PROGRAMMING MANUAL 267
Revision 1.0
Example 4
fig. 22
The mechanical system uses a servo motor with a 17-bit absolute encoder.
The mechanical gear ratio of the gearbox is 1:12.24. The mechanical
measurement units must be tenths of an angle degree. Therefore the total
repeat distance for the full turn of the moving part is 3600 tenths of an angle
degree.
With the same procedure as in example 1, we have:
Therefore:
One solution is:
Because the greatest common divisor of Pn202 and Pn203 must be 1, we
get: Pn202 = 17 and Pn203 = 500. Therefore, the parameters are:
To calculate the multiturn limit setting Pn205, we have:
