Chapter 13 Control Sub Functions
(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.
Reduction
ratio 3/11
M
First, find how many degrees the load (machine) will travel (
S
) when the
motor turns one revolution (AP).
 AP (Number of pulses per rotation) = 4194304 [PLS]
 S
(Movement amount per rotation)
= 360.00000 [degree]

Reduction ratio
= 360.00000

3/11
Substitute this for the above expression (1).
At this time, make calculation with the reduction ratio 3/11 remaining as a
fraction.
AP
=
4194304 [PLS]
S 360.00000 [degree]

3/11
=
4194304 [PLS]  11
360.00000  3
=
46137344
1080.00000
=
2883584
=
2883584 (AP)
67.50000 67.50000(AL) 
1 (AM)
=
2883584 (AP)
0.06750 (AL)  1000 (AM)
Thus, AP, AL and AM to be set are as follows.
AP = 2883584 ……
Pr.2
AP = 2883584 …
Pr.2
AL = 67.50000 ….
Pr.3
or AL = 0.06750 …
Pr.3
AM = 1 ………..….
Pr.4
AM = 1000 …….
Pr.4
Note): These two examples of settings are only examples. There are
settings other than these examples.
