- Display the conveyor speed
To display the conveyor speed, calculate the conveyor speed reduction ratio by using the formula
below and set to the “speed reduction ratio” parameter.
𝐶
𝑟
=
1
𝐹
=
𝐺
𝑟
𝐷 × 𝜋
Conveyor speed reduction ratio :
𝐶
𝑟
Gearhead reduction ratio :
𝐺
𝑟
Feed rate per motor revolution :
F
Pully diameter :
D[m]
Conveyor speed :
𝐶
𝑠
[m/min]
Motor output shaft rotation speed :
𝑀
𝑠
[𝑟/𝑚𝑖𝑛]
When the calculated conveyor speed reduction ratio is used, the conveyor speed is converted as
follows.
𝐶
𝑠
=
𝑀
𝑠
𝐺
𝑟
Example : the pully diameter is 0.2m and gear ratio of the gearhead is 50
𝐶
𝑟
=
𝐺
𝑟
𝐷 × 𝜋
=
50
0.2 × 𝜋
= 79.6
From the conversion formula, the conveyor speed reduction ratio is calculated as 79.6 in this
example.
Setting the calculated as 79.6 with “speed reduction ratio” and the motor rotation speed is
3000r/min, the conveyor speed is converted as follows:
𝐶
𝑠
=
3000
79.6
= 37.7
Accordingly, “37.7”is shown on the panel.
