Ideal drive design doesn't waste its power

The Acoposmulti generation offers the highest degree of efficiency for multi-axis machines that are commonly used in the plastics, packaging, print and textile industries.

Acoposmulti is the logical progression of the successful Acopos series from B and R that meets the demands of users for modern motion control products.

The Acoposmulti generation offers the highest degree of efficiency for multi-axis machines that are commonly used in the plastics, packaging, print and textile industries.

Environmental considerations were also a major motivation in keeping energy consumption low.

Acoposmulti is billed as the ideal drive design that doesn't leave any of its power in the switching cabinet.

Both a feedthrough heatsink with IP65 protection for releasing heat outside the switching cabinet and a "cold plate" variant for connecting to a cooling circulation system (water, oil) are available.

This eliminates the need for fans and climate control units in the switching cabinet.

All power supply modules are able to regenerate power.

Instead of being converted to heat as is usually the case, kinetic energy generated during braking is converted to electrical energy that is regenerated into the power supply system.

The integrated power regeneration system provides an efficient and environmentally friendly solution for avoiding heat build-up in the switching cabinet which is otherwise generated by braking energy.

An additional advantage is that only true power is taken from the power supply.

The "power factor correction" mechanism considerably reduces the connected load and power consumption of the machine (by approximately a factor of 2).

This reduces the requirement for fuse safeguarding and the cross-sections of connections.

Like all other modules in the Acoposmulti series, the power supply module also has a network connection.

This allows all data about power consumption, machine efficiency etc to be recorded and analysed.

This represents a big step in the direction of "intelligent maintenance".

Acoposmulti integrates the 24V supply for drives and even for the PLC, PC or peripherals (optional).

This doesn't just guarantee minimum space requirements; it also ensures predictable machine behaviour when power is lost.

Devices can be connected directly to the common DC bus on the drive and have open-circuit, short-circuit, and overload protection.

In addition to the advantage of the integrated supply, both Ethernet Powerlink and the remote intelligence of the individual servo drives perfectly support the functionality of the controlled standstill.

The connection design couldn't be easier - the installer simply attaches the unit to the mounting plate and fastens with two screws.

This establishes the connections with the power supply module.

In addition to the connection of the DC bus and the 24V, the protective conductor connection is established via the rail system.

Additional grounding measures from module to module are not necessary.

There are a number of new approaches to secure fieldbus systems that are heavily influenced by proprietary standards and long response times.

The Acoposmulti drive system is different.

This system is based on Ethernet Powerlink Safety.

Safety in the Acoposmulti drive system comprises the following function taken from Cat 3, EN954-1: uncontrolled and controlled stops; secure stop and operation halt; secure limited step measurement and secure limited absolute position; secure limited speed; and secure direction of rotation Basic functions like the secure restart inhibit or output for the motor holding brake (both according to Cat 3, EN954-1) are part of the standard delivery.
