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.
One of the most substantial advantages has to do with the hybrid cabling between the inverters themselves. Simply connecting ACOPOSremote 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.
Because the inverter is separate from the motor, the user is free to select the actuator best suited to his drive solution. This type of installation is particularly well suited for the increasingly prevalent linear and torque motors. It prevents the properties of the motor from being negatively influenced, and the maximum possible dynamics remain available throughout.
ACOPOSremote 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 ACOPOSremote – the ideal enhancement for modular drive solutions that require the highest levels of performance and flexibility.
ACOPOSremote 8CVI inverters are usually connected via a hybrid cable by simply arranging the individual modules in a line structure. This type of arrangement places a number of demands on the hybrid cable. In addition to its main tasks of supplying energy and handling network communication, other aspects such as connector technology, manageability and flex radius also need to be taken into consideration. The sum of these demands results in a practical limit to the cable diameter, which in turn limits the maximum current available to supply the ACOPOSremote 8CVI inverters in this line structure.
In applications where this maximum current is insufficient, the necessary power must be provided in another way, made available to a remote location on-site and then redistributed from there. This is where the 8CVE remote connection box comes in.
Like the ACOPOSremote, the 8CVE remote connection box is designed with IP65 protection so it can be mounted directly on the machine. The robust housing makes it ideal for use in tough environments and gives the user the freedom to position the device wherever it best serves the application at hand.
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 use remote servo drive technology.
The 8CVE remote connection box comes equipped with four hybrid cable outlets, which allows the power to be divided between up to four ACOPOSremote 8CVI inverter line structures.
Classic wiring solutions have also been taken into consideration. The connections necessary for the STO signals (Safe Torque Off) are also included on the 8CVE remote connection box and directly affect the ACOPOSremote 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.
