2) Use Class D grounding (grounding resistance
100Ω or less).
Dedicated grounding separated from the other
devices should be used.

the grounding wire. The grounding point should be
(Normal)
as close to the robot arm and controller as possi -
ble, and the length of the grounding wire should
be short.
