Controlling the roller speed

To calculate the roller speed based on the motor speed selected on DIP switch switches 1 to 5, the diameter of the respective roller as well as the gear unit reduction ratio of the motor roller must be known.

The following table shows the speed classes of the ECR motor rollers and their respective reduction ratios.
