Integration made easy

Highly compact and highly integrated: The IHD system comprises a backlash-free gearbox, a sophisticated servo motor, a dual motor feedback system for position measurement and a powerful motion controller in a ready-to-use drive solution. Easy integration into your application is supported not only by the drive's central hollow shaft, which is predestined to carry a wide variety of media, but also by our specially developed, user-friendly software solution for simple commissioning – plug and play.


Compatible and predictive

Thanks to thermal optimization of its design, the IHD meets all requirements for high-performance applications in the field of stationary and mobile drive technology. Advanced simulation tools for thermal evaluation of the system have been developed for this purpose. The IHD system has an application processor for future smart applications such as condition monitoring and can be used as a separate platform for customer-specific application programming. The system operates with DC voltages of 24V or 48V. Communication with the machine controller is possible via CANopen, Ethernet and EtherCAT.
