PID control macro

This macro provides parameter settings for closed-loop control systems such as
pressure control, flow control, and so on. Control can also be switched to speed
control using a digital input. To enable the macro, set the value of parameter
APPLIC MACRO to 6 (PID CONTROL).
For the parameter default values, see section
macros
see chapter
