WEG's condition monitoring and automation products at SPS 2019

WEG Motor Scan is an easy and cost-effective option for predictive maintenance measures that lead to extended service life and higher plant availability. The gateway, with features highly desired by users, was already in the pipeline when WEG Motor Scan was announced. The gateway enables users to automatically collect data from WEG Motor Scan sensors, eliminating the intermediate step with the mobile app. The gateway complements the existing mobile app and acts as a router that captures all installed sensors within a range of approximately 30m in an industrial environment. Integration of WEG Motor Scan with the gateway creates clear added value through enhanced ease of use and automation. The gateway, consisting of firmware and hardware, will be available from October 2019.

There are some innovations in the CFW family of variable speed drives: the new CFW500 IP66 in frame sizes A and B covers motor power ratings from 250W to 15kW. These variable speed drives can operate over a wide voltage range of 200 to 240V, 380 to 485V or 500 to 600V, and they can be deployed at ambient temperatures from -10degC to +40degC. Their sturdiness and high protection rating make them a good choice for demanding manufacturing environments.

CFW500 range extended

Furthermore, the CFW500 range is extended to frame size F with a rated power range up to 55kW. The new CFW500 operates in the voltage range of 380 to 480V, opening new deployment options for users in the higher power range for a large number of industrial applications - in particular general mechanical engineering for conveying, turning, lifting, pumping and ventilation. The new power class extends the main deployment areas of the CFW500 in small and micro applications. Integrated Safe Torque Off (STO) and Safe Stop 1 (SS1) safety functions give mechanical engineers an economical and flexible option for reducing risks arising from unexpected and unforeseen events. This includes prevention of unintentional machine starts, emergency shutdowns, and controlled stops. Another integrated function is PumpGenius for pump control, which enables precise pressure and/or flow control during the entire process cycle. With a convenient programming wizard, PumpGenius helps to minimise downtime.

The MW500 variable speed drive, designed for decentralised deployment, has also been updated. It is now available for lower power levels in the range of 370W to 2.2kW and is being launched for 380 to 400V mains voltage in frame sizes A and B. A sturdy housing design with protection rating IP66 or NEMA 4X allows the variable speed drives to be mounted directly on the motor terminal box or on the wall using an adapter plate. This eliminates the need for a motor feed cable and switch cabinet, reducing complexity and costs for installation and commissioning. The MW500 can handle a 150 per cent overload for 60s every 10min and can operate at ambient temperatures up to 40degC with wall mounting or 50degC with motor mounting. Designed for decentralised deployment, these variable speed drives can be used for a broad range of applications, such as pumps or fans.

WEG has also expanded its SSW900 series of soft starters. The series was previously available in frame sizes A to D, covering the output current range from 10A to 412A in the wide voltage range of 220 to 575V AC 3-phase. Now frame size E is also available for output currents from 489 to 670A. As high-performance top-end devices with integrated PLC functionality, they provide fully programmable algorithms for regulating induction motors as well as fully flexible torque control. Thanks to soft starting and integrated protection functions, the SSW900 ensures energy-efficient and reliable operation of electric motors. SSW900 is particularly suitable for sectors such as petrochemical, mining, textile, woodworking, plastic processing, metalworking, water/wastewater management, and food & beverage.

The newly developed CWBS series of contactors for safety applications from 9A to 80A conforms to the IEC 60947-5-1 standard regarding mechanically linked contacts and mirror contacts (IEC/EN 60947-4-1). Additionally, WEG is introducing the new CWB125 contactor of the CWB series. It is suitable for a rated operating power of 55kW (AC-3/400V) and a rated operating current of 125A. The modular, user-friendly design enables easy installation and flexible application.
