
Specify the output value (MV) range. Values for the specified
range are output.
Specify the coefficient used for PID operation. The setting
value × 0.1 is the actual proportional gain.
