Chapter 13 Control Sub Functions
(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.
Reduction ratio 7/53

Belt
conveyor
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 (
S
) when
the motor turns one revolution (AP).
AP (Number of pulses per rotation) = 4194304 [PLS]
S
(Movement amount per rotation)
= 135000.0 [
m]
Reduction ratio
= 135000.0 [
m]
7/53
1/3
Substitute this for the above expression (1).
At this time, make calculation with the reduction ratio 7/53
1/3
remaining as a fraction.

Thus, AP, AL and AM
to be set are as follows.
