Product Description:

The AX5112-0000-0202 is a single-axis drive module from Beckhoff’s AX Digital Servo Drives series. It is intended to control synchronous or induction motors in automated machinery, supplying regulated power and collecting real-time feedback so that position, speed, and torque loops stay aligned with the machine controller. This arrangement supports accurate motion in packaging systems, handling equipment, and other automated installations that rely on coordinated axis control. By integrating power electronics and high-speed I/O into one housing, the unit streamlines cabinet layouts and supports straightforward integration in distributed motion systems.

During operation, the drive draws power from a three-phase line and can deliver an apparent power of 8.3 kVA at 400 V. Its continuous motor feed is supported by a nominal output current of 12 A, while short acceleration bursts can reach a peak of 26 A. Energy is buffered in a DC link that holds 1175 µF of capacitance and can rise to 875 VDC before protective shutdown. Regenerated energy from overhauling loads is dissipated internally, and the brake resistor has a momentary absorption capability of 26 kW. Conversion losses amount to 160 W under rated load and are removed by the integrated cooling channel. The drive connects to field wiring through one power channel, accepts eight digital inputs for local interlocks, and occupies 232 mm of cabinet depth.

The control section exchanges position and status data every 250 µs, matching rapid cycle times in modern PLCs and helping the axis respond quickly to command changes. External brake choppers may be added when regenerative demands exceed the internal limit; in that case, the unit can route up to 23.5 kW into a resistor network no smaller than 30 Ω. A width of 185 mm permits side-by-side mounting with other AX modules, which helps conserve cabinet space in multi-axis installations. The housing also supports compact layouts where several motion components must fit within a limited enclosure footprint.

Error Code Beckhoff Diagnostic Text Typical Cause(s) Quick Fix / Next Step
FC0B Over-current error motor, short-circuit detection Phase-to-phase short, stalled rotor, wiring error, or severely oversized load Remove power, inspect motor leads & phasing, verify motor free rotation; correct wiring then reset drive
F703 Feedback “general”: Feedback error Generic encoder/feedback fault—always occurs with a causal sub-error Read accompanying errors, check encoder cables & grounding, reseat connector; reset via S-0-0099
F707 Feedback “general”: Lost feedback No feedback voltage sensed (loose plug, broken sense line, wrong parameters) Reseat feedback connector, ohm-check sense pair, verify parameter set; reset
F152 Channel Errors (dual-axis drives) One channel flags a subordinate error in the opposite axis Examine the other channel’s log for root cause, clear that error first, then reset both axes
F326 Additional position-deviation monitoring Position error outside stable window (mechanical overload, poor tuning) Inspect mechanics for binding/backlash, refine tuning; adjust P-0-0551 limit if appropriate; reset
F852 One-cable feedback: Position error limit exceeded Excess following error from overload, encoder slip or wrong gear ratio Reduce load/inertia mismatch, verify encoder coupling, raise position error limit only if justified; reset
F146 Build-drive-system: Failed (internal error) Generic initialization fault—firmware or hardware inconsistency Power-cycle 24 V & mains, reload correct firmware; if recurring, contact Beckhoff support
FCD3 Over-speed error Commanded or runaway speed > parameter S-0-0113 Check motion program, mechanical coupling; raise limit only if motor spec allows; reset
F012 Firmware-download: Flash error Flash write failed during firmware update Retry with verified firmware file, stable 24 V; if persistent, drive or CF card may need replacement
F191 Internal communication: SPI (control ↔ front card) Data-bus integrity issue—improper card seating, corrupted firmware Reseat front card, check for bent pins, update firmware; power-cycle and monitor
