Page 7: Speed Compensation
Digitronic Digital Cam Switch Unit Automationsanlagen GmbH CamCon DC33 2.1. Speed Compensation Each mechanical switch component (e.g. shield, magnetic valve) has a delay time, i.e. the time between the start signal and the actual switching of the contacts. In processes where positioning is executed on a moving system, this can cause problems. - Page 8 Digitronic Digital Cam Switch Unit Automationsanlagen GmbH CamCon DC33 A small example in figures was designed to eludicate: Supposing the drive cylinder with the measuring system has a circumference of 360mm, so that one millimeter of the circumference corresponds to exactly one angle degree of the measuring system.

Page 9: Measuring Delay Time For Speed Compensation
Digitronic Digital Cam Switch Unit Automationsanlagen GmbH CamCon DC33 2.1.1. Measuring delay time for Speed Compensation Several ways of measuring delay time of a relay or valve are available. 2.1.1.1. Measuring delay time through actual differences First the switch-ON point of a valve or relay is programmed. We assume that the programmed switch point lies at 200 degrees in this case. -

Page 12: 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 DC33. The SSI interface is a common interface for absolute single and multiturn encoders. The CamCon supplies the measuring system with 24Volt via this interface. -
