Overview
ABB DSQC1018 3HAC042766-001 Migration-Ready Drive for Legacy IRB 6700 Control Systems
The ABB DSQC1018 (part number 3HAC042766-001) is a migration-ready axis drive module engineered for direct replacement and retrofit integration within ABB IRB 6700 robot installations. As legacy IRB 6700 systems approach end-of-support cycles and OEM spare parts become increasingly scarce, the DSQC1018 provides a verified, drop-in upgrade path that preserves existing program logic, wiring infrastructure, and cabinet layout — minimizing downtime and protecting capital investment in existing automation lines.
This drive module is confirmed compatible as a direct replacement for the discontinued 3HAC055440-003, 3HAC055440-004, and 3HAC043456-003 drive variants. Engineers planning a retrofit or emergency spare replacement can proceed with confidence: the DSQC1018 maintains the same backplane connector pinout, axis address configuration, and IRC5 controller communication protocol as the original units it replaces.

Retrofit Planning for Existing Automation Systems
Successful integration of the DSQC1018 into a running IRB 6700 cell requires systematic pre-replacement planning. Before removing the failed or aging drive, engineers should document the current axis address assignment — typically configured via DIP switches on the drive faceplate or through the IRC5 FlexPendant axis configuration menu. Mismatched axis addressing is the most common cause of post-swap communication faults and can be avoided entirely with a pre-removal photograph of the switch bank.
Power capacity verification is equally critical. The IRC5 cabinet power supply — most commonly the DSQC661 or DSQC662 PSU module — must be confirmed capable of supporting the DSQC1018’s rated load alongside any co-installed drive modules. In multi-axis cabinets driving IRB 6700 configurations with external axes, total drive bus current draw should be calculated before installation. If the existing PSU is operating near capacity, a parallel PSU expansion or replacement should be planned concurrently.
Terminal wiring on the motor power and resolver/encoder feedback connectors should be inspected and re-torqued during the swap window. Connector housings on legacy IRB 6700 installations often show fretting corrosion at the motor feedback interface — particularly on the DSQC1018’s resolver input connector — which can cause intermittent axis faults post-installation if not addressed. Replacement connector kits are available as separate line items and should be staged alongside the drive module for any installation older than five years.
For cells running RobotWare 5.x, a firmware compatibility review is mandatory. The DSQC1018 3HAC042766-001 is fully validated under RobotWare 6.x and 7.x. Sites still operating on RobotWare 5.x should plan a coordinated RobotWare upgrade alongside the drive replacement — the IRC5 system controller DSQC1000 or DSQC1024 main computer module will require a software key update, and the existing RAPID program backup should be archived before any firmware change is initiated.
HMI screen layouts tied to axis-specific alarm codes may require minor revision following the upgrade, particularly if the replacement drive reports fault codes under a revised diagnostic schema. Operators should be briefed on any changed alarm display behavior before the cell is returned to production. Communication links to upstream SCADA or MES systems via the IRC5 Ethernet/IP or PROFINET interface board (DSQC688 or DSQC1006) should be verified post-swap using a loopback ping and I/O force test before releasing the cell to automatic mode.
Downtime Control During System Migration
Minimizing unplanned downtime during an IRB 6700 drive replacement begins with pre-staging all replacement components before the maintenance window opens. The DSQC1018 should be bench-verified against the axis configuration documentation, and a full RAPID program backup — including module files, system parameters, and I/O configuration — should be saved to a USB key and a network share before power is removed from the IRC5 cabinet.
During the swap, the IRC5 cabinet should be de-energized following the full lockout/tagout procedure, with the drive bus capacitors allowed to discharge fully before the backplane connector is unseated. Re-installation follows the reverse sequence: backplane seating, axis address verification, motor power reconnection, and resolver feedback connector engagement. On power-up, the IRC5 controller should be allowed to complete its full boot sequence before the FlexPendant is used to jog the axis — this ensures the drive firmware handshake completes correctly and axis calibration data is loaded from the system parameters file.
For production environments where even a single-shift outage is unacceptable, a pre-configured hot-spare DSQC1018 — axis-addressed and firmware-matched to the target installation — can reduce the physical swap time to under 30 minutes. KNMKS maintains in-stock inventory of the DSQC1018 3HAC042766-001 with same-day dispatch capability for emergency orders, supporting the fastest possible return-to-production timeline. All units are shipped with a full functional test report and support terms confirmed by quotation documentation.
Retrofit Support FAQ
Q: Is the DSQC1018 3HAC042766-001 a direct replacement for the 3HAC055440-003 without any wiring changes?
A: Yes. The DSQC1018 3HAC042766-001 uses the same backplane connector, motor power interface, and resolver feedback pinout as the 3HAC055440-003 and 3HAC055440-004. No wiring modifications are required for a standard IRB 6700 installation. Axis address DIP switch settings from the removed unit should be replicated on the replacement before installation.
Q: What pre-shipment testing is performed on each DSQC1018 unit?
A: Every DSQC1018 supplied by KNMKS undergoes a full functional test on an IRC5-compatible drive test bench, including power-on self-test, axis communication handshake verification, and load simulation. A test report is included with each shipment. Units are covered by a support terms confirmed by quotation from the date of shipment.
Q: Can the DSQC1018 be used in an IRC5 cabinet running RobotWare 5.x?
A: The DSQC1018 3HAC042766-001 is validated for RobotWare 6.x and 7.x. Use with RobotWare 5.x requires a firmware compatibility review. KNMKS recommends planning a coordinated RobotWare upgrade alongside the drive replacement. Contact our technical team at [email protected] for site-specific compatibility guidance before ordering.
Q: What is the typical lead time and stock availability for the DSQC1018?
A: KNMKS maintains ready stock of the DSQC1018 3HAC042766-001 for immediate dispatch. Standard orders ship within 1–2 business days. Emergency same-day dispatch is available for critical production outages. All units are supplied with a support terms confirmed by quotation and full test documentation.
