Page 6: Delay Time Compensation
Digital Cam Switch Unit Digitronic CamCon DC30 Automationsanlagen GmbH 2.1. Delay time compensation Every mechanical switching part (e.g. relays, magnetic valves) possesses a delay time, i.e. between the triggering signal and the actual switching of the contacts passes a certain amount of time. Because of that, problems can arise during procedures in which positionings are carried out in a moved system. - Page 7 Digitronic Digital Cam Switch Unit Automationsanlagen GmbH CamCon DC30 A small numerial example shall serve the illustration: Assuming that the drive roll with the measuring system has a circumference of 360mm, so that one millimeter at the circumference corresponds exactly to one angle degree of the measuring system.

Page 11: The Encoder
The encoder is used for getting the actual position, necessary for the cam controller. Only encoders with an SSI interface can be connected to CamCon DC30. The SSI interface is a common interface for absolute single and multiturn encoders. The CamCon supplies the measuring system with 24Volt via this interface. -
