Thus, AP, AL and AM to be set are as follows.
AP = 2883584 ......[Pr.2]
AL = 67.50000
AM = 1
Note): These two examples of settings are only examples. There are
(4) When "mm" is set as the control unit for conveyor drive
(calculation including
When the belt conveyor drive is used, the conveyor diameter is 135mm,
the pulley ratio is 1/3, the motor is HG-KR (4194304PLS/rev) and the
reduction ratio of the reduction gear is 7/53.
M
Reduction ratio 7/53
As the travel value of the conveyor is used to exercise control, set "mm"
as the control unit.
First, find how many millimeters the load (machine) will travel (
the motor turns one revolution (AP).
 AP (Number of pulses per rotation) = 4194304 [PLS]
S

Substitute this for the above expression (1).
At this time, make calculation with the reduction ratio 7/53
remaining as a fraction.
