Video: How do you set up PID control on the ATV21 and ATV212 drives?

Issue:
How do you set up PID control on the 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 enable your PID function
  • 1 for VIA
  • 2 for VIB
        4. Set FNOD as your PID set point
  • 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 = disabled)
