Figure 7-9 Speed calibration (belt loaded)
Activate the procedure when the belt marking is passed by using the "Start calibration"
command. Make sure that material is distributed uniformly on the belt at this time. In the
optimum case, the belt load should be close to the nominal load during the measurement.
Stop the calibration as soon as the belt has carried out the defined number of revolutions
and the marking has passed the defined point for the last time.
The average belt load factor is subsequently output as a percentage, and the measured
speed in % of the speed with the belt empty. Import the parameters by clicking on "Apply
new speed".
As an alternative to the belt marking and manual sending of commands, you can connect a
belt revolution sensor (e.g. a proximity switch) to digital input DI.1. When assigning the
parameters for the digital inputs, you must then assign the "Trigger belt revolution recording"
function to DI.1. Pulses are then counted at input DI.1 according to the parameterized
number of belt revolutions, and an exact trigger point is thus achieved.
