42 Control macrosPID control macroPID control macro is suitable for the control of a process variable, for example, thepipe pressure in a drive-controlled pumping system.You can activate the macro from the Control macros view, or by setting parameter96.04 Macro select to value PID.The macro is optimized for the standard drive variant ACS380-04xS and theconfigured drive variant ACS380-04xC +L538. Default control connections for PID control macroThis connection diagram is valid for the standard drive variant ACS380-04xS and theconfigured drive variant ACS380-04xC +L538 (with the PID control macro selected).Notes:Terminal sizes: 0.14 mm² … 1.5 mm²Terminals DescriptionDigital I/O connectionsAux. +24 V DC, max 200 mAAux. voltage output commonDigital input commonStop (0) / Start (1)Internal setpoint sel1 1)Internal setpoint sel2 1)Constant speed / freq selection 2)Ramp pair selectionReady runDigital output auxiliary voltageDigital input/output commonAnalog I/OExternal PID ref 3)Analog input circuit commonActual PID feedback 4)Analog input circuit commonOutput frequency (0...20 mA)Analog output circuit commonSignal cable shield (screen)Ref. voltage +10 V DCSafe torque off (STO)Safe torque off.
