Pid Control Macro; Default I/O Connections - ABB ACS310 User Manual

PID Control macro

This macro provides parameter settings for closed-loop control systems such as
pressure control, flow control, etc. Control can also be switched to speed control
using a digital input. To enable the macro, set the value of parameter
MACRO to 6 (PID CONTROL).
For the parameter default values, see section
page 151. If you use other than the default connections presented below, see section
on page 49.
