Drives with centrally controlled servo motors are commonly used for end-of-line packaging. However, in applications with large inertia or long movement distances – for example palletizing, stabilizing, or handling – they are usually not mandatory. Decentralized drive solutions, for example, with controlled asynchronous motors, are an efficient, and economical alternative in this context. Depending on the system type and application, cost benefits of up to 50% are possible.

In the packaging industry, conventional servo drives are used in the majority of cases, or more precisely, drive solutions with centrally controlled synchronous servo motors. The complex and expensive technology has its justification in primary and secondary packaging, as exact positioning and high dynamics are required. In many end-of-line packaging applications, however, synchronous servo drive systems are not absolutely necessary. Due to the high masses and high inertia, the process requirements there are less dynamic. Additionally, many servo functions such as synchronization of several axes are rarely needed. Controlled asynchronous drive systems are often more efficient and significantly more economical – in particular if they are operated with decentralized frequency inverters.

Cost benefits of up to 50% in end-of-line packaging

Asynchronous drive systems are suitable for a wide range of applications in end-of-line packaging – be it handling, palletizing, or transport security. Due to their specific characteristics, they are an ideal solution for the specialized requirements in the last stage of packaging processes – heavy loads, high forces, long movement distances, slow movements, dynamic load changes – and represent an efficient and economical alternative to drives with centrally controlled synchronous servo motors. The use of decentralized VFDs with “closed-loop control” also results in enormous cost savings for the packaging industry. Depending on the system type and application, cost benefits of up to 50% are possible.

Asynchronous motors offer decisive advantages

Asynchronous motors achieve similar kinematic properties as synchronous servo motors and, due to their higher internal inertia, ensure better regulation and motion control than conventional servo solutions, which must be adjusted to the respective application via large gear ratios. Furthermore, they enable the highest process stability in end-of-line packaging, reduce vibrations, and the risk of damaging the load or packaging machine. Another advantage for the packaging industry: asynchronous motors are available everywhere in a wide range, are easy to maintain, and can be combined with different types of gear units and frequency inverters.

Decentralized drive technology for the packaging industry

For users in the packaging sector, decentralization of drive technology means faster commissioning, as well as simplified maintenance and repair processes. For example, they can be considerably reduced on the software side with factory pre-configurations. With a modular concept, the drive also remains extremely flexible, as changes to the system architecture can be made at any time without large structural modifications, and additional drives can be easily added later without changes to the control cabinet. This results in reduced costs, more efficiency, and easy scalability and expandability.

Efficient, economic drive solutions for end-of-line packaging

Low procurement costs, constructive freedom in machine design, faster commissioning, and simplified maintenance and repair processes: asynchronous motors with decentrally controlled variable frequency drives and encoder feedback via absolute or incremental encoders enable highly economic, precise positioning applications and dynamic movement of large and heavy packaging units. This makes this technology a real alternative for application fields such as end-of-line packaging, where heavy loads and high forces are the norm. Depending on the system type and application, the savings can amount to up to 50%.
