Beckhoff’s economy drive system is a coordinated platform of servomotors, servo drives, and variable frequency drives for compact, cost-efficient machine concepts. The AX1000 economy servo drive has been extended to include an additional three-phase variant rated at 12 A. It now covers the rated current range from 3.4 to 12 A, while in the single-phase range it is available with currents from 1.65 to 6.9 A. One notable aspect is the high packing density: The power supply, DC link capacitors, and braking circuit are fully integrated, despite the extremely compact dimensions. The housing is made of robust plastic, which reduces weight and material costs. The devices can be installed next to each other in the control cabinet without minimum distances having to be maintained between the drives.
Frequency drive and braking resistors
The AF1000 economy variable frequency drive is also available in a new three-phase variant rated at 5.5 kW, providing a cost-optimized solution for basic drive applications such as conveyor systems, pumps, or fans. The series covers the power range with single-phase supply from 0.37 to 1.5 kW, as well as with three-phase supply from 0.75 to 5.5 kW. It offers a scalable solution for a wide range of applications, not only with the single-axis devices typical of this segment, but also with the very cost-efficient double-axis devices. Beckhoff is also able to supply suitable accessories including external braking resistors and mains filters for the economy drive system.
The AX2090-BW10-xxxx braking resistors are available in different variants for devices with single-phase and three-phase supply, as well as different power ratings. This ensures that the braking resistors are optimally adapted to the application. In addition, the high-quality AX2090-NF1x-xxxx mains filters ensure excellent interference suppression for the economy devices. When the components are combined, they meet industry standards up to category C2 in accordance with EN 61800-3.
