ABB IRB660 Series Technical Notes

The Evolution of IRB660 Architecture

The IRB660 platform was introduced as a successor to the IRB640 and IRB6600 palletizing variants, consolidating ABB's high-payload robot lineup under a unified mechanical architecture. Early production units (pre-2010) utilized the S4C+ controller ecosystem with discrete servo drive modules. The transition to the IRC5 controller (introduced circa 2005–2007) brought integrated drive technology, modular axis computer boards, and the DSQC (Drive System Quad Controller) module family. The current generation operates under IRC5 with Panel Mounted Controller (PMC) or Cabinet Controller variants.

Key architectural milestones: the shift from analog resolver feedback to digital encoder systems improved positioning repeatability to ±0.05 mm. The introduction of SafeMove2 safety software (post-2015 firmware) added certified speed and position monitoring without external safety PLCs. Compatibility between IRC5 generations is limited — DSQC modules from S4C+ controllers are not interchangeable with IRC5 drive units. Engineers maintaining mixed-generation fleets must verify controller revision before ordering replacement modules.

Sourcing Hard-to-Find & Obsolete IRB660 Parts

Several IRB660-compatible modules — particularly DSQC-series boards from pre-2015 IRC5 revisions — have reached end-of-production status with ABB. DriveKNMS maintains a dedicated inventory of tested surplus and refurbished units for the IRB660 platform, including discontinued axis computer boards, legacy FlexPendant units, and first-generation SafeMove modules.

Quality Control for the IRB660 Range

All IRB660 servo motors and drive modules processed by DriveKNMS undergo a structured verification protocol prior to dispatch. Servo motor units (including 3HAC057432-001) are tested for winding insulation resistance (Megger test, minimum 100 MΩ at 500 VDC), encoder signal integrity, and no-load current draw within OEM specification bands. IRC5 drive modules are bench-tested under simulated load conditions using ABB-compatible test rigs, verifying DC bus regulation, PWM output waveform symmetry, and fault code response.
