Application macros 115PID control macroThis macro provides parameter settings for closed-loop control systems such aspressure control, flow control, etc. Control can also be switched to speed controlusing a digital input. To enable the macro, set the value of parameter 9902 APPLICMACRO to 6 (PID CONTROL).For the parameter default values, see section Default values with different macros onpage 180. If you use other than the default connections presented below, see sectionI/O terminals on page 53.Note: The default I/O connections described below are applicable to firmware version5.050 or later. For the default values in earlier firmware versions, see Revision A ofthis user’s manual.Note: Parameter 2108 START INHIBIT must remain in the default setting 0 (OFF).
