Grounding Wire
D
In conformance with local electrical codes, ground the SERVOPACK’ s grounding termi-
nal
(grounding resistance: 100
Ω ο
r less).
D
Be sure to connect the grounding wire of the servomotor to
of the SERVOPACK.
D
Never share the grounding cable or grounding rod with welders, power equipment, or other
high-voltage devices. Separate the grounding cable from wiring of high-voltage equip-
ments.
D
Make the grounding wire as short as possible. As for cable size, see

Noise Control
If the signal line is affected by noise, malfunction may result.
D
Separate power cables from control cables.
D
Make the signal line as short as possible and use twisted-pair wires.
Never use a line filter (for power input) for servomotor circuit. If peripheral devices malfunc-
tion due to the noise from SERVOPACK, insert a line filter (for output, type LF-310KA, made
by Tokin Corp.) between servomotor and SERVOPACK.
