ABB DSQC561 push-button brake

1. Product Overview

• Model / Identifier: DSQC561

• Associated Part Number: e.g. 3HAC16036-1/03 is a variant tied to DSQC561 in ABB robot spare parts listings.

• Purpose: A push-button manual brake release unit used on ABB robots (e.g. IRB series). Through mechanical operation, it allows manual release of the motor brake, enabling free movement of axes or safe maintenance operations.

• Robot Series: It is used in ABB robot families such as S4 / S4C / S4C+ for brake release applications.

• Replacement / Succession: Some ABB robot manuals indicate that DSQC561 may have been succeeded by DSQC1052 as the brake release module in newer revisions.

2. Key Functions / Features

1. Manual Brake Release
   By pressing the button, the unit manually disengages the motor brake, allowing the axis to move even when the system is powered off or in maintenance mode.

2. Mechanical + Electrical Integration
   The unit includes mechanical button mechanism, mounting structure, wiring harness, and possibly signal feedback components.

3. Versatile Compatibility
   Designed to work with multiple module versions (for example part number variants like 3HAC16036-1/03) under the DSQC561 classification.

4. Maintenance & Safety Operation
   Useful during system shutdown, maintenance, or emergency states to allow safe manual movement of robot axes.

5. Compact / Simple Structure
   Compared to full brake assemblies, this push-button unit is relatively lightweight and easier to install or replace.

6. Integration with Robot Control System
   In robot modes such as manual, calibration, or maintenance, this unit interfaces mechanically (and possibly electrically) with the controller’s brake release logic.

3. Typical Applications

• On ABB robots (IRB and similar) as the manual brake release interface

• Use in robot systems to provide a safe manual override for brake disengagement

• During tuning, calibration or service interventions where axes need to be moved manually

• In maintenance, inspection or emergency scenarios to release brakes when the system is offline

• With robot controllers and safety modules to ensure controlled brake release under defined conditions

4. Installation / Usage / Selection Considerations

1. Model and Compatibility Check

   • Verify that the push-button unit matches the robot and brake version (DSQC561 vs later DSQC1052).

   • Cross-check part numbers from ABB’s parts lists or maintenance documentation.

2. Mechanical Installation Precision

   • The position, travel stroke, and force of the button must align with the brake mechanism.

   • Use proper mounting hardware and sturdy support to withstand vibration and repeated use.

3. Electrical / Feedback Wiring

   • If the unit includes electrical feedback or signaling, ensure pinouts and wiring match control system requirements.

   • Maintain proper insulation, shielding, and connector quality.

4. Durability and Lifetime

   • The mechanical button is subject to wear and tear; design with expected service life in mind.

   • Avoid excessive mechanical stress, repeated forced operations, or operation under vibrations beyond spec.

5. Maintenance and Cleaning

   • Periodically inspect the button mechanism, return springs, mounting points, and wiring for wear, corrosion, or binding.

   • Keep the unit clean; prevent dust, particles or contamination that may impede smooth action.

6. Safety and Locking

   • In automatic / operational modes, the button should not allow unintended brake release—incorporate locking or interlock measures.

   • Ensure the robot’s safety and control systems manage and validate any manual release appropriately.

7. Documentation & Spare Matching

   • Maintain spare units as part of robot maintenance inventory.

   • Refer to ABB official spare parts catalogs and repair manuals for precise mechanical drawings, wiring, installation instructions, and specifications.
