Issue:
PID control setup on ATV21 and ATV212 drives?

Product Line:
Altivar ATV21 and ATV212, S-Flex enclosed.

Environment:
All

Cause:
Setting up PID control on the ATV21 and ATV212 drives.

Resolution:

1. Press the mode button until you see AUF
2. Arrow down to F------ and press enter
3. Find F360 and press enter choose your PID feedback assignment and to activate your PID function

• 1 for VIA
• 2 for VIB

• Set to 3 if you want to use the up and down arrows as your set point.
• Set to 1 for VIA or 2 for VIB if you want your analog input to be your set point.

Please note: it is not a good idea to set up to set your PID feedback F360 to 1 VIA and your set point  FNOD to 1 VIA.

Basic setup for a 4-20mA signal input for PID feedback would be:
F201=20%  (4mA)
F202=0
F203=100%  (20mA)
F204= 60hz
F360= 1 (enable PID and feedback is VIA 4 to 20mA)
FNOD= 3  (up and down arrows are your set point.

Optional settings:
F362=PID proportional gain
F363= PID integral gain
F380 = 1 for Reverse acting (0 = deactivated)
