Synchronisation of a multi-motor speed control system
Abstract
Purpose
The purpose of this research is to compare an industrial ethernet based network (PROFINET Class 1) with a traditional fieldbus network (PROFIBUS).
Design/methodology/approach
Two sets of identical motors were used in the experimental set-up. The speed synchronisation of a lead and follower motors was compared using both PROFINET Class 1 and a PROFIBUS DP network. The level of synchronising achievable was used as a measure of performance for each network.
Findings
It was found that PROFIBUS DP produces a better performance for set point and load changes than PROFINET Class 1 network.
Research limitations/implications
PROFINET Class 2 and higher could not be used in the experiment due to availability of equipment and funding.
Practical implications
This research provides a comparative study of two very popular industrial networks. The results can be used as reference by industry for selection of industrial networks.
Originality/value
The paper provides a manufacturer independent practical comparison of two industrial networks. The application area of speed synchronisation is demanding, and should inform the user on the performance and limitation of industrial networks.
