## Safety

- Operating ambient temperature limit is 0–45 °C; humidity limit is 20–85% RH without condensation; vibration limit is 0.5 G (4.9 m/s²).
- Permitted installation height is not higher than 1,000 m above sea level; at higher locations the permitted temperature is affected by height.
- J6 cable routing limit: use ±210° when cables pass through the J6 hollow hole; ±360° only when cables are not routed through the hollow hole and conditions permit.
- Floor installation only.

## Study notes

- Structure is articulated with 6 axes and an AC servo drive system.
- Wrist payload is 400 kg; forearm payload is maximum 50 kg.
- Allowable static load torque at wrist: J4 3450 N·m, J5 3450 N·m, J6 1725 N·m.
- Allowable moment of inertia at wrist: J4 600 kg·m², J5 600 kg·m², J6 400 kg·m².
- Position repeatability conforms to JIS B 8432.
- J6 maximum envelope is ±360°; factory software limit is ±210°. Use ±210° when cables pass through the J6 hollow hole; ±360° only if cables are not routed through the hollow hole and conditions permit.
- Ambient humidity is 20–85% RH without condensation; vibration is not more than 0.5 G (4.9 m/s²).
- Permitted height is not higher than 1,000 m above sea level; at higher locations the permitted temperature is affected by height.
- Applications listed: machine tending, material handling, palletizing, and spot welding.
