The fully digital 4800 / 4900 DC speed controllers are powerful modular devices. 

They have the following functions and characteristics:

• High-quality actual value processing for precision control systems and very large adjustment ranges.
• Fieldbus connection permitting flexible incorporation in the overall control system
• Master frequency connection for symmetric operation with and without cascading permitting high precision but simple setpoint selection
• Resolver, incremental encoder or DC tachometer as feedback in an economical solution for your application

The common user interface and the Lenze controller interface permit trouble-free drive mix in complex systems, making these devices the ideal drives for many applications.  A large variety of external control and regulating functions can be outsourced to the controller so that complex drive systems can be realised in a compact, simple and economical form.
