More Information

Overview Manuals SERCOS Integration Feedback Selection Current & Supply Matching Application
  • Match the complete DDS03.2-W050-BE12-01-FW identity, not only the DDS03.2 housing
  • Apply the documented 50 A / 20 A peak / continuous allocation
  • Verify Digital Servo Feedback and Resolver Feedback, DIAX supply capacity and the approved software configuration

DDS03.2-W050-BE12-01-FW is a Bosch Rexroth/Indramat DIAX03 Compact DDS Configured Drive Controller for modular DIAX motion-control systems.

The air-cooled controller uses a 300 V DC bus and has the same documented peak and continuous allocation: 50 A / 20 A. It combines Digital Servo Feedback and Resolver Feedback with a SERCOS interface; function ID 12, version 01; firmware ordered separately.

Before selection or replacement, verify the complete type code, DIAX supply-unit capacity, motor feedback, software module or firmware, command interface, cabinet cooling and approved machine parameter set.

Availability, condition, price, and shipping time for DDS03.2-W050-BE12-01-FW are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Preserve SERCOS ring order, optical direction, address and cycle configuration
  • Match function ID 12, version 01 and the separately ordered firmware release
  • Inspect fiber connectors and bend radius before network phase-up
  • Select the feedback cable and parameters for digital servo or resolver feedback
  • Do not treat the B feedback code as automatic motor compatibility
  • Verify feedback direction and commutation before applying production torque
  • Validate the 50 A / 20 A peak / continuous allocation against the real motion cycle
  • Confirm DIAX supply-unit capacity, DC-bus stability and simultaneous axis demand
  • Keep the documented cooling path clear and place the highest-output controller nearest the supply unit
  • Compact SERCOS robotic axes
  • SERCOS printing-machine auxiliary axes
  • SERCOS packaging-machine indexing axes

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is DDS03.2-W050-BE12-01-FW not interchangeable with DDS02.2-W050-BE12-01-FW?
Both share a 50 A peak class and BE12 identity, but the compact DDS03.2 version is published at 20 A continuous while DDS02.2-W050 is 50 A continuous. Housing, thermal capacity and axis duty differ.
Can the existing software module be transferred to a replacement DDS03.2-W050-BE12-01-FW?
Only after confirming that its firmware release, parameter set and configured functions match the replacement hardware, motor, feedback and SERCOS application. Record the module identity and parameters before removal, and do not reuse it until any fault involving overvoltage, contamination or module damage has been excluded.
What must match when ordering a spare DDS03.2-W050-BE12-01-FW?
Match the complete type code, B feedback hardware, E SERCOS interface, function ID 12, version 01 and the separately ordered firmware release. Also confirm the software module and motor cable.
Why can DDS03.2-W050-BE12-01-FW communicate but report invalid feedback?
The SERCOS interface and motor feedback are separate functions. Verify whether the motor uses digital servo or resolver feedback, then check the corresponding cable, connector and parameter set.
Can the SERCOS fiber pair from another compact drive be reused for DDS03.2-W050-BE12-01-FW?
Only if its type, length, connectors and condition meet the documented topology. Preserve transmit/receive direction, ring order and bend radius, and clean the connectors before phase-up.
Why can DDS03.2-W050-BE12-01-FW fault during repeated indexing?
Check whether repeated acceleration exceeds the 20 A continuous duty, then review DC-bus sag, DIAX supply capacity, motor data and compact-unit cooling.
What distinguishes a firmware problem from a SERCOS wiring problem on DDS03.2-W050-BE12-01-FW?
An open optical path points first to fiber routing, power or connectors; a closed ring that will not reach the operating phase points to address, telegram, function/firmware or parameter compatibility. Use both ring and drive diagnostics.
