Noise Reduction
This section provides a wiring example with a G5-series Linear Motor as a means to prevent anticipated
noise interference with peripheral equipment when a linear system is installed.
*1
Not required for single-phase models with a 100-VAC input.
Note
For models with a single-phase power supply input, the main circuit power supply input terminals are L1 and
L3.
•
Use a ground plate for the frame ground for each unit, as shown in the above diagrams, and ground
to a single point.
•
Use ground lines with a minimum thickness of 3.5 mm
2
, and arrange the wiring so that the ground
lines are as short as possible.
•
A no-fuse breaker, surge absorber, and noise filter should be positioned near the input terminal block
(ground plate), and I/O lines should be separated and wired at the shortest distance.
