- 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.
