TYPICAL WORK CYCLE

During normal machine activity, the DE2020 module will:

• Manage the input power profile, shaping the electrical power

coming from the input, leveling the peaks, and flatten the load

peak on the DC grid.

• Charge the accumulator energy banks and accurately control

the voltage across them.

• Provide additional energy during acceleration phases.

• Handle the kinetic energy obtained from running masses

during their braking phases.

• Provide the system with previously stored energy during

acceleration phases.

• Temporarily withstand DC grid failures or unexpected

disconnections of the DC power supply providing the system

with the necessary energy to bring the machine to a safe state.

DE2020 SYSTEM OVERVIEW

Modes of Operation:

• Power Leveling

In a typical machine cycle, accelerations require peaks of power; the

DE2020 can handle energy using energy storage accumulators in

order to guarantee a performance beyond the nominal power of the

electrical equipment.

• Energy Recovery

Usually while braking, the energy that motors give back to the

system is partially wasted as it is dissipated on the power supply

dynamic braking resistor. With the DE2020 module, this energy

is stored in  the accumulator energy banks, such as the Moog

Additional Bus Capacitor (ABC module) or larger in sizes, in order to

be saved and reused.

• Energy Backup

The DE2020 can use the energy stored in the accumulator energy

banks when the grid is down to ensure safe home movements of the

machine and/or to keep safely controlling critical axes during grid

failures. This feature makes the system more reliable and protected

against issues related to sudden losses of power from the grid.

Silencer® brushless controllers are available in a variety of voltage

and current ratings. All controllers have generous terminal blocks

to facilitate ease of wiring and they are designed for ease of mounting

in a small envelope, requiring minimal space in a cabinet / enclosure.

Silencer drives are compatible with Silencer Series Brushless DC Motors.

Silencer motors are available in sizes 12. 17. 23. 28. 34 and 42 in

standard frames with 1.2 to 4.15 inch diameters.

They offer speeds up to 20.000 rpm and continuous torques ranging from

1.2 to 519 oz-in. Standard options include gearheads, resolvers and encoders.

Features

COMPACT, DIGITAL MULTI–AXIS SERVO DRIVES FOR TOP PERFORMANCE AND

MAXIMUM PRODUCTIVITY

The DM2020 is a state of the art servo drive designed to meet the requirements

of the most challenging machine builders. It unites flexibility, high performance

and simplicity of use. Its  modular design platform permits a high level of

customization to satisfy specific application needs. With its high-performance

control board and software for advanced control, the DM2020 guarantees

speed and faster cycle times, improving efficiency and ensuring maximum

productivity. The multi-axis architecture with a shared power supply unit

reduces the size of the axis module and overall dimensions of the system

by roughly 50% compared to a stand-alone similar configuration.

The DC-Bus is distributed among the axes through internal front panel

connections.

In addition to the shared DC BUS configuration that allows the exchange of

energy among the axes, specific modules are also available.

The capacitive ABC module, for example, increases the exchange of energy

among the different axes of the system, improving the efficiency of the machine.

By connecting external supercapacity modules, the peaks required by the

machine cycle can be delivered independently. By integrating Moog’s DE2020

Energy Management System >, it is possible to control the power absorbed

from the mains during peak times thus limiting the sizing of the system to

the nominal value required by the regular cycle.
