More Information

Overview Manuals Motor & Feedback Plug-in Configuration Current & Supply Matching Application
  • Match the complete DDS02.1-W025-D identity, not only the DDS02.1 housing
  • Apply the documented 25 A / 25 A peak / continuous allocation
  • Verify Digital Servo Feedback, DIAX supply capacity and the approved software configuration

DDS02.1-W025-D is a Bosch Rexroth/Indramat DIAX02 DDS Drive Controller Basic Unit 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: 25 A / 25 A. It uses Digital Servo Feedback; command-interface and firmware functions depend on separately fitted modules.

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 DDS02.1-W025-D 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.

  • Use only a motor with Digital Servo Feedback
  • Match the motor feedback cable, connector and software-module motor data
  • Prove feedback direction and motor phasing at low load before production motion
  • Identify the installed command-interface plug-in module and its slot
  • Keep the axis software module with its matching firmware and parameter set
  • Do not infer command-interface compatibility from the basic-unit designation
  • Validate the 25 A / 25 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
  • Textile machinery axes
  • Printing machinery axes
  • Packaging machinery 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.
When is DDS02.1-W025-D preferable to DDS03.1-W030-D for a small axis?
Choose it when the approved motor and duty require the DDS02.1 mechanical platform and a full 25 A continuous capability. DDS03.1-W030-D is narrower but its published continuous limits are lower, so cabinet width alone is not a valid substitution criterion.
Does DDS02.1-W025-D accept a resolver-feedback motor?
No. The D feedback code identifies Digital Servo Feedback. A resolver motor requires a drive/controller configuration explicitly documented for resolver feedback; do not treat the motor connector as proof of compatibility.
What must be moved with the axis when DDS02.1-W025-D is replaced?
Retain the correct software module and its parameter set for the motor and machine axis. Confirm that the firmware, parameter data and plug-in modules belong to this axis before fitting them to the replacement basic unit.
Why can DDS02.1-W025-D power up but not accept the machine command?
The D designation defines feedback, not the command interface. Check the installed command-interface plug-in module, its slot, controller wiring, enable chain and the matching software-module configuration.
Can DDS02.1-W025-D be installed far from the DIAX supply unit?
Placement must follow the documented DIAX arrangement. Keep higher-demand controllers closest to the supply unit, verify DC-bus and control-voltage loading, and do not extend internal connections outside the approved cabinet topology.
Why can a DDS02.1-W025-D axis lose position immediately after a motor change?
Confirm that the replacement motor actually uses Digital Servo Feedback, that its feedback cable and pinout are correct, and that the motor/feedback parameters in the software module match the installed motor.
What should be checked before reusing a stored DDS02.1-W025-D?
Inspect the cooling path, connector damage and plug-in slots, then verify the exact type plate, software module, command-interface module and motor feedback before connecting the DC bus. A clean low-load direction and feedback test should precede production motion.
