Highline inverter drive: motion controller

Lenze Americas 8400 HighLine Inverter Drives are designed to act as a motion controller and a frequency inverter. It has integrated point-to-point positioning for up to 15 position destinations, and stores the corresponding travel profiles in the inverter.


Lenze Americas 8400 HighLine Inverter Drives, part of the Lenze L-force 8400 portfolio, is designed for positioning applications, the HighLine model features integrated point-to-point positioning for up to 15 position destinations, and stores the corresponding travel profiles in the inverter. 

“Positioning in motor drive systems used to require a separate motion controller. Most applications don’t require a higher cost servo drive. Dynamic speed, torque and precision motion control can be achieved with a powerful inverter in combination with an asynchronous motor,” said Darrow Hanesian, director of inverter products, Lenze Americas. “Our streamlined HighLine delivers all the cost savings and benefits of combining two drive elements—the motion controller and the frequency inverter — into one.”

The HighLine inverters’ integrated components translate to installation ease, with less cabling and a smaller panel size. Built-in advanced functionality includes linear and S-shaped travel profiles, a touch probe function, and homing selectable from 14 modes. The brake management system reduces wear on service brakes. A 2.5A digital output with integrated spark suppressor directly controls a 24V service brake. Standard features include an integrated brake chopper, switching logic for spring-applied brakes, a plug-in memory module, and CANopen communications on board with baud rate up to 1000 kbit/s. Optional plug-in network communication modules are available for Profibus, EtherCAT, Profinet fieldbuses. HighLine can be supplied with a Safe Torque Off (STO) module that complies with IEC 61508, EN/IEC 62061, and SIL3.

Available in power ranges 0.25-15 kW, HighLine apparently delivers up to 200 percent rated torque. Performance pushes into levels that would previously have required servo technology, with HighLine positioning accuracies of 0.1-0.2 mm at 60 operations (120 movements) per second. Lenze L-force Engineer configuration software offers users an intuitive, graphic interface that facilitates drive parameter setting and configuration. The High-Level Engineer version contains key functions for large scale projects, including establishing network, interconnecting communication and a function block editor.

Lenze’s 8400 HighLine inverter drives excel at controlled movement tasks at a considerably lower price point than servo technology, the company said. Industrial and manufacturing positioning applications might include cut-to-length machinery, rotary indexing tables, palletizers, extruders, hoists, filling systems, conveyors, turntables, gates and dosing pumps, and other motion control tasks. The L-force 8400 is a new range of inverter drives from Lenze. Four models with increasing functionality, theBaseLine, StateLine, HighLine and TopLine, optimize customer sizing, design flexibility, and cost savings. The Lenze 8400 Inverter Drives offer a fully compatible and consistently scaled range of modular drive solutions.
