Specification of a pulse constant

The pulse constant of the connected speed sensor or pulse encoder is usually noted in the
technical data sheet of the respective sensor. If "kg/m" was selected for the belt load, you
must specify the pulse constant in "Pulses per meter". If the belt load is displayed in "lbs/ft",
you must specify the pulse constant in "Pulses per foot".
If the sensor is mounted on the axis of a guide pulley, use the following equation to calculate
the pulse constant:
Pulse constant per meter = (Pulses per revolution) / (π x d)
Pulses per revolution: see sensor data sheet
π = 3.1416
d = diameter of guide pulley in meters
The inputs are completed using the save button (diskette symbol).
Then move on to the "Zero calibration" using → Zero calibration (Page 53).
