High−level Instructions
Output upper limit value
6
K1 to K10000 (> lower limit value)
Specify the output value (MV) range. Values specified for the range are output.
The limits should be as follows:
0 output lower limit value < output upper limit value
Proportional gain (Kp)
7
Specify the coefficient used for PID processing.
The set value × 0.1 will be the actual proportional gain.
The setting range is K1 to K9999 (0.1 to 999.9, specify in increments of 0.1)
If auto-tuning is selected for the specified control mode, the set value will be automatically
adjusted and rewritten.

8
Specify the coefficient used for PID processing.
The set value × 0.1 will be the actual integral time.
The setting range is K1 to K30000 (0.1 to 3000 seconds, specify in increments of 0.1 seconds)
When the set value is 0, the integration is not executed.
If auto-tuning is selected for the specified control mode, the set value will be automatically
adjusted and rewritten.
Derivative time (Td)
9
Specify the coefficient used for PID processing.
The set value × 0.1 will be the actual derivative time.
The setting range is K1 to K10000 (0.1 to 1000 seconds, specify in increments of 0.1 seconds)
If auto-tuning is selected for the specified control mode, the set value will be automatically
adjusted and rewritten.
Control cycle (Ts)
10
Set the cycle for executing PID processing. The set value × 0.01 will be the actual control period.
The setting range is K1 to K6000 (0.01 to 60.0 seconds, specify in increments of 0.01 seconds).
Auto-tuning progress
11
If auto−tuning is specified in the control mode, the degree to which auto−tuning has progressed
is indicated. The values for K1 to K5 are stored based on the progress from the default value of 0,
and the values return to the default values when auto−tuning has been completed.
PID processing work area
12
The system uses this work area to perform PID processing.
For the FP0 use the 20 words, [S+11] to [S+30], as the work area.
