Distributed drive system

Being able to directly integrate drive components into the machine is a fundamental requirement for modular machine manufacturing. B&R has designed the ACOPOSremote distributed drive system to meet this requirement, allowing implementation of drive solutions that are completely optimized to the application at hand.

Drive solutions that are tailored exactly to the application are essential to keeping machines and systems competitive. That's why directly integrating inverters in the immediate environment of the actuator – without the need for additional accompanying measures – is the perfect solution. With the new ACOPOSremote drive system, B&R is now accommodating this wish. This architecture offers many different advantages when it comes to machine configuration.

The ideal topology

One of the most substantial advantages has to do with the hybrid cabling between the inverters themselves. Simply connecting ACOPOSmulti65 drive modules together in a line – the "daisy chain" wiring scheme – results in an uncomplicated and flexible machine architecture where energy is passed from one drive module to the next.

Integrated modularity

All modules in the ACOPOSmulti65 product line are designed with IP65 protection, which makes it possible to mount them directly on the machine. The control cabinet then only has to contain the power supply, high-powered inverter modules and other necessary electrical switching devices. The result is a much easier implementation of modular machine architectures. When optional machine functions are required, they can easily be connected – with the requisite dimensioning of the power supply – to the machine's main line using hybrid cables.

Free motor selection

Because the inverter is separate from the motor, the user is free to select the actuator best suited to his drive solution. This is probably the best type of installation, especially for the linear and torque motors that are becoming more and more prevalent. It prevents the properties of the motor from being negatively influenced, and the maximum possible dynamics remain available throughout.

Homogeneous and compatible

ACOPOSmulti65 drive systems offer the well-known functionality of the ACOPOSmulti drive family and can therefore be integrated homogeneously into a drive solution.

Optimal machine and system configurations are based on the ACOPOSmulti65 – the ideal enhancement for modular drive solutions that require the highest levels of performance and flexibility.

8CVE remote connection box

ACOPOSmulti65 8CVI inverters are usually connected using a hybrid cable by simply arranging the individual modules in a line structure. The demands placed on using a hybrid cable in this way are many. In addition to its main tasks of supplying energy and handling network communication, other aspects such as connector technology, manageability and bending radius also need to be taken into consideration. The sum of these demands results in a reasonable maximum cable diameter, but it ultimately limits the available maximum current for supplying the ACOPOSmulti65 8CVI inverters in this line structure.

In applications where this maximum current is not sufficient, the necessary power must be provided in another way, made available to a remote location on-site and then redistributed from there. It is for these situations that the 8CVE remote connection box has been developed.

Robust and flexible

Like the ACOPOmulti65, the 8CVE remote connection box is designed with IP65 protection so it can be mounted directly on the machine. Its robust housing makes it ideal for use in tough environmental conditions. This allows the user to flexibly adapt the device's location to the requirements of the respective application.

Separate cable routing means more free space

Because the power supply, the 24 V supply, the safety technology (STO signals) and the POWERLINK network are wired separately, the 8CVE remote connection box can provide a considerable amount of power directly to the machine (up to 30 kW).

Not only that, but it's also possible to use standard cables to implement alternative solutions such as transferring energy using slip rings. This provides the user with the flexibility to work with conventional connector technology while still being able to operate the remote servo drive technology.

Extensive connection options

The 8CVE remote connection box comes equipped with four hybrid cable outlets, which allows the power to be divided between up to four ACOPOSmulti65 8CVI inverter line structures.

Classic wiring solutions also haven't been neglected. The connections necessary for the STO signals (Safe Torque Off) are also included on the 8CVE remote connection box and directly affect the ACOPOSmulti65 8CVI inverters connected to the hybrid cable outlets.

In addition, the 8CVE remote connection box is equipped with two local I/O connections – another example of exemplary support for modular machine concepts.
