Very informative video. I am currently programming/debugging a machine where I work at that has AC motors controlled by a PF525 VFD, in which they "rotate" the part towards the operator on 2 identical assemblies put together. We are swapping out the current 843E encoders for 847B incremental encoders. We found out that if a load (customer part) is fully loaded into assembly 1 and only partially loaded into assembly 2 (part lengths can vary), assembly 1 rotates faster than assembly 2. Once that weight is removed, they both run at the same velocity again. Any videos on position feedback control with a 525? We are planning on upgrading to the 527 using the MAG instruction if this does not work, in which this video will help out tremendously.

@@matthewkoester5145 It will go away if you change the acceleration and decel, also once you change to a servo control with the PF 527 then that should act better as a servo

@@ShaneWelcher I agree. Correct me if I'm wrong, but even with the wired 847B encoder for both of the 525 drives, that would be less accurate than those encoders with the 527 drives. From what I understand, the MAG instruction that the 527 allows would basically "force" assembly 2 to move at the same acceleration and speed as assembly 1, therefore solving our current issue.

@matthewkoester5145 I would wire each encoder to the drive it goes to. The PF 527 is made for that the PF525 can use the encoders just compare the parameter files

Hello Shane, you have a video about axis servo conversion configuration on position rotary?

[@ShaneWelcher]

A few yes, and a few coming in the future. Check my channel for the word "servo"
