High-accuracy PID control is possible by adopting a sophisticated algorithm and floating-point operations.
Higher accuracy is obtained by ultra high-speed computations in a 32µs/loop. For example, a 16-loop control only adds a scan
time of 0.5ms by ensuring minimum impact on the tact time.
The simultaneous multi-point auto-tuning simplifies complex parameter setting.
The high-speed control PI-D*¹ mode and overshoot suppression I-PD*² mode are available for selection according to the intended
application.
By combining with a sequence control, the parameters (Kp, Ti, Td, etc.) can be changed during a PID control execution, thereby
enabling optimum temperature control in each stage including start up, mid-range and convergence. The ability to change the tar-
get value easily enables multi-step temperature control, which was difficult with only temperature controllers. In addition, the
multi-point temperature control enables centralized control of multiple temperature controllers with a single FP-X for unified data
management.
