Your choice for cost-sensitive and high performance applications.



The ULC AC-Servo Drive by BRUNNER is a compact, intelligent servo controller for driving synchronous and asynchronous Motors up to 1 kW. It is targeting all applications where price-performance is key. The integrated mains filter, power supply and I/O interfaces ensures minimum cabling effort and true plug & play functionality at an unmatched price-performance point.

The integrated field bus interface (EtherCAT® or CANopen®) enables the communication and easy integration with a superordinate control system (e.g. TwinCAT® or CodeSys). Point-to-point positioning or master-slave applications are possible as easy as synchronized multiple axes.

Beside the standard CANopen® operations modes (DS-402) we have optionally integrated our unique active force control mode, that enables a smooth force control for robotic and simulation applications.

BRUNNER has the unrivaled capability to implement client-specific modes or design even a dedicated Drive upon request. Our parameter setting tool „DriveSetup“ enables the easy operation and setup of the drive via USB.
