AX2070-AS

AX2070-AS is a Beckhoff servo drive in the AX Digital Servo Drives series. It provides an output current of 80 Arms at 400 VAC for supplying a connected motor, while its output-current form is 1.01. The output stage operates with an 8 kHz clock to control power switching. Its rated installed load is 50 kVA, and an 80 AT branch-circuit fuse provides overcurrent protection. The residual voltage drop is 5 V.

The analog input has a resistance of 20 kOhm and a resolution of 1.25 mV, allowing the drive to detect small changes in an analog command signal. The analog output has a resistance of 2.2 kOhm and 10-bit resolution, providing a digitally stepped analog monitoring or control signal. The safety relay operates at 24 VDC for integration with the machine safety circuit.

The drive supports 6 kW of continuous regenerative power for handling energy returned during motor deceleration. A 10 Ohm external regenerative resistor dissipates excess regenerated energy. Power dissipation is 700 W at rated current, which must be considered when sizing enclosure cooling, while quiescent dissipation is 40 W when the drive is energized without delivering rated output. The unit weighs 21 kg.
