Hi all,
I need to calculate servo drive ratio for a lifting manipulator which is driving on some rails.
I have a Lenze gearbox with ratio 25.294 and a gear where 1 revolution is approximately 250mm in travel distance. d*π.

If i have read your picuteres correct you have a wheel wiht 25 teeth and the size of each tooth is 8 so the travel distance or rotary to linear transform will be:

NoTeeth * u = 25 * 8 = 200mm.

Which unit to use depends on your measurement unit set up on your axis configuration, but it is standart mm.

The gear ratio seems to be an aproximate number of a 3-stage gear box.
Knowing that usually at least 1 prime number is involved the precise ratio should be 430:17.
If possible, please confirm this with Lenze.

The configuration in mapp Motion would look like this:

Hi Tobias,
Thanks you for explanation.
My ratio/travel distance was calculated d x π (79,58 x π).

Hi Martin,
Certanly I will check with Lenze, becuse I am also used to gear ratios in fractions and not decimal numbers.
I don’t use mapp motion. How can I calculate or where can I add this 200mm to ratio?
