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 lines
Separate the lines for Motion controller's power supplies from the lines for I/O
devices and servo amplifiers as shown below.
When there is much noise, connect an insulation transformer.
The Motion controller may malfunction as it is affected by various noises such as
electric path noises from the power supply systems, and electromagnetic noises
from conductors. To avoid such troubles, set the 24VDC power supply according
to application.
