2.7. USER CIRCUIT
See figure 2.9.: Arm - Rear cable outlet
See figure 2.10.: Arm - Vertical cable outlet
The arm cabling system is made up of a harness containing several electrical cables used to power the
servomotors (power, brakes, coders), the distributors, and the login user socket. These components are
connected by means of removable connectors.
It also integrates the pneumatic pipes that provide 2 pressure supplies (A1) and (P2) near the tool clamp.
As an option, the arm incorporates the pneumatic pipes supplying the (EV1) electric distributor and those
used for the (EV1) electric distributor outlets on the forearm at (A1) and (B1). The robot also has a pressure
source (P2) close to the tool clamp.
The wiring is inside the structure and routed through the centre of the joints. It is connected to the arm base
on a plate which includes several electrical and pneumatic components such as:
Arm - Rear cable outlet (figure 2.9)
• Arm ground connection (1).
• Arm/controller connector (J1201).
• connector intended for the user for possible electrical connection of grip (J1202).
• Brake release selector (2).
• Brake release pushbutton (3).
• Pneumatic connections to the (P1) and (P2) compressed air networks.
• Connection for creating overpressure in the (P3) arm.
Arm - Vertical cable outlet (figure 2.10)
• Arm/(J1201) controller interconnection socket.
• connector intended for the user for possible electrical connection of grip (J1202).
• Socket for connection of the remote brake release box (J1204).
• Pneumatic connections to the (P1) and (P2) compressed air networks.
• Connection for creating overpressure in the (P3) arm.
• Remote brake release box (4).
•
Brake release selector (2).
• Brake release pushbutton (3).
• Pneumatic exhaust muffler .
CAUTION:
The overpressure must never exceed 20 mbar (0.28 psi).
CAUTION:
Do not add wires or cables to arm wiring as this may cause premature wear of the arm
electrical wiring and lead to loss of the warranty.
