ABB DSQC655 3HAC025562-001 Storage Capacitor Unit

Configured for temporary back-up power execution in IRC5 Robot Controller platforms, the ABB DSQC658 3HAC025562-001 (DSQC655 Storage Capacitor Unit) provides direct physical/electrical execution.

Hardware Specifications

Deterministic Backplane Bus Integration

The DSQC655 ultracapacitor array interfaces directly with the IRC5 controller main DC bus, charging rapidly from the backplane power supply in under one minute. Onboard control circuits manage charge/discharge profiles without inducing voltage fluctuations on internal bus tracks. Maintaining firmware flash compatibility across RobotWare platforms, the unit releases energy during unexpected AC mains interruption, supplying ride-through voltage to preserve robot encoder revolution counts and arm position registers before controller shutdown.

Frequently Asked Questions

Q: How does the DSQC655 board prevent axis position loss during sudden mains failures? A: Upon loss of input AC line voltage, the unit instantly supplies stored 24 VDC energy to the main controller logic, providing power to write active revolution counter data into non-volatile storage.

Q: What maintenance steps ensure long-term functionality of the ultracapacitor module? A: Inspect the unit every 6 months for signs of physical swelling, electrolyte seepage, or terminal corrosion, especially in high-vibration robot mounting environments.

Q: Can the DSQC655 3HAC025562-001 be used in older pre-M2006 IRC5 controller variants? A: No, this specific part number is designed for M2006 onwards and collaborative robots; older control cabinets require alternative legacy storage modules such as 3HAC020150-001.

Field Installation Guidelines

Ensure complete de-energization of the main IRC5 control cabinet before installing or servicing the DSQC655 module. Disconnect external mains feeds and allow residual internal bus voltage to decay fully. Handle the assembly using grounded ESD wrist straps to protect onboard circuitry against electrostatic discharge. Slide the module into its designated cabinet slot, securing mechanical fasteners to resist vibration. Connect the 24 VDC bus wiring harnesses, verifying correct polarity prior to power-up. Route wiring away from high-voltage AC motor drives to minimize electromagnetic noise coupling.
