With the AF1000 variable frequency drive (VFD), this company has introduced a cost-effective solution for basic drive applications across industries, including conveyor systems, pumps and fans. The VFD is fully integrated into the TwinCAT automation system via EtherCAT, providing the familiar commissioning convenience and built-in diagnostics found in Beckhoff’s well-established servo drive technology. The AF1000 VFD is available in two different versions: one for a single-phase supply of 240 V AC with a power range of 0.37 kW (0.5 HP) to 1.5 kW (2 HP), and one for a three-phase supply up to 480 V AC with a power range of 0.37 kW (0.5 HP) to 5.5 kW (7 HP). Despite its compact dimensions and gap-free installation, the AF1000 manages to incorporate an integrated control power supply, DC link capacitors, and a ballast circuit. The control voltage is generated by the integrated power supply from the DC link. Both VFD versions are available in a single-axis module or as a highly cost-effective 2-axis module that also reduces cabinet space requirements. Supported motor types include synchronous servomotors, as well as asynchronous and reluctance motors without feedback operated in UF mode or with vector control. The AF1000 VFD is commissioned using TwinCAT Drive Manager 2. — Beckhoff Automation LLC, Savage, Minn.
