3 DESIGN
3.2.1 Power supply circuit design
This section describes the protective coordination and noise suppression techniques of
the power supply circuit.
(1) Separation and protective coordination (leakage current protection,
over current protection) of power supply systems
When wiring, separate the lines of Multiple CPU system power supplies from
those of the I/O equipment and servo amplifier as shown below.
When there is much noise, connect an insulation transformer.

(2) Grounding
The Motion system may malfunction as it is affected by various noises such as
electric path noises from the power supply systems, radiated and induced noises
from other equipment, servo amplifiers and their cables, and electromagnetic
noises from conductors. To avoid such troubles, connect the earthing ground of
each equipment and the shield grounds of the shielded cables to the earth.
Also use ferrite cores (ex., ZCAT3035-1330(TDK make)) to prevent the sneak
noises from the SSCNET.
For grounding, use the exclusive ground terminal wire of each equipment or a
single-point earth method to avoid grounding by common wiring, where
possible, since noises may sneak from other equipment due to common
impedances.
