Issue:
How to setup basic S-Flex PID control?

Product Line:
Altivar Machines, S-Flex

Environment:
Series E units with BYP feature

Cause:
Requires PID control in AUTO, but no PID control in HAND

Resolution:
Search other FAQs for details on ATV212 PID settings.  This FAQ addresses the control concept.  The settings listed are changes from the S-Flex factory defaults.

Option 1 = PID control in both HAND and AUTO
F360 = 1(VIA) or 2(VIB) for the analog feedback signal
FMOd = 3 for HMI setpoint adjustment when in AUTO
F207 = 3 for HMI setpoint adjustment when in HAND

Option 2 = PID control in AUTO, HMI speed reference in HAND
F360 = 1(VIA) for the analog feedback signal
Add a potentiometer to PP-VIB-CC
FMOd = 2(VIB) for PID setpoint adjustment when in AUTO
Remove the wire from DOC-14 to VFD terminal R and add a jumper wire between VFD terminals R - RES
F110 = 1 for always active run permissive
F112 = 14 for PID deactivate when in HAND

The potentiometer modification for Option 2 is required because an HMI PID setpoint and an HMI HAND speed reference will conflict with each other.  Changing one changes the other.
