ABB 1910061947 D1724-20B Migration-Ready Air Bearing Motor

Overview

ABB 1910061947 D1724-20B Migration-Ready Air Bearing Motor: Legacy System Retrofit and Compatibility Upgrade

The ABB 1910061947 D1724-20B (also cross-referenced as B1724-20B, 3N3745W, 2C0683, and 3HS2000-01) is a migration-ready air bearing motor engineered for direct replacement in ABB IRB-series robot installations and legacy motion control platforms where the original OEM unit has reached end-of-life or is no longer available through standard supply channels. As ABB progressively phases out support for older IRB controller generations, facilities running continuous production lines face increasing pressure to source verified drop-in replacements that preserve existing wiring harnesses, encoder feedback loops, and drive parameter sets without requiring full system redesign.

This unit is fully tested prior to shipment and ships with a support terms confirmed by quotation covering manufacturing defects and functional performance under rated operating conditions. In-stock inventory is maintained across regional distribution hubs to support urgent retrofit timelines and minimize unplanned downtime exposure.

Retrofit Planning for Existing Automation Systems

Successful integration of the ABB 1910061947 D1724-20B into a legacy production environment requires a structured pre-retrofit assessment. Before removing the failed or degraded unit, maintenance engineers should back up all axis parameters stored in the ABB IRC5 or S4C drive module, including motor type codes, inertia values, and current limit settings. These parameters are typically stored in the robot controller’s system configuration files and must be restored after the new motor is seated and mechanically secured.

In installations where the ABB DSQC 508 or DSQC 532 I/O modules are present in the same control cabinet, it is important to confirm that the cabinet power budget accommodates the motor’s rated draw without tripping the 24VDC supply rail shared with digital I/O cards. Similarly, if the system includes an ABB DSQC 604 power supply unit, verify that the auxiliary output capacity remains within specification after the motor replacement is energized. Facilities that have previously upgraded their control cabinets to include the ABB Panel PC 800 for HMI functions should also confirm that any axis-specific HMI screens referencing motor status tags are updated to reflect the new unit’s feedback signal range.

For systems that include an ABB Fieldbus Adapter DSQC 352 or equivalent DeviceNet/PROFIBUS communication module, no protocol reconfiguration is required when replacing the motor on a like-for-like basis, as the communication path runs through the drive and controller rather than the motor itself. However, if the retrofit is being performed as part of a broader migration from an S4-generation controller to an IRC5 platform, the motor’s resolver wiring may need to be adapted to the new drive’s feedback connector standard — a task that should be planned with the site’s commissioning engineer and documented in the retrofit work order.

Where the installation includes ABB SMB (Serial Measurement Board) units for axis position tracking, confirm that the SMB battery is replaced concurrently with the motor swap to avoid axis calibration loss during the first power cycle after reinstallation. This is a commonly overlooked step that can add several hours to the recommissioning process if not addressed proactively.

Downtime Control During System Migration

Minimizing production downtime during an air bearing motor replacement on an ABB IRB-series robot requires advance preparation across three areas: spare parts staging, program logic preservation, and post-swap verification sequencing.

Before the maintenance window opens, the replacement ABB 1910061947 D1724-20B unit should be on-site and pre-inspected. All axis parameter files should be exported from the controller and stored on an external USB or network backup location. If the robot is integrated into a production cell with safety PLC interlocks or light curtain logic, the safety system should be placed in bypass mode under a formal permit-to-work procedure to prevent nuisance trips during the swap.

During the physical replacement, the motor connector should be unplugged before any mechanical fasteners are loosened to avoid stress on the wiring harness. After the new unit is installed and connectors are re-seated, perform a cold start of the controller before enabling servo power. This allows the drive to re-initialize motor feedback without carrying over any fault state from the previous unit.

Post-installation, the axis mastering procedure must be completed before returning the robot to automatic mode. For IRB-series robots, this typically involves a fine calibration routine using the robot’s calibration pendulum or reference marks on the mechanical stops. Once mastering is confirmed, run the robot through its full programmed path at reduced speed (typically 10–25%) before restoring full production speed. This step protects both the tooling and the surrounding cell infrastructure from any residual parameter offset that may not have been captured during the backup phase.

With proper preparation, a like-for-like motor swap on an ABB IRB robot can typically be completed within a 4–8 hour planned maintenance window, including parameter restoration and path verification. In-stock availability of the ABB 1910061947 D1724-20B from our warehouse ensures that the unit can be dispatched for next-business-day delivery in most regions, supporting tight maintenance scheduling without extended lead time exposure.

Retrofit Support FAQ

Q1: Is the ABB 1910061947 D1724-20B a direct replacement for the B1724-20B and 3HS2000-01?
Yes. The 1910061947 D1724-20B is cross-referenced against B1724-20B, 3N3745W, 2C0683, and 3HS2000-01. These part numbers refer to the same motor assembly used across multiple ABB IRB robot variants. Before ordering, confirm the motor’s mounting orientation and connector type against your robot’s maintenance manual to ensure the cross-reference applies to your specific axis and robot model revision.

Q2: What commissioning steps are required after installation?
After mechanical installation and connector re-seating, perform a controller cold start, restore axis parameters from your pre-swap backup, and complete the axis mastering (fine calibration) procedure. Run the robot at reduced speed through its full programmed path before returning to automatic production mode. If the SMB battery was not replaced concurrently, axis position data may be lost on the first power cycle — plan for this contingency in your maintenance schedule.

Q3: Has this unit been tested before shipment, and what does the support terms cover?
Yes. Every ABB 1910061947 D1724-20B unit is functionally tested prior to dispatch. The support terms confirmed by quotation cover manufacturing defects and confirmed performance failures under rated operating conditions. Support requests require the unit to be returned in its original packaging with a fault description. Units showing evidence of incorrect installation, overvoltage, or mechanical impact damage are not covered under the standard support terms terms.

Q4: What is the typical lead time, and do you maintain stock?
We maintain in-stock inventory of the ABB 1910061947 D1724-20B to support urgent retrofit and breakdown replacement scenarios. Standard orders are dispatched within 1–2 business days. For large-quantity orders or scheduled maintenance programs requiring multiple units, contact our sales team to confirm availability and arrange priority allocation from our regional stock buffer.
