Position Type Pid Control - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Position type PID control

S.PIDP
RnPCPU
RnCPU RnENCPU
(Process)
Performs position type PID operation. The instruction performs the following processing steps: SV setting, tracking, gain (Kp)
operation, PID operation, deviation check, and control mode determination. Depending on the operation result up to the mode
determination processing, the instruction decides next processing: variation rate & upper/lower limiter and output conversion,
or alarm clear and output conversion.
