A compact drive for low power servo and stepper applications

25 March 2010

In addition to controlling stepper motors, the new version of the ACOPOSmicro from B&R now also offers support for servo motors. This new addition to the ACOPOSmicro product family allows users to integrate different drive types for the first time. The flexible drive architecture enables a quick changeover from stepper to servo and vice versa. Users benefit from the ability to combine both technologies in a single application.

Despite its small dimensions, the ACOPOSmicro also supports up to two axes with performance levels of 500W each from one module. The new drive requires a base surface of less than 50 cm² per axis, enabling multi-axis applications to be implemented with minimal space and wiring requirements.

The ACOPOSmicro product family can be used in a nominal voltage range from 18 Vdc to 80 Vdc for low power applications. State-of-the-art semiconductors ensure a low amount of heat loss – this eliminates the need for expensive cooling  that can be difficult to implement. Furthermore, the intelligent power supply module with a network connection offers completely new options for machine and system diagnostics.

In addition to the Safe Torque Off function and trigger inputs, the servo version of the ACOPOSmicro also has a 24 VDC output that can, for example, be used to drive external brakes. Additional optional modules make it possible to adapt to customer-specific requirements at any time - without taking up more space.
