AX5206-0000-0202 by Beckhoff

The AX5206-0000-0202 is a dual-channel servo drive that Beckhoff supplies within its AX Digital Servo Drives series. It regulates torque and velocity for two three-phase servomotors, allowing machine controllers to coordinate precise motion axes while sharing the unit's common DC link. By converting a fixed 400 VAC supply into controlled pulse-width modulated output, the drive forms a core element in packaging lines, test rigs, and material-handling stations that require synchronized positioning.

Each channel can deliver a continuous three-phase current of 6 A, and together they support a nominal total current of 12 A. For rapid acceleration, the current capacity of each channel rises to 13 A, while the device can momentarily supply a combined 26 A to cover simultaneous peaks. The intermediate circuit is rated for up to 875 VDC, and a DC-link capacitance of 470 µF stabilizes the bus voltage during regenerative events. The internal thermal design limits steady conduction losses to 160 W, and the drive converts 8.3 kVA of apparent power at 400 V in S1 duty. Continuous braking power of up to 90 W is absorbed by onboard resistors, whereas external dissipation requires a brake resistor with a minimum resistance of 47 ? to prevent overcurrent.

Short bursts create higher electrical and thermal loads, so the external brake circuit can handle 15 kW of peak braking power. The integrated resistor tolerates up to 14 kW for brief intervals without exceeding its temperature limits. Cabinet installation is simplified by a width of 92 mm, a depth of 232 mm, and a height of 317.70 mm, permitting dense side-by-side mounting. The enclosure has an IP20 protection rating, so the drive must be installed in a closed control panel that is free from conductive dust. Total power loss, dimensions, and mandatory brake resistor values help determine the ventilation capacity and wiring gauge required for safe continuous operation.
