(1) Grounding methods

Fig.2-4 ： Grounding methods

1)There are three grounding methods as shown in Fig. 2-4, but the dedicated grounding (Fig. 2-4(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(3.5mm2) or more stranded wire for the grounding wire. The grounding point should be as close to the robot arm and controller as possi- ble, and the length of the grounding wire should be short.
