New dimensions in decentralised drive architecture

21 November 2011

B&R is expanding its range of drives with a series of motor-integrated servo drives with IP65 protection.

It was the next logical step for the company to merge inverters with the motor to create servo actuators that can deliver power directly where it is needed. Configurable modules then become easy-to-connect mechatronic units which saves space in the control cabinet, can cuts costs for logistics and commissioning.

The new system unites all of the important components such as the motor, positioning sensor (encoder), precision gearbox and servo drive into a compact unit. The ACOPOSmulti65m supports the implementation of modular machine concepts, making it possible to efficiently design optimised manufacturing strategies. "With the new servo actuator, we are continuing on the path to decentralised motion control," said Alois Holzleitner, business unit manager of Motion at B&R. "We now offer the entire drive spectrum – from variable frequency drives and multi-axis servo drives to decentralised drive solutions - from a single source."

By combining the latest IGBT technology and optimised motor types, users profit from the resulting maximum performance. With three different sizes, the servo actuators cover the entire spectrum, with a torque range of 1.8 to 10.5 Nm and a power range of 500 W to 2 kW. For applications that demand more power, an optional fan assembly can be retrofitted for a performance boost of up to 100%.

The ACOPOSmulti65m is compatible with the entire ACOPOS drive series. The new servo actuator can be employed in either a line or tree structure. Networking takes place using POWERLINK.

In addition, it comes equipped with STO (Safe Torque Off) and SS1 safety functions in accordance with SIL 3 or PLe. Additional safety functions such as SLS, SOS, SDI, SLP and many more can be used in combination with openSAFETY and are an integral component of the ACOPOSmulti65m model.
