More Information

Overview Manuals Motor & Feedback Plug-in Configuration Current & Supply Matching Application
  • Match the complete DDS03.1-W050-D identity, not only the DDS03.1 housing
  • Apply the documented 50 A / 20 A peak / continuous allocation
  • Verify Digital Servo Feedback, DIAX supply capacity and the approved software configuration

DDS03.1-W050-D is a Bosch Rexroth/Indramat DIAX02 Compact 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: 50 A / 20 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 DDS03.1-W050-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 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 robotic axes
  • Printing-machine auxiliary axes
  • 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 DDS03.1-W050-D not a thermal equivalent of DDS02.1-W050-D?
The compact DDS03.1-W050-D is published at 50 A peak / 20 A continuous, while DDS02.1-W050-D is 50 A / 40 A. An axis that fits the peak value can still exceed the compact unit's continuous duty.
Can DDS03.1-W050-D be chosen only to save cabinet width?
No. Verify continuous torque, repetition rate, heat dissipation, cable space and the DIAX supply before choosing the 70 mm housing. Width is only one selection factor.
Why can DDS03.1-W050-D current-limit during a long constant-speed load?
Its continuous allocation is 20 A even though the peak class is 50 A. Check the motor load, friction, switching/parameter setup and cooling rather than raising the current limit.
What must match when a DDS03.1-W050-D software module is replaced?
Match firmware, motor identity, Digital Servo Feedback data, command-interface option and the saved machine-axis parameters. The module is the carrier of firmware and operating data.
Can DDS03.1-W050-D operate a motor with resolver feedback?
No. The D code is tied to Digital Servo Feedback. Select a resolver-capable configuration rather than adapting the feedback cable.
Why can DDS03.1-W050-D produce direction or position errors after maintenance?
Check feedback and motor phase connections, encoder direction, transferred parameters and command polarity. Prove low-load direction before restoring normal motion.
What should be reviewed before replacing DDS03.1-W030-D with DDS03.1-W050-D?
Recheck motor current, DIAX supply capacity, protection, wiring, heat and the saved axis limits. The shared compact housing does not make the W030 and W050 duties identical.
