VS070QS-1618MDM1 Integrated Machine Temperature autotuning PID
202403 (V1.0) 38
Appendix C Temperature autotuning PID
This command function block realizes the autotuning PID temperature control
function, and you can select one of the following five control modes as needed,
including: slow autotuning PID control mode, default manual PID control mode,
manual PID control mode, ON/OFF control mode, and fast autotuning PID control
mode.

S1: Set target temperature
S2: Present measured temperature
S3: Set the first address number of the soft element of the control parameter. Range
of proportional gain (Kp): 0–32767 (must be greater than 0), floating-point type
S3 + 2: Integral time (Ti). Range: 0–32767 (s). No integral processing is performed
when it is 0, floating point type.
S3 + 4: Differential time (Td). Range: 0–32767 (s). No differential processing is
performed when it is 0, floating point type.
S3 + 6: Sampling time (Ts). Range: 1–32767 (ms). Time values shorter than the
operation cycle cannot be executed.
S3 + 7: Sampling period. Range: 1–32767 (ms). When S+16 is 1,namely PWM
high-speed output is enabled, the relay switching period range changes to 1–32767
(μs).
S3 + 8: Upper limit of input temperature change. Range: -32168–32767. Temperature
upper limit > Temperature lower limit.
