Product Introduction
The ABB 3HAC028357-001 is the primary handheld FlexPendant built for all ABB IRC5 robot controller variants. Operators use it to write motion programs and manually jog manipulators during setup.Well, technically it shares communication protocol with older DSQC676 units, yet the ABB 3HAC028357-001 upgrades to a larger LCD and faster touch response with 25 ms input refresh timing. Its internal safety circuit meets ISO 10218 robot personnel protection standards.

Quality Control Process
- Incoming Verification: Cross-reference pendant serial numbers to ABB robot spare part batch logs to reject counterfeit assemblies. Visual inspection checks for cracked touch glass, frayed cable sheathing, or damaged deadman trigger housing (—minor surface plastic scuffs pass QA).
- Live Functional Test: Connect the pendant to a calibrated test cabinet, power the controller, and run startup self-diagnostics. Establish FlexPendant bus handshake with RobotWare, then execute 24-hour cyclic jog and program edit testing with touch input logging.
- Electrical Parameter Test: Use a Megger MIT300 at 500 V to test isolation between signal lines and pendant housing. Validate emergency stop and deadman continuity circuits with a Fluke 115 multimeter across all three switch positions.
- Firmware Verification: Read embedded pendant firmware revision via RobotStudio, log the version to unit trace paperwork, and photograph internal DIP communication jumpers stored inside the rear service compartment.
- Final QC & Packaging: Disconnect and coil the cable neatly, fit factory protective screen film, seal the entire unit inside anti-static shielding bag, and attach a dated QC Passed sticker with assigned test technician ID.
Replacement Pitfall Guide
- Firmware Mismatch: cabinets running RobotWare v5.15 or older cannot establish a stable link with newer ABB 3HAC028357-001 firmware v4.1. Upgrade controller runtime or source legacy pendant hardware.
- DIP Switch / Jumper Misconfiguration: Factory jumper defaults set single-controller mode, but MultiMove rack layouts require alternate bus addressing; misconfigured jumpers trigger persistent pendant connection faults.
- Terminal / Cable Incompatibility: FlexPendant cable pinouts differ between ABB 3HAC028357-001 and DSQC676 older pendants. Avoid over-tightening cable strain reliefs to prevent internal wire breakage.
- Power Supply Mismatch: cabinet auxiliary PSU must maintain 24 V DC ±10% output. Low supply voltage causes touchscreen flickering and random deadman safety circuit dropouts mid-jog operation.
- ESD Damage: Static buildup increases significantly at plant humidity below 30%. Rest the pendant on an anti-static mat during cable swaps; unshielded touch panel contact corrupts onboard communication ICs instantly.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
Compatibility Matrix
- 3HAC028357-001 → 3HAC028357-001 : Direct — Full touch, safety circuit, and bus drop-in replacement
- 3HAC028357-001 → DSQC676 : Needs Adaptation — Smaller screen, older bus protocol, controller software downgrade required
- 3HAC028357-001 → DSQC652 : Incompatible — Digital I/O module lacks pendant HMI communication hardware
- 3HAC028357-001 → DSMB-01C : Incompatible — DC drive trigger PCB has no robot control interface logic
Benchmarks
- Touch input response delay: 25 ms (simulated continuous jogging input load)
- FlexPendant bus throughput: 4.5 Mbit/s (proprietary pendant communication)
