3.4 Noise Measures and Grounding
3.4.1 Grounding
Power terminal E is used for protective grounding. Provide Class D grounding from this terminal.
Provide dedicated grounding from the Tabletop Robot.
Do not ground the robot as shown above.
3.4.2 Noise sources and noise elimination
There are many noise sources, but solenoid valves, magnet switches and relays are of particular
concern when building a system. Noise from these parts can be eliminated using the measures
specified below:
[1] AC solenoid valve, magnet switch, relay
Measure --- Install a surge killer in parallel with the coil.
Surge killer
Point
Wire from each coil over the shortest distance.
Installing a surge killer on the terminal block,
etc., will be less effective because of a longer
distance from the coil.
Single-phase 200 to 230 VAC
Class D grounding
(protective grounding)
Grounding for noise elimination
Connect the grounding terminal
with the metal enclosure using a
cable of the largest possible size
over the minimum distance.
