Application macros

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
to 6 (PID
CONTROL).
For the parameter default values, see section
Default values with different macros
. If you use other than the default connections presented below, see
section
.
Note:
Parameter
START INHIBIT must remain in the default setting 0 (OFF).
