8) Ground terminals ( )
• To prevent electrical shock, be sure to ground the robot driver and the robot
body.
• Connect the ground terminals to a proper grounding point (Class D: 100 ohms or
less).
• The ground wire should be thicker than those generally used and as short as
possible.
Note 1: To connect wiring to the terminal block, use crimp terminals that match
the terminal width. If the crimp terminal width is too wide, then a bad
connection or misconnection may result.
Note 2: Separate the robot driver signal input cable and position sensor cable at
least 30cm from the main circuit power cable and control power cable. If
those cables must intersect each other, then route them so that they
intersect at right angles as shown below. The robot driver may result in
malfunction if the cables are not separated from each other.
Main circuit power cable
(L1, L2, L3, U, V, W, (+), (+)1, RB)
Control power supply cable
(L1C, L2C)
Cables should intersect at right angles.
