On some older models with the pulse type encoder I run into issues. It seems like the wheel constantly moves in some position.
I’m thinking about increasing pulses to 3-5 (that needs more turn on the wheel to trigger) and at the same time every 3-5? seconds I’d do a pulse - 1 that way if the wheel itself doesn’t shake a lot it would not disengage.
Any thoughts about this?
Do you guys experience the same?
could yous describe model and year of JD ?
in this video it will be 6120M 2023-2024 series
The encoder is sending a pwm value that it will be impossible to read with ADC converter
but if you check the frequency and his evolution * you can do it
*It means the quantity of modification during time like a do with my virtual turn sensor
I was able to convert it to a % it was a few years old model 6110M with FEMA valve.
(we couldn’t bypass the errors of autotrac though… maybe someone can disable it via a laptop?)
but my scope was showing the exact same output and I decided to use the Pressure input as it has the voltage divider and protection
You need a friendly JD tech with the laptop and a payload file to tell the tractor to shut up about it - not easy to come by, apparently.
From what I know, 30 series are quadrature encoders, newer are variable duty, mostly.
For the code, I saw that I could disable autotrac in the diagnostic menu on a 6430. But I didn’t, in case it would not reactivate later if wanted. If the owner want sell it.
