REX-F REX-F REX-F General The F series controller provides precise control with high accuracy of.% full scale and short sampling time of. second. ewly developed and unique logic, rilliant PID control and Enhanced utotuning, have been introduced to achieve excellent control. The F series controller is ideal for the application that requires tight tolerance. Features High accuracy with short sampling time rilliant PID Enhanced autotuning Multi-memory area : Up to sets of SVs are available High accuracy with short sampling time The F series controller provides precise control at high accuracy of.% full scale and short sampling time of. second. F with /ºC resolution is also available. rilliant PID rilliant PID combines stable control with quick response. On the conventional PID control, there is a conflict between control stability and quick response; response to set point change might be compromised when stability is improved, and stability might be compromised when quick response to SV change is achieved The rilliant PID retains optimum PID values for stability while you can choose control response types among "Fast", "medium", and "Slow". Please set "Fast" response type when quick response is necessary. "Slow" type is appropriate to avoid overshooting. Enhanced autotuning Enhanced autotuning settles PID values without overshooting. It seeks for PID values by making oscillation artificially below the set point value when T bias is set up. ewly developed logic is adopted. [Conventional utotuning] SV [Enhanced utotuning] SV Time T bias Time SV Fast Slow Medium Time Response to the SV change Multi-memory area The F series has memory areas *. Each memory area can store the set value, proportional band, integral time, derivative time, response parameter, and alarm set value. You can change all of these values at one time by digital communication, digital or RE key on the front panel. ar-graph Display The two -segment LED display units show various process data, while the and the deviation status are displayed on the bar-graph display unit. The resolution is segments for REX-F and segments for REX-F/REX-F.
