ABB 3HAC026787-002 Replacement Cable for IRC5

Product Overview

ABB 3HAC026787-002 Replacement Cable for IRC5: Smooth Migration & Backward-Compatible Upgrade

The ABB 3HAC026787-002 is a 15-meter power control cable engineered specifically for the ABB IRC5 robot controller family. As the IRC5 platform continues to serve as the operational backbone of industrial automation cells worldwide, the need for specification-matched, OEM-compatible replacement cables has grown substantially — particularly as original cables reach end-of-service life, sustain jacket damage during maintenance cycles, or are lost during facility relocations. TOPNLMS supplies the 3HAC026787-002 as a direct drop-in replacement, enabling maintenance engineers and system integrators to restore full robot functionality with zero controller reconfiguration and minimal unplanned downtime.

This cable connects the IRC5 controller cabinet to the robot manipulator, carrying both power and control signals across a shielded, flexible 15-meter run. Its connector pinout, shielding specification, and cable jacket rating are fully compatible with the IRC5 Single Cabinet Controller, IRC5 Compact Controller, and IRC5 Panel Mounted Controller variants. Whether you are replacing a worn cable on an IRB 1600, IRB 2600, IRB 4600, or IRB 6640 manipulator, this cable installs without any wiring modification to the existing cable management tray or drag chain assembly. No re-pinning, no adapter harnesses, and no signal routing changes are required.

For facilities managing a mixed fleet of ABB robots, the 3HAC026787-002 is interchangeable across IRC5 controllers running RobotWare 5.x and RobotWare 6.x firmware. No RAPID program changes, no I/O remapping, and no SMB (Serial Measurement Board) recalibration are required following a cable swap — the replacement is purely mechanical and electrical, making it equally suitable for planned preventive maintenance and emergency breakdown recovery. This compatibility profile significantly reduces the risk of extended downtime during a cable failure event, as no software specialist is required on-site to complete the restoration.

For facilities currently migrating from the older ABB S4C+ controller platform to the IRC5 architecture, the 3HAC026787-002 is the correct power control cable to install on the new IRC5 cabinet. The S4C+ platform uses a different cable standard (3HAC7998-1 series), and the 3HAC026787-002 is IRC5-specific — making it a key line item on any S4C+ to IRC5 migration bill-of-materials. Its 15-meter length accommodates the majority of floor-mounted IRC5 installations where the controller cabinet is positioned at the perimeter of the robot work envelope.

Seamless Upgrade Solutions

A cable replacement rarely occurs in isolation. During an IRC5 maintenance window, engineers frequently address adjacent components to prevent repeat failures and extend the overall service interval. When replacing the 3HAC026787-002, it is standard practice to simultaneously inspect or replace the SMB battery pack (3HAC044075-001) that powers the serial measurement board — a low-cost consumable that, if neglected, can trigger axis calibration errors immediately after a cable swap. The teach pendant cable (3HAC031683-001) and the FlexPendant unit itself should also be checked for jacket cracking or connector wear, as both share the same cable management tray and are subject to identical mechanical stress cycles.

For IRC5 controllers operating in high-cycle environments, the DSQC 661 main computer board and the DSQC 662 axis computer are worth inspecting during the same downtime window. If the facility is migrating from an S4C+ controller to the IRC5 platform, the upgrade will require a new DSQC 1000 drive unit alongside updated I/O modules such as the DSQC 652 digital I/O board, which provides 16 digital inputs and 16 digital outputs compatible with the IRC5 I/O bus architecture. The 3HAC026787-002 cable is fully compatible with this upgraded I/O configuration without any signal routing changes.

In applications where the IRC5 controller communicates with a PROFIBUS DP network, the DSQC 667 PROFIBUS adapter board should be verified for firmware compatibility with the installed RobotWare version. For EtherNet/IP-based cells, the DSQC 688 EtherNet/IP adapter provides the network interface layer, and its configuration remains unaffected by a power control cable replacement. Facilities running ABB’s SafeMove safety module (DSQC 647) should confirm that the safety configuration backup is current before performing any cable work, as a precautionary measure against accidental parameter loss during controller power cycling.

Retrofit Guidance FAQ

Q: Does replacing the 3HAC026787-002 require RAPID program changes?
A: No. This is a hardware-layer cable replacement. RAPID programs, tool data, work object definitions, and I/O signal assignments are stored in the IRC5 controller’s flash memory and are unaffected by a cable swap.

Q: Is the 15 m length compatible with my existing cable tray?
A: The 15 m variant is the standard length for most IRC5 installations with a floor-mounted controller cabinet positioned at the edge of the robot work envelope. If your controller is ceiling-mounted or located more than 12 m from the manipulator base, please contact us to confirm routing feasibility before ordering.

Q: Will this cable work with IRC5 controllers running RobotWare 5.15?
A: Yes. The 3HAC026787-002 is a passive cable assembly with no firmware dependency. It is compatible with all RobotWare 5.x and 6.x versions.

Q: Can I use this cable during an S4C+ to IRC5 migration?
A: The S4C+ platform uses a different cable standard (3HAC7998-1 series). The 3HAC026787-002 is IRC5-specific and is not backward-compatible with S4C+ controllers. It is the correct cable to install on the new IRC5 controller as part of the migration.

Q: What is the installation procedure?
A: Power down the IRC5 controller via the main switch and follow ABB’s lockout/tagout procedure. Disconnect the existing cable at both the controller cabinet and the manipulator base. Route the new 3HAC026787-002 through the existing cable management tray, connect both ends, and restore power. No SMB recalibration is required unless the manipulator axes were moved during the cable replacement.

Q: Is this cable compatible with PROFIBUS and EtherNet/IP communication protocols?
A: Yes. The 3HAC026787-002 operates at the physical power and signal layer of the IRC5 system. It is protocol-agnostic at the cable level and fully compatible with IRC5 controllers configured for DeviceNet, PROFIBUS DP, or EtherNet/IP fieldbus communication.
