ABB COMAUCR17910381 IGMK6 Robot Teach Pendant – IRC5 FlexPendant

ABB COMAUCR17910381 IGMK6 IRC5 FlexPendant – The Operator Interface at the Core of Every ABB Robot Control Loop

The ABB FlexPendant COMAUCR17910381 (hardware variant IGMK6) is the primary human-machine interface for the IRC5 robot controller family. It is not a peripheral accessory — it is the terminal node of the IRC5 control architecture, responsible for program execution commands, axis jogging, I/O monitoring, event log access, and safety acknowledgment. When this unit fails, the robot cell is effectively locked out. No teach, no jog, no program start. The operational consequence is immediate and total.

This page provides verified technical data, hardware logic analysis, and replacement guidance for maintenance engineers and system integrators sourcing a direct replacement for the COMAUCR17910381 IGMK6 unit.

Technical Parameters

Hardware Logical Analysis

The COMAUCR17910381 IGMK6 FlexPendant operates as a networked terminal within the IRC5 control architecture. Its communication with the IRC5 main computer (DSQC 639 or equivalent) is conducted over a dedicated 100 Mbit/s Ethernet link encapsulated within the proprietary ABB FlexPendant cable assembly. This is not a standard Ethernet drop — the link carries both data and 24 VDC power to the pendant, and the IRC5 controller performs continuous heartbeat monitoring on this channel. A cable fault or connector degradation will trigger a system fault (ERR_FLEXPENDANT_COMM) and halt all motion.

Safety Circuit Architecture: The enabling device (3-position switch) and the emergency stop button are wired through independent dual-channel safety relay circuits inside the pendant housing. These circuits are galvanically isolated from the data bus. The IRC5 safety board monitors both channels independently; a single-channel failure is detected as a fault rather than silently passing. This architecture meets IEC 62061 SIL 2 and ISO 13849-1 PLd requirements — the same safety integrity level required for collaborative robot cells and human-accessible work envelopes.

EMC Design: The pendant enclosure uses a conductive inner shield layer bonded to the cable screen, providing continuous EMC shielding from the IRC5 cabinet ground reference through to the pendant electronics. This is particularly relevant in welding cells and press shops where high-frequency interference from inverter drives and spot welders can corrupt serial communication on unshielded HMI cables. The IGMK6 hardware revision introduced improved ferrite suppression on the internal power rail, reducing susceptibility to conducted emissions in the 150 kHz–30 MHz band.

Touchscreen Controller: The resistive touchscreen is driven by a dedicated controller IC separate from the main application processor. This separation ensures that a touchscreen calibration drift or digitizer fault does not affect the safety-critical enabling device or E-stop circuits, which remain hardware-latched regardless of software state.

RobotWare Compatibility: The IGMK6 hardware variant is compatible with RobotWare 5.x and RobotWare 6.x. When replacing a pendant, the IRC5 controller performs a firmware handshake on first connection. If the pendant firmware version is outside the acceptable range for the installed RobotWare version, the controller will display a version mismatch warning. In most cases, the controller will automatically push the correct pendant firmware over the Ethernet link during the boot sequence — no manual firmware flashing is required provided the RobotWare installation is intact.

System Integration Benefits

• Direct IRC5 Plug-and-Play: The COMAUCR17910381 connects to any IRC5 variant (single cabinet, dual cabinet, panel-mounted, compact) via the standard FlexPendant port. No controller-side configuration is required for basic operation — the IRC5 recognizes the pendant within seconds of connection.
• Deterministic Safety Response: Hardware E-stop and enabling device circuits respond within <20 ms regardless of software load on the application processor. Safety function latency is not subject to OS scheduling jitter.
• Full Diagnostic Transparency: The FlexPendant provides direct access to the IRC5 event log, axis position data, I/O state monitoring, and system variable inspection — all without requiring a PC or external software. Fault diagnosis can begin immediately on the shop floor.
• Program Execution Control: Supports RAPID program start, stop, step-forward, step-backward, and pointer-to-main operations. Operators can modify program data (numeric variables, positions) directly on the pendant without entering the full programming environment.
• Multi-Robot Compatibility: A single FlexPendant can be used across multiple IRC5 controllers in a cell by physically reconnecting to each cabinet. The pendant loads the target controller’s configuration automatically.
• Configurable Hot Keys: Up to 14 programmable function keys can be mapped to I/O signals, RAPID routines, or system functions, reducing operator interaction time for repetitive tasks.
• Motion Mode Flexibility: Supports linear, reorient, and axis-by-axis jogging modes. Coordinate system selection (world, base, tool, wrist) is accessible from the jogging panel without navigating menu hierarchies.
• Reduced Commissioning Time: The integrated production screen and quick-set toolbar allow operators to switch between auto and manual mode, adjust speed override, and acknowledge faults from a single interface layer — reducing the number of interactions required to recover from a fault stop.

Quality Assurance & Global Logistics

Genuine ABB Origin: All COMAUCR17910381 units supplied by siemensplc.com are sourced from verified ABB distribution channels or certified MRO partners. Each unit is inspected prior to dispatch: touchscreen calibration is verified, the enabling device switch travel and detent positions are tested, and the E-stop button mechanical action is confirmed. Units showing connector wear, cable jacket damage, or display defects are rejected. A 12-month warranty covers hardware failure under normal operating conditions.

Packaging: The pendant is packed in anti-static foam-lined cartons with the cable coiled and secured to prevent connector stress. For air freight, the package is sealed in moisture-barrier film. Gross weight including packaging is approximately 2.5 kg.

Logistics from Xiamen, China: Orders confirmed before 14:00 CST are processed for same-day dispatch. Standard export documentation (commercial invoice, packing list, certificate of origin) is prepared for all international shipments. Carrier options include:

• DHL Express: 2–4 business days to Europe, North America, Southeast Asia
• FedEx International Priority: 2–3 business days to the Americas and Middle East
• UPS Worldwide Express: Available for destinations with DHL/FedEx service gaps
