Machine-mounted inverter

B anB and R Acoposmulti65d R’s Acoposmulti65 inverters are designed with IP65 protection, which makes it possible to attach them directly to the machine. The switching cabinet therefore only contains the power supply modules and the necessary electromechanical components. This makes it much easier to implement modular machine architectures.

Drive solutions that are matched to the application are a basic requirement for keeping machines and systems competitive. Inverters must be taken out of the switching cabinet and placed in the direct vicinity of the machine. This allows configurable modules to become mechatronic units that can be easily connected, which reportedly reduces the delivery times, installation space and commissioning times. For this reason, directly integrating inverters in the immediate environment of the actuator - without the need for additional accompanying measures - represents one of the configurations available. B and R developed the Acoposmulti65 inverter for applications where the drive is mounted directly on the machine.

Another advantage has to do with the hybrid cabling between the inverters themselves. Simply stringing together Acoposmulti65 drive modules in a line - the "daisy chain" wiring scheme - results in a clear and flexible machine architecture where energy is simply passed from one drive module to the next.

In addition to the proven wired safety functions STO (Safe Torque Off) and SS1 (Safe Operational Stop 1 time-monitored), network-based Acoposmulti65 variants, based on openSafety, will also be available in the future as an option. This will allow users to access the following functions that have already been certified for Acoposmulti: STO, SBC, SOS, SS1, SS2, SLS, SMS, SLI, SDI and SLP.

The B&R Acoposmulti65 inverter for applications where the drive is mounted directly on the machine makes flexible machine configurations possible.
