i750

The i750 cabinet servo inverter provides everything for precise and dynamic motion control in complex multi-axis applications. Advanced safety functions and One Cable Technology reduce wiring and control complexity. Intelligent data-based functions and IIoT enable innovative motion control concepts.
As a single or double axis, the i750 cabinet with a matching supplier fits seamlessly into the Lenze automation system. The strengths of the inverter become apparent in numerous applications in combination with Lenze controllers and the FAST Application Software Toolbox. The scalable range of hardware, software, engineering services, and digital services supports the realization of integrated automation systems from the cloud to the drive shaft.
As a power extension of the i750 cabinet servo inverter in the range of 22 ... 110 kW, the i950 cabinet servo inverter can be used.
