(3) When "degree" is set as the control unit for a rotary axis
When the rotary axis is used, the motor is HG-KR (4194304PLS/rev) and
the reduction ratio of the reduction gear is 3/11.
First, find how many degrees the load (machine) will travel (
motor turns one revolution (AP).

AP (Number of pulses per rotation) = 4194304 [PLS]
 S (Movement amount per rotation)
Substitute this for the above expression (1).
At this time, make calculation with the reduction ratio 3/11 remaining as a
fraction.

2883584 (AP)
=
0.06750 (AL)  1000 (AM)
Thus, AP, AL and AM to be set are as follows.
AP = 2883584 ......[Pr.2]
AL = 67.50000
AM = 1 ...............[Pr.4]
Note): These two examples of settings are only examples. There are
settings other than these examples.
