FAQ

How can I identify a failure in the DSQC 639 unit?

System failures typically manifest as a "Computer Failure" status LED on the controller front panel, an inability to boot the RobotWare software, or persistent communication timeouts with the FlexPendant. If the internal cooling fan fails or the CMOS battery is depleted, the DSQC 639 (3HAC025527-004) may also trigger critical system alarms.

Does this unit come pre-loaded with RobotWare software?

New or refurbished DSQC 639 (3HAC025527-004) units are typically supplied as hardware only. The specific RobotWare version and system keys required for your robot model must be installed via a standard system restore or by using the ABB RobotStudio Installation Manager.
