SEW‑Eurodrive expands MOVI‑C modular automation system for decentralized solutions

LinkedIn +

SEW‑Eurodrive has added further components for decentralized installation to its MOVI‑C modular automation system. The new MOVI‑C modular automation system gives customers optimum access to a wide range of drive electronics components – from application inverters to modular servo inverters. 

MOVIMOT advanced is reportedly an all-rounder that complements the current MOVI‑C products in terms of functionality and consistency and increases the range of possible applications for SEW-Eurodrive’s decentralized drive technology. By integrating an energy-efficient asynchronous motor from the DRN.. range with the new decentralized inverter from the MOVI‑C modular automation system, the decentralized drive unit reportedly achieves maximum system efficiency IES2 to IEC 61800-9-2. According to the company, the integrated digital interface ensures quick, easy and convenient startup, even with an extremely wide range of gearmotor options. Encoder or sensor signals can be evaluated without additional installation work. MOVIMOT advanced can be combined with all standard gear units in series 7 and 9 for versatile and flexible use. As with other MOVI‑C products, integration into various automation topologies is possible with any standard means of communication.

SEW-Eurodrive says that it based the further development of its decentralized product portfolio on its MOVI‑C modular automation system. It claims that MOVIMOT flexible enables the decentralized inverter to be installed close to the motor in the customer’s system. Users can opt for a synchronous or asynchronous motor. MOVIMOT flexible is available in two versions. The MMF3. version can be fitted with options such as a load disconnector (with or without integrated line protection), an M12 engineering interface or with preparation for mounting an operator panel. A key switch with feedback contact can also be integrated. The current configuration of the decentralized inverter (size 1) can supply nominal output currents of 2.0, 2.5 and 3.2A as well as 4.0 and 5.5A for 0.55 to 3.0kW performance classes (depending on motor type). Additional performance classes are in the pipeline for the end of 2021. SEW-Eurodrive says that digital motor integration means users need just a single cable to connect MOVIMOT flexibly to the drive. The intelligent, digital connection using a standardized hybrid cable makes it possible to supply power and transmit data between the decentralized inverter and the motor. As long as the motor is equipped with the MOVILINK DDI digital data interface, electronic nameplate information and brake/diagnostic data are transmitted directly to the inverter for easy startup.

MOVIMOT performance is SEW-Eurodrive’s product for precision and flexibility, which meets the requirements of IE5, the highest energy efficiency rating for a motor to IEC TS 60034-30-2. The company says that MOVIMOT performance can easily be combined with standard drives and brakes, and that encoder or sensor signals can be evaluated without additional installation work. MOVIMOT performance can be combined with all standard gear units in series 7 and 9. The drive unit can also be combined with SEW-Eurodrive’s servo gear units. Integration into various automation topologies is claimed to be possible with any standard means of communication. The optional DynaStop electrodynamic deceleration function can in many cases replace a mechanical brake, thus cutting costs and minimizing wear.

SEW-Eurodrive says its MOVIGEAR classic drive unit combines a gear unit and motor in a single housing and can be combined intelligently with an inverter installed close to the motor or in the control cabinet. The company claims that this ensures an ideal level of flexibility to suit users’ specific system situations:

  • Integrated drive unit consisting of a permanent-magnet synchronous motor and a gear unit
  • 4-3.0kW available in three gear unit sizes
  • Motor energy efficiency class IE5 to IEC TS 60034-30-2

The matching inverters are part of the MOVI‑C modular automation system. The MOVIGEAR classic drive unit can be connected to the new MOVITRAC advanced standard inverter, the new MOVIMOT flexible decentralized inverter and the MOVIDRIVE modular, MOVIDRIVE system or MOVIDRIVE technology application inverters. MOVIGEAR classic is also available in the new design for use in wet areas. The company claims that this version is particularly suitable for applications in areas that are subject to regular cleaning or wet lubrication, and sensitive areas such as those in the food and beverage industries.

SEW-Eurodrive says that MOVIGEAR performance is a highly integrated drive that complements the existing products in terms of functions and consistency and extends the range of possible applications for the firm’s decentralized drive technology. Its digital interface means no additional installation is required for the transfer of the electronic nameplate and various sensor signals between the motor and the inverter. Communication takes place from a higher-level controller via fieldbus interfaces, such as PROFINET IO, EtherNet/IP and Modbus TCP, as well as integrated, digital inputs and outputs. The company claims that this makes MOVIGEAR performance the perfect choice for dynamic conveyor applications. The new drive unit features a compact design and high overload capacity. It exceeds the requirements for the highest motor energy efficiency class IE5 to IEC TS 60034-30-2 and the maximum system efficiency to IEC 61800-9-2. A wet-area design is in the pipeline.

In addition to the drives with the MOVI‑C Field Controller standard and advanced, SEW‑Eurodrive offers motion controllers suitable for specific applications. The firm says that the MOVI‑C Field Controller can be operated on virtually all standard industrial fieldbus systems (PROFINET, EtherNet/IPT Modbus TCP). As an EtherCAT/SBusPLUS master, the MOVI‑C Field Controller controls drive axes in the DSI communication variant and other EtherCAT stations. The housing reportedly offers a high degree of protection, so the controller can be used flexibly in the field without needing an additional control cabinet. If hybrid cables are used, it is also possible to minimize wiring work in the subordinate drive axes, thus reducing costs. Up to 16 drive axes can be controlled and the optimized startup and diagnostics have reduced the level of engineering work required.
