Super slow velocity issues....

Also after reviewing the thread again and what Tommy said, review your homing setup. Here's mine See

Running a 7i76e

Thanks Rod. I increased the STEPLEN value and I was able to make slow movements. However, this one axis is not as smooth as the other axes at slow speeds so it seems like there is more options for tuning. Below are my settings before increasing the STEPLEN.

DIRSETUP = 1000
DIRHOLD = 5000
STEPLEN = 500
STEPSPACE = 4500

If I increase the STEPLEN, do any of the other corresponding variables need to change accordingly? I'm using a Gecko G202. www.geckodrive.com/g202.html

Any suggested values appreciated. Thanks

Unless the settings are limiting your maximum speed there's usually no reason not to use longer step timings
in addition, long direction setup and hold times have very minimal effect on performance so

DIRSETUP = 20000
DIRHOLD = 20000
STEPLEN = 5000
STEPSPACE = 5000

is a good starting point that will work with almost all drives.


Note the this will limit you to 100 KHz maximum step rate
