9.5.8 Controller configurationThe “controller configuration” is automatically carried out during selection of the application relatedmode of operation (Base setup). The factory presets in accordance with the mode of operation arebased on many years of experience, which is suitable for many applications. Under special circum-stances, these can be individually adapted ( Menu group “setting”).Controller Setup The type of control determines the method with which the controlled value behaves incase of a difference between the target and current values. For this, the controltechnology has standard algorithms, which consist of a combination of three methods:Selection P, PID:• P control (Proportional component, proportion of the absolute deviation)• I control (Integral component, proportion of the sum of all deviations)• D control (Differential component, proportion of the last difference)Display for operation with two control circuits:“1.Controller type” for control circuit 1“2.Controller type” for control circuit 2PType of controlWith pure P controllers (controller type P), the following described settings do not have any function.If needed, the most suitable combination for the respective control system can be determined from theseproportions.The control configuration (KP, KI, KD, TI) is identical for both control circuits in operation with two control circuits.Fine adjustment is possible for each control circuit by the separate “Pband” setting.Controller Setup P-component = reaction timeSetting range: 0 - 200 %smaller = more slowlybigger = faster50 %KPController Setup I-component = accuracy, correction timeSetting range: 0 - 200 %bigger = fastersmaller = more slowly50 %KIController Setup D-componentMore “D-component” causes more stability by a clean actual value signal with shortercorrection timesBy a actual value signal with a superposition should be done to attitude without “D-component” → 0 %Setting range: 0 - 200 %value smaller = less “D-component”value higher = more “D-component”50 %KDController Setup Integration time = correction timeSetting range: 0 - 200 %smaller = fasterbigger = more slowly0 %TIOperating Instructions Fcontrol – model series FKDM25/32AM-C ProgrammingL-BAL-E214-GB 1446 Index 002 Part.-No.41/99
