AX5106-0000-0020 by Beckhoff

The AX5106-0000-0020 is a digital servo drive produced by Beckhoff within the AX Digital Servo Drives series. This unit converts three-phase mains power into a controlled, pulse-width-modulated output that commands synchronous or induction motors in packaging machines, gantries, and material-handling axes. It supplies regulated current, integrates braking energy management, and offers eight onboard digital inputs for direct field signals.

With a single-phase 230 V source, the inverter draws an apparent power of 1.8 kVA, while a 400 V three-phase source increases the available apparent power to 4.2 kVA. During three-phase operation, the rated motor current is 6 A, and short acceleration bursts are supported up to 13 A. The shared DC bus may rise to 875 VDC, so cable insulation and creepage distances must accommodate this potential. A brake output delivers 2.2 A to external resistors, while internal losses are limited to 85 W during continuous operation. The converter has a width of 185 mm and a depth of 232 mm, simplifying side-by-side mounting in a 300 mm cabinet section.

The internal DC link stores energy in a capacitor bank rated at 235 µF, smoothing regenerated power before it is either dissipated or returned to adjacent drives. In stand-alone mode, the built-in chopper can absorb up to 150 W of braking heat. For higher-inertia loads that must stop quickly, an external network rated for 15 kW can be attached, provided its resistance is not lower than 47 Ω. The drive has a nominal current of 4.5 A when connected to a single-phase supply. Its heat sink is 317.70 mm high and helps keep peak apparent power within cabinet thermal limits. Natural convection carries heat away from the drive without requiring additional cooling hardware.
