Two-Degree-Of-Freedom Pid Control - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Two-degree-of-freedom PID control

S.2PID
RnPCPU RnPCPU
RnCPU RnENCPU
(Process) (Redundant)
This instruction performs two-degree-of-freedom PID control operation (inexact differential). The instruction performs the
following processing steps: SV setting, tracking, gain (Kp) operation, two-degree-of-freedom PID control operation, and
deviation check.
