The LANG positioning system LSTEP PCIexpress is a high-resolution stepper motor controller for up to four axes with 2- and 3-phase stepper motors, realised as a PCIexpress plug-in card for the IPC. A user-friendly, automatic controller design based on a few parameters is possible in servo mode. With our free WIN-Commander software, you can comfortably configure and also operate your system. In addition, an oscilloscope function is integrated for analysis purposes.
Communication between the IPC and the controller works via the PCIexpress bus. Using our free API, simple and efficient integration into your software environment is possible. The dynamic microstep operation enables fast positioning processes with high accuracy. The small dimensions of the PCIexpress card allow integration into almost all IPC housings.
You are also welcome to use the industrial PC that we have specially designed for the LSTEP PCIexpress. This impresses with a robust sheet steel housing and with connector cut-outs adapted to the controller.
The integration of control and power amplifiers on a PCI plug-in card enables compact, EMC-proof systems without additional mechanical effort. This solution is therefore particularly suitable for cost sensitive applications. A variety of options enables optimised adaptation to different system requirements while at the same time providing the highest level of operating convenience. The free LANG API allows the integration into your own software environment.
