ACS550-02/U2 User’s Manual 105Application macrosMotor Potentiometer macroThis macro provides a cost-effective interface for PLCs that vary the speed of themotor using only digital signals. To enable, set the value of parameter 9902 to4 (MOTOR POT ).Connection example:Input signals Output signals Jumper setting• Start, stop and direction (DI1,2)• Reference up/down (DI3,4)• Constant speed selection (DI5)• Run enable (DI6)• Analog output AO1: Speed• Analog output AO2: Current• Relay output 1: Ready• Relay output 2: Running• Relay output 3: Fault (-1)or1 SCR2 AI13 AGND4 10V5 AI26 AGND7 AO18 AO29 AGND10 24V11 GND12 DCOM13 DI114 DI215 DI316 DI417 DI518 DI619 RO1C20 RO1A21 RO1B22 RO2C23 RO2A24 RO2B25 RO3C26 RO3A27 RO3BNot usedReference voltage 10 V DCMotor output speed: 0 …20 mAReference up: Activation increases the reference1Reference down: Activation decreases the reference 1Relay output 1, programmableDefault operation:Relay output 2, programmableDefault operation:Relay output 3, programmableDefault operation:Output current: 0 …20 mAReady =>19 connected to 21Running =>22 connected to 24Fault (-1) =>25 connected to 27Analog input circuit commonNot usedAnalog output circuit commonAuxiliary voltage output +24 V DCAuxiliary voltage output commonDigital input common for allSignal cable shield (screen)Analog input circuit commonNote 1.
