28 n SPS SHOW REVIEW February 2026 www.drivesncontrols.com In addition to its new i950 multi-drive system (covered in our January issue), Lenze was showcasing several other recent developments at SPS. One of these was the IE3-efficiency, inverteroptimised m650-F motor, based on the company’s new m500 platform. The m650-F is said to be two sizes smaller than conventional three-phase motors. With a low moment of inertia and high overload capacity, it is dynamic and energyefficient. Gearboxes can be mounted directly on the motor using a central thread, while the space-saving decentralised i550 and i650 motec VSDs (see below) can be mounted on the terminal base. Options include spring-applied brakes (for emergency stops from high speeds) and incremental encoders integrated into the end shield. The decentralised i650 motec VSDs expand Lenze’s portfolio in wall- and motor-mounting formats. They have built-in logic PLCs, table positioning, and IO-Link masters that deliver operating data directly from the drive, thus supporting IIoT applications and predictive maintenance. A built-in regenerative module feeds braking energy back into the mains, enhancing efficiency. The drives achieve 300% overload torque from a standstill, and can reach full load without any problems and without motor feedback. This allows the system to be designed for continuous operation. It delivers the required power immediately. When used with IE5/IE6 synchronous motors, the result is an efficient motor-drive system that saves space and reduces carbon footprints. With its Fast application and Codesys-based PLC Designer 4.1, Lenze is offering software tools for the simple, efficient creation of modular software architectures. Machine variants can be configured flexibly, regardless of the hardware used. This shortens time-to-market and reduces sources of error, according to the company. Commissioning is said to be quick and straightforward thanks to guided routines, autotuning and pre-configured applications. Automated engineering workflows reduce manual work steps and shorten set-up times, so that even small batch sizes can be produced economically and flexibly. End-to-end data access from the drive to the cloud creates transparency and opens up new potential for digital services, according to Lenze. Support for communications standards such as EtherCat, Profinet and OPC UA, simplifies integration into existing industrial environments. www.lenze.com Inverter-optimised motors are ‘two sizes smaller’ than others Lenze’s compact M650-F motors deliver low moments of inertia and high overload capacities Gravity-loaded axes in robotics applications need to be safe. At sps, mayr power transmission demonstrated how the next generation of its Roba topstop safety brakes make this possible in smart environments. The compatible Roba brake-checker module provides continuous monitoring of the brakes. When combined with mayr’s Roba gateway, these elements produce data for machine maintenance, digital twins, and smart production environments. In production facilities, or robots with gravityloaded axes, it is essential to protect people and materials. Mayr’s failsafe safety brakes (applied in a de-energised condition) can hold loads in position reliably and prevent uncontrolled movements in the event of power outages or emergency stops. They are placed between the motor and the output and can be retrofitted to existing installations. The braking system is supplied as an independent, compact module. O-rings ensure reliable sealing against dust and moisture, with the brakes offering IP66 protection. The vertical axes remain secure even if the drive is dismantled for maintenance or transport. May’s Roba brake-checker module monitors the safety brakes without needing any extra sensors. It recognises the brake’s condition based on changes in current and voltage. It can detect critical parameters, such as switching times, coil temperatures, and functional reserves. When used in conjunction with the Roba gateway module, the brake-checker module becomes network-compatible, allowing the collected data to be integrated into remote maintenance systems, or digital twins to be created. Mayr also offers a validation aid that simplifies dimensioning in accordance with DIN EN ISO 13849-1. A structured checklist includes all of the relevant information about safety principles and enables a standardised assessment of the brakes. www.mayr.com/en Brakes ensure safety of vertical axes and offer intelligent monitoring option The combination of mayr’s safety brakes, with its brake-checker and network modules, allows continuous monitoring and the generation of data for digital twins
