Motion
| Maximum TCP speed What is this? | 1,200 mm/s in collaborative mode; 2,500 mm/s in high-speed mode [1]FANUC Europe's datasheet describes these as maximum linear speeds of the tool centre point. |

Where it sits in the range
CRX-3iA is the lightest arm in FANUC's CRX series at 11 kg, with a 3 kg payload and 692 mm reach. FANUC America lists the highest TCP speeds in the series for it: 1,200 mm/s in collaborative mode and 2,500 mm/s in high-speed mode.
It is also the only CRX model whose FANUC America page lists wall mounting alongside floor, ceiling and angle.
What the cited documents do not give
FANUC's cited pages do not publish per-axis maximum speeds or a force-sensing specification for CRX-3iA, so RoboMag leaves them unknown. FANUC Europe gives average rather than maximum power consumption, which is not comparable with the maximum figures Universal Robots publishes.
RoboMag has not physically tested CRX-3iA. Cycle time, reliability and the safe speed of a finished cell depend on the tool, the task and the risk assessment.
