New inverters for demanding applications

Mitsubishi Electric has introduced the latest FR-E800 inverter series which offers multiple networks and high performance predictive mainte- nance through AI and built-in corro- sive gas alert. Oliver Endres, Strategic Product Manager Drives, Factory Automation

tion circuit. In conjunction with Mitsubishi Electric’s drives AI diagnostic technology, this helps to reduce overall downtime by allowing early identification and resolution of fault causes without the need for specialist skills. To maintain safety and productivity, the inverters achieve SIL2/ PLd and SIL3/ PLe. Safety functionality is featured as standard without the need for an encoder and includes safe torque off (STO), safe stop 1 (SS1), safe brake control (SBC) and safe speed monitor (SSM). Enhanced, customised control is provided by the built-in PLC functionality which is configured via FR‑Configurator2 software. Multiple inverters can be controlled by a single master, removing the cost of an external PLC. The FR-E800’s autotune function can be used for surface permanent magnet (SPM), interior permanent magnet (IPM) and in future, synchronous reluctance motors. Control modes including closed loop vector control (with encoder), real sensor-less vector control (without encoder), and positioning without sensors are supported. With scalable power for application diversity, the FR‑E800 series offers output from 0.1 kW to 7.5 kW extending to 22 kW (normal duty) / 30 kW (light duty), supporting 200 V single/three phase, 400 and 575 V three-phase.

EMEA at Mitsubishi Electric Europe BV, says this highly flexible, compact inverter series with multiple built-in net- works, including TSN (Time Sensitive Networking), has been developed to support the needs of smart factories. Industries such as machine building and automotive, as well as food & beverages, life sciences and water treat- ment will benefit from the control capabilities. Using AI, the FR-E800 reduces downtime with its extended predictive maintenance functions and fea- tures the world’s first (according to Mitsubishi Electric research, September 2019) corrosive gas alert system (patent pending). The inverters also achieve high per- formance control of induction and permanent magnet motors to Safety Integrity Level (SIL) 3/PLe. The FR-E800 series offers increased flexibility by in- corporating multiple communications without the need for option cards. Major industrial Ethernet networks are supported as standard, including CC-Link IE TSN. Net- work flexibility is also increased with two Ethernet ports which support line, ring and star topologies. Enhancing predictive maintenance, the inverters fea- ture the industry’s first corrosive gas environment detec- As part of its Digital Enterprise SPS Dialogue, Siemens introduced Analyse MyDrives Edge, its first edge application for drives. This development demonstrates how edge computing can make Sinamics drive systems more intelligent and offers users and machine builders additional benefits. Analyse MyDrives Edge is being launched with ba- sic functionalities similar to the proven Mindsphere ap- plication of Analyse MyDrives, and will be enhanced with intelligent features based on high-frequency data exchange. The edge application thus allows users of machines and industry applications to perform complex Data exchange between drives and the edge

maintenance. This minimises downtime and reduces the consumption of resources. With the Drive System Framework, Siemens offers the broad framework that allows users to connect the Sinamics drive systems to the Industrial Edge platform. In addition to pure connectivity, the Drive System Framework allows the management of the drive systems connected to the edge platform. For example, machine builders and users can change parameters or perform firmware updates. In future it should also be possible to configure the simulation model, that is, the digital twin of the drive system in the machine. By connecting Sinamics frequency converters to the Industrial Edge platform, Siemens is helping to pave the way for new business models. With intelligent drive technology, machine builders can, for example, provide user-specific application solutions and digital services, or can guarantee the availability of a machine by contract.

The new edge application for drives allows users of machines and industry applications to access and analyse data already collected in the drive.

analyses of data already collected in the drive. Machine learning and AI algorithms on which the edge application is based identify patterns and detect anomalies and their causes, pro- viding timely indications of any required machine
