Product Description:

The AX2040-B200-0001 is a digital servo drive manufactured by Beckhoff as part of the AX Digital Servo Drives series. It sits between the motion controller and a three-phase servomotor, shaping the current delivered from the DC link so that commanded position, speed, and torque are followed precisely in automated machinery. This arrangement lets the controller close motion loops while the drive supplies regulated motor power during axis movement. The unit is intended for axes that need precise response during repeated starts, stops, and speed changes.

To handle dynamic duty cycles, the drive delivers a continuous current of 40 Arms and can supply 80 A for short acceleration bursts. Current is modulated at an output stage clock of 8 kHz, which helps limit ripple and switching losses. The internal DC link is supported by an auxiliary logic supply of 24 V DC that preserves parameter memory and fieldbus communication through the Lightbus interface. The rated installed load is 30 kVA, which indicates the maximum apparent power drawn from the cabinet supply. Analog command channels present an input resistance of 20 kΩ, while each digital input sinks 7 mA and the transistor outputs source 10 mA. The brake-test and brake-release contacts are rated for 500 mA, and the current form factor of 1.01 indicates a nearly sinusoidal motor waveform. Under rated load, the residual voltage drop toward the motor terminals is held to 5 V.

Thermal performance is anchored by a power loss of 400 W at rated current, with a quiescent dissipation of only 40 W when the axis is enabled but idle. These losses must be removed by the control cabinet airflow to keep semiconductor junctions within acceptable limits during continuous operation. The housing has a width of 250 mm and adds 19.5 kg to the panel, so the cabinet structure must support both the installed mass and the cooling clearance around the unit. Those dimensions influence panel spacing and mounting layout in multi-axis cabinets.
