    Syncronising Controller MCO 350 Operating 5. Appendix Instructions 5.3. Glossary of Key Terms Master-Slave It means that a signal is taken from a master drive. The signal is then used to control a second “slave“ drive that follows the master. The master drive does not have to be a drive; it can be any given part of a power transmission system.
  • Page 97 Syncronising Controller MCO 350 Operating Instructions 5. Appendix Track Error The synchronising controller of the slave drive uses the master drive signal and the gear ratio to calculate a reference position value for the slave drive. The deviation of the feedback position from the calculated position is known as the track error.

Appendix Instructions Illustration 5.2: Addition of the Cycle Times In this case, the same application is realised by means of incorporating a virtual master. Although the way that the reference value is introduced at the first belt is analogous, the value is used to set the virtual master signals.
