Cabling the VRKT•L••NC

Procedure Overview

Perform the following procedures to cable the robot:

Cabling the Robot

Step

Action

1

For each of the two main motors (1), feed one hybrid cable from a Distribution Box ILM62DB and connect them to the motors.

NOTE: For equipment that you are supplying that is not described in the present document, consult the documentation for those products.

2

Verify the correct routing and fastening of the cables to help prevent any collision of cables and moving parts.

 DANGER
LOOSE WIRING OR CABLING CAUSES ELECTRIC SHOCK
Tighten wiring or cabling connections in conformance with the torque specifications.
Failure to follow these instructions will result in death or serious injury.

For further information, refer to Lexium 62 Hardware Guide or Lexium 52 Hardware Guide.

Grounding the Robot

NOTE: When grounding the robot, use cables that comply with the applicable local standards, for example, cables that conform to NEC 70 / NFPA 79 in the USA.

Step

Action

1

Fasten the ground cables to the ground connections (1) of the robot motors. The ground connections are marked with the following symbol:

Tightening torque: 2.9 Nm (25.7 lbf-in)

NOTE:
  • The graphic is an example for the position of the ground connection at a main axis motor.

  • The external protective ground connection wiring is determined by a number of variables. See the important safety information at the end of this table.

2

Verify the correct routing and fastening of the cables to help prevent any collision of cables and moving parts.

 DANGER
ELECTRIC SHOCK DUE TO IMPROPER GROUNDING
  • Ground robot components in accordance with local, regional and/or national standards and regulations at a single, central point.
  • Verify that the motors are connected to the central ground.
Failure to follow these instructions will result in death or serious injury.

Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.

Reducing Risks Around the Robot

Step

Action

1

Install external safety-related devices in accordance to local regulations and standards.

2

When designing the safety-related devices, assume that the robot cannot be stopped by internal logic and must be stopped by the external safety-related devices.

NOTE: More information about the circuitry of emergency stop and additional protection elements is contained in the document Lexium 52 Hardware Guide, Lexium 62 Hardware Guide, or Lexium 62 ILM Hardware Guide.
