Internal User I/O Wiring Harness and Air Line
Internal user I/O wiring harness (14 wires: 0.2 mm

2 wires and 1.25 mm x 4 wires), and two air lines are incorporated in the
manipulator for the drive of peripheral devices mounted on the upper arm
as shown in Fig. 7-2 "Connectors for Internal User I/O Wiring Harness and
Air Line".
The connector pins 1 to 16 are assigned as shown in Fig. 7-3 "Details of
the Connector Pin Numbers" on the following page. Wiring must be
performed by users.
3 A or less for each wire
(The total current value for pins 1 to 16 must be 40 A or less.)
2
(The air line inside diameter: 8.0 mm and 6.5 mm.)
Rated current of 350A or less and the rated operational ratio should be
60% or lower.
The allowable operational ratio when it is operated with less current
than the allowable current is calculated by the following formula.
Allowable operational ratio = 60% x (350A/operating current )
