Internal User I/O Wiring Harness and Air Line
Internal user I/O wiring harness (14 wires: 0.2 mm
2
x 8 wires, 0.75 mm
2
x
2 wires and 1.25 mm
2
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
The connector pins 1 to 16 are assigned as shown in
on the following page. Wiring must be
performed by users.
The allowable current for internal user
I/O wiring harness
3 A or less for each wire
(The total current value for pins 1 to 16 must be 40 A or less.)
The maximum pressure for the air line 490 kPa (5 kgf/cm
2
) or less
(The air line inside diameter: 8.0 mm and 6.5 mm.)
The allowable current for arc welding
power cable
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 )
