Product Description:

The AX2010-AS servo drive is manufactured by Beckhoff as part of the AX Digital Servo Drives series. Designed for multi-axis motion platforms, it converts DC bus energy into controlled three-phase output for synchronous or asynchronous motors used in material handling, packaging, and pick-and-place modules. Its role in industrial automation is to regulate speed, position, and torque while exchanging status and command data with the central TwinCAT controller over EtherCAT. This arrangement supports coordinated axis behavior in machines where synchronized motion and fast response are required.

At the power stage, the drive can deliver a continuous phase current of 10 A rms and sustain brief demands up to 20 A rms for dynamic acceleration profiles. Its digital regulator closes the torque loop with a cycle time of 62.5 µs, and the measured output current form factor is 1.01, indicating that ripple is nearly identical to the fundamental rms value. During nominal operation, the module converts switching losses into 90 W of heat, and the voltage drop across the power transistors is 5 V, a parameter to consider when sizing the DC link. These operating characteristics help the drive maintain stable motor control during rapid load changes and repeated start-stop cycles.

Additional limits define braking and energy return functions. The dedicated brake transistor supplies up to 2 A to an external holding brake, while surplus DC link energy is dissipated through an internal resistor rated at 200 W or, when heavier regeneration is expected, through a 33 Ω add-on resistor. Inductive loads between 4 mH and 25 mH are allowed, protecting the output stage from overcurrent during commutation. Standby losses stay at 15 W and the control electronics draw a 24 VDC safety-relay feed. With a rated installed load of 7 kVA, the drive interfaces to analog speed commands via a 10 V setpoint input and presents 20 kΩ of input resistance to analog ground, which helps avoid loading the upstream control signal.
