ACS550-02/U2 User’s Manual 107Application macrosPID Control macroThis macro provides parameter settings for closed-loop control systems such aspressure control, flow control, etc. To enable, set the value of parameter 9902 to6 (PID CONTROL ).Note: Parameter 2108 START INHIBIT must remain in the default setting, 0 ( OFF ).Connection example:Input signals Output signals Jumper setting• Analog reference (AI1)• Actual value (AI2)• Start/stop – hand/PID (DI1, 6)• EXT1/EXT2 selection (DI2)• Constant speed selection (DI3, 4)• Run enable (DI5)• Analog output AO1: Speed• Analog output AO2: Current• Relay output 1: Ready• Relay output 2: Running• Relay output 3: Fault (-1)orNote: Use the following switch-on order:1.
