The process entails rotating the encoder by a number of complete revolutions (e.g.
5
complete revolutions) then measuring the distance traveled by the cable.
For example, if the cable travels 1000
mm in 5 complete revolutions of the encoder, the
Tacho step must theoretically be set to 40
μm.
Tacho step = 1000 mm / (5000 × 5) = 0.04 mm = 40 μm
By performing a number of complete revolutions, the risk of error is reduced and the
Tacho step can be set more accurately.
Useful formulas for setting the Tacho step depending on the configuration of
your production line:
Tacho step (µm) =
Tacho perimeter
(mm)
x 1000
Tacho resolution
Number of Tacho steps for 1 mm =
1000
Tacho step (mm)
Tacho Division =
Number of Tacho steps
for
1 mm
x 2
Theoretical horizontal resolution
Actual horizontal resolution (points/mm) =
Number of

■ Object speed
In the case of a product run at a constant speed, you enter the speed value in millimeters
per second.
If you use tacho mode, you have to enter the value of the maximum speed of the product
run.
