• • Display the conveyor transfer speed
To display the conveyor transfer speed on OPX-2A, set the conveyor gear ratio by
using the formula below:
Conveyor speed
reduction ratio
When the calculated conveyor speed reduction ratio is used, the conveyor transfer
speed is converted as follows.
Conveyor transfer speed
[m/min]
Example:
The pulley diameter is 0.1 m and gear ratio (speed reduction ratio) of the gear head is 20
Conveyor speed reduction ratio =
From the conversion formula, the conveyor speed reduction ratio is calculated as 63.7 in this example. This means
that the "speed reduction ratio" parameter (ID: 2085) is 637, while the "speed reduction ratio digit setting" parameter
(ID: 2086) is 1.
When the speed reduction ratio is 63.7 and the motor rotation speed is 1300 r/min, the conveyor transfer speed is
converted as follows:
Conveyor transfer speed [m/min] =
"20.4" is displayed on the OPX-2A.

All parameters can be set in both the speed control mode and position control mode.
The parameters that can be used vary depending on the control mode.
