More Information

Overview Manuals Robot Family Match Voltage Class Axis Output Map Product Applications

Features:

  • MDU-790A identity: ABB links Product ID 3HAC029818-001 to the main drive unit
  • Broad robot scope: documented medium and large IRC5 families use this drive architecture
  • Configuration-specific mapping: voltage and manipulator type govern the power-stage arrangement
DSQC 663 provides the MDU-790A drive platform for a defined ABB IRC5 robot and supply configuration.

Its range across multiple manipulators increases the importance of robot-specific circuit and power-stage evidence.

Controlled replacement ties the exact label to voltage, rectifier, cooling, motor cables, output map, and RobotWare records.

  • Manipulator record: use the ABB drive table for the exact robot type
  • Product ID: keep 3HAC029818-001 with the MDU-790A identity
  • Controller template: preserve the approved circuit and RobotWare configuration
  • Incoming supply: establish the documented controller voltage arrangement
  • Rectifier path: trace the approved DC-bus source and cabinet connections
  • Protection context: retain grounding, cooling, and protective-device records
  • Power stages: assign each output by the robot-specific ABB table
  • Motor and brake cables: label both ends before removal
  • Motion proof: commission every restored axis through the approved safety process
  • Medium and large IRC5 robots: provide the documented MDU-790A main-drive function
  • Drive-cabinet restoration: recover a verified multi-axis power-stage assembly
  • Planned spare strategy: support exact robot, voltage, and Product ID matching for outages
Description
ABB supplies DSQC 663 as the MDU-790A main drive unit, Product ID 3HAC029818-001, for documented medium and large IRC5 robot configurations. Its drive positions distribute power to the manipulator axes defined by the robot-specific circuit architecture.

The installed robot family and voltage class determine how DSQC 663 is populated and mapped. ABB lists the unit across several robot groups, but the power-stage assignment, connected motors, and rectifier context remain specific to each controller configuration.

For a planned DSQC 663 exchange, preserve the Product ID, robot serial data, supply class, axis-to-output map, motor and brake cables, cooling, DC-bus arrangement, RobotWare template, and fault history. Similar MDU hardware cannot establish compatibility without that evidence.

Technical notes
Voltage class and robot mapping must be established before DSQC 663 is exchanged. ABB uses the MDU-790A across documented medium and large robot families, but power-stage positions, motor and brake cables, rectifier and DC-bus arrangements, and RobotWare templates vary; preserve the complete axis map and prove each motion path after installation.

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.
Can DSQC 663 replace DSQC 406 solely because both are IRC5 main drive units?
No. ABB assigns the MDU-430A to documented small robots and the MDU-790A to medium and large robots; the shared main-drive role does not establish interchangeability.
Why can an axis behave incorrectly after a physically matched DSQC 663 replacement?
The robot-family template may assign the MDU-790A power stages differently. Stop commissioning and compare the manipulator type, circuit diagram, and output table before changing hardware again.
How does voltage class affect DSQC 663 selection?
The supply, rectifier, DC bus, protective hardware, cables, and drive template must belong to the documented controller voltage arrangement before installation.
What should be recorded from the motor connections on DSQC 663?
Label every motor and brake cable at both ends, photograph connector positions, and retain the official robot-specific axis-to-output map before removal.
How does an IRB 8700 change additional-axis planning around DSQC 663?
ABB states that the robot already uses two additional drive units with the main drive unit. Only one further ADU is therefore available for an additional axis.
What excitation-group limit applies when extra axes are planned around DSQC 663?
ABB limits the main drive unit to three axes on EXC1 and three on EXC2. Measurement nodes 1–3 use EXC1, while nodes 4–7 use EXC2.
