Performance

Maximum payload What is this?	5 kg [1]
Reach What is this?	994 mm [1]
Degrees of freedom What is this?	6 axes [1]
Repeatability What is this?	±0.03 mm [1]FANUC America does not name the test standard on its product page; FANUC Europe's datasheet references ISO 9283.
Allowable wrist moment / inertia What is this?	J4 19 Nm / 0.77 kg·m²; J5 15.4 Nm / 0.5 kg·m²; J6 6.7 Nm / 0.1 kg·m² [1]

Motion

Maximum TCP speed What is this?	1,000 mm/s in collaborative mode; 2,000 mm/s in high-speed mode [1]FANUC Europe's datasheet describes these as maximum linear speeds of the tool centre point.
Joint working ranges What is this?	J1 380°, J2 360°, J3 380°, J4 380°, J5 360°, J6 450° [1]FANUC publishes each axis's total travel. Universal Robots and ABB publish ± limits, so ±360° equals 720° of travel.

Power

Average power consumption	0.3 kW [2]

Environment

Ingress protection	IP67 (body, wrist and J3 arm) [1]FANUC Europe's datasheet notes that IP67 does not apply with the food-grade option.
Ambient operating temperature	0–45 °C [2]
Humidity	≤75% RH without dew or frost; ≤95% RH short term (within one month) [2]
Noise	< 70 dB [2]

Physical

Mechanical weight	25 kg [1]
Mounting	Floor, angle or inverted [1]

Controller and communications

Controller	R-30iB Plus [1]

Where it sits in the range

CRX-5iA lists 5 kg at a 994 mm reach and ±0.03 mm repeatability, with a 25 kg mechanical weight. FANUC publishes allowable wrist moments and inertias for each wrist axis, a practical limit when sizing offset tools.

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FANUC's cited pages do not publish per-axis maximum speeds or a force-sensing specification for CRX-5iA, so RoboMag leaves them unknown.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-5iA. Cycle time, reliability and the safe speed of a finished cell depend on the tool, the task and the risk assessment.
