Cam switch

  • Menu: 4.5.3

Description

The cam switch function simulates a mechanical cam switch. A cam switch can be used to control actuators or machine sequences during a motion sequence.

A cam switch consists of several cam tracks. Each cam track is assigned a binary switching signal. A cam track is divided into cam windows. A cam window is a value range within which the switching signal of the cam track assumes a certain, defined value.

The cam switch function can be used with the following inverters from SEW‑EURODRIVE:

  • MOVIDRIVE® modular single-axis module
  • MOVIDRIVE® system
  • MOVIDRIVE® technology

A total of 16 cam windows can be defined for these inverters, each of which can be assigned to 4 cam tracks. Each cam track generates a binary switching signal that is set as soon as the actual position is within one of the assigned cam windows. The cam tracks are processed with a cycle time of 500 µs. The switching signal can be output at a digital output or on a process data bit.
