Product Description:

The AX2513-M1 is a single-channel digital servo drive produced by Beckhoff and assigned to the AX Digital Servo Drives series. Designed for medium-power motion axes, the unit interfaces with AC synchronous motors and linear stages to regulate torque, speed, and position in automated machinery. It accepts ±10 V analog command signals as well as fieldbus control, converting them into precise current pulses for the connected motor. By managing both steady-state and dynamic demand, the drive supports accurate positioning while protecting the supply through integrated overload and overvoltage supervision.

The drive’s continuous phase capability is rated at 3 A rms, while transient loads can be handled with a peak of 9 A rms for short acceleration intervals. A fast output stage that switches at 8 kHz minimizes current ripple and improves control loop bandwidth. Protection against DC-link excursions is provided by an overvoltage trip set to 750 V, preventing damage to power semiconductors. The ±10 V analog input has a resolution of 1.25 mV and an input resistance of 20 kΩ, which limits loading on upstream controllers. Under rated current, the drive dissipates 35 W of heat, a value that scales with load inductance, which must stay between the specified 12 mH minimum and 75 mH maximum for stable operation.

For cabinet planning, the housing measures 100 mm in width, 230 mm in height, and 240 mm in depth before connectors, allowing high-density stacking without exceeding the system’s thermal envelope. The supply can deliver up to 12 kVA in S1 duty, and the nearly unity current shape expressed by an output form factor of 1.01 keeps conductor losses low. Standby consumption is limited to 12 W, so auxiliary power demand remains modest when the axis is idle. Because the depth is measured before connectors, rear clearance is still needed for cable bends inside the cabinet.
