I found my own answer. I changed Parameter 622, Slip Comp Bandwidth from the default of 10 to a value of 4. That corrected the surging speed problem. ------------------------------ DougPLC ------------------------------

PF755 UNSTABLE SPEED

Posted By DougPLC Jan 15, 2024 08:26:00 PM
Found In Egroup: Drives, Motion Control & Low Voltage Products \ view thread
I am starting up a new PF755 (40HP, HD) which is replacing a 1336 Plus II for the Bowl axis of a 30 yr old horizontal Centrifuge. This axis has a huge 2ft diameter Bowl - lots of inertia but otherwise low resistance to rotation. If it were to coast, with no product, from 1950 rpm it could easily take ...

I need to change the hardware input filter for a faster response in my migrated proogram. I see that the only time I can modify the filter settings is when I start with a new program. Is that defined as one never having been uploaded? What is the best way to migrate my logic, data tables and configuration ...

RE: Merging logic and tags from a few CompactLogix programs

Thanks for taking the time to comment. I had never noticed the Merge feature. I tried it and it seems to have worked pretty well although there were some CPU parameters that I was not sure that I was choosing the correct parameter (going from an L18 to a 5069-L310). I first created a temporary remote ...

TJ is correct. The best thing is probably to download Studio5000ver28 and install it on the same PC. Unlike many programs you can have a number of versions installed simultaneously. Only detail is that you must have a Tech Support contract to download any of the versions. ##HL38

RE: Chemical Feed with Slow Loop

Just a thought - I once saw a guy running a gas blending valve that fed a gas mixture into an engine. He had to provide a very slow change of the ratio of flamable gases so he would keep switching from Manual PID mode to Automatic PID mode. He would let the PID run in Auto for maybe 5 secs out of every ...

Well I guess I'll answer my own question. 300,000 is a fixed value and is not dependant on any external conditions. ##HL40

Summary: Is 300,000 always the limit for datalog samples even if SD card is used Using FTME on a PV+6 ver 6.0 can I log more than 300,000 data points if I use an SD card to increase storage capacity? If yes then how much more and can I also use an SD larger than 2GB? #HL40 #HL40 #FTVME
