Ch ap te r 2 Co n tro l Reg is te r2 - 2 92_2.9 Automatic PID Calculation Feature (Support TKV1.06/TU V4.18 and above)2.9.1 Feature DescriptionAs the set value (SV) being changed, the PID parameters would be calculated automatically based on the relationbetween two set points after performed auto-tuning twice.1. After auto-tuning two set points, the SV slope of alinear function would be calculated based on thechanges of the waveform parameters between twopoints.2. When the SVs being changed, the corresponding PIDparameters would be calculated according to thecalculated slope.2.9.2 Setup InstructionsFollow the below steps to set up (take channel 1 for example):Step 1: Set the first set value (SV) to adjust.CR Page CR# Description Setting ValueAll pages 4 The target value User-definedStep 2: Set the current point for auto-tuning.CR Page CR# Description Setting ValueAutomatic PID CalculationSetup Page (Page7) 11 The current set point forauto-tuning.

And the PIDparameters would be output differently according to each SV.
