Grounding the Motion Mate DSM314 Motion System
The DSM314 System must be properly grounded. Many problems occur simply because this
practice is not followed. To properly ground your Motion Mate DSM314 system, you should
follow these guidelines:
•
The grounding resistance of the system ground should be 100 ohms or less (class 3
grounding).
•
The DSM314 faceplate shield ground wire (shipped with the module) must be
connected from the ¼ inch blade terminal at the bottom of the module to a panel
frame ground.
•
If an axis terminal board is use
d, two shield (“S”) connections are provided and
one
of these must be connected to a panel frame ground.
•
The system ground cable must have sufficient cross-sectional area to safely carry the
accidental current flow into the system ground when an accident such as a short
circuit occurs. Typically, it must have at minimum the cross-sectional area of the AC
power cable. Figure 22 illustrates the grounding systems.
•
The amplifier ground connections, power earth (PE) connections, and motor frame
ground connections should always be wired to conform to local electrical wiring
regulations. When installing in conformance to CE Mark directives, a grounding bar
and clamp(s) (ordered separately) is required for the terminal block to amplifier
cable.
Refer to Chapter 3, Installing and Wiring the DSM314, I/O Cable Grounding section, for
more details.
