Speed Calculation


To determine the speed of the roller, you must know the diameter of your roller tube and the gear reduction ratio of the motor roller in order to calculate the speed based upon the Motor RPM you have selected with SPEED DIP Switches 1 thru 4 and CONFIG DIP Switch 1.

Speed Code and Gear Ratio Table

The Speed Code for any Pulseroller is a 2 digit number found on the label at the cable end of the unit.

Once you know your Speed Code, you can then reference these charts to get the corresponding Gear Ratio

Speed Code Gear Reduction Ratio
15 45
20 33
35 55/3
45 15
60 11
95 75/11

The formula for calculating the speed in m/s is:

For example, from the above chart, a 60 speed code roller has a gear ration of 11. With a 48.6 mm tube diameter running at 5800 RPM the calculation is:
