Application Macro Pid Control - ABB ACS 400 User Manual

Application Macro PID Control

This macro is intended for use with different closed-loop control systems such as pressure control,
flow control, etc.
The value of parameter 9902 is 6 (
Input signals
• Start/stop (DI1,5)
• Analog reference (AI1)
• Actual value (AI2)
• Control location selection (DI2)
• Constant speed (DI3)
• Run enable (DI4)
Note!
* Constant speed is not considered while in PID control (PID).
Note! Parameter 2107

Output signals
• An. output AO: Frequency
• Relay output 1: Fault
• Relay output 2: Running
EXT1 (Manual) or EXT2 (PID) reference: 0...10 V
Reference voltage 10 VDC
Actual signal; 0...20 mA (PID)
Output frequency 0...20 mA <=> 0...50 Hz
+24 VDC
Start/Stop: Activate to start ACS 400 (Manual).
EXT1/EXT2 Selection: Activate to select PID control
Constant speed 1: not used if PID control*
Run enable: deactivation always stops ACS 400
Start/Stop: Activate to start ACS 400 (PID)
Relay output 1, programmable
Default operation: Fault => 17 connected to 18
Relay output 2, programmable
Default operation: Running => 20 connected to 22
