2.2.4 Grounding procedures
(1) Grounding methods
1) There are three grounding methods as shown in
, but the dedicated grounding (
Fig. 2-8 (a)
) should be
used for the robot arm and controller when possible. (Refer to the separate " Controller Setup, Basic
Operation and Maintenance" for details on the controller grounding.)
2) Use Class D grounding (grounding resistance 100Ω or less). Dedicated grounding separated from the other
devices should be used.
3) Use a AWG#11(4.2mm
2
) or more stranded wire for the grounding wire. The grounding point should be as
close to the robot arm and controller as possible, and the length of the grounding wire should be short.
Fig.2-8 ： Grounding methods
(2) Grounding procedures
1) Prepare the grounding cable (AWG#11(4.2mm
2
) or more) and robot side installation screw and washer.
2) If there is rust or paint on the grounding screw section (A), remove it with a file, etc.
3) Connect the grounding cable to the grounding screw section.
