3-12 Installation
EMC Considerations
Trio Motion Technology
3) Screened cables should be used for encoder, stepper and registration input
feedback signals and for the demand voltage from the controller to the servo
amplifier if relevant. The demand voltage wiring must be less than 1m long
and preferably as short as possible. The screen should be connected to earth
at both ends. Termination of the screen should be made in a 360 degree con-
nection to a metallised connector shell. If the connection is to a screw termi-
nal e.g. demand voltage or registration input the screen can be terminated
with a short pig-tail to earth.
4) Connection to the serial ports should be made with a Trio supplied cable.
When a Motion Coordinator is not connected to a PC the serial cable must be
removed as it will act as an antenna for electrical noise if it is left untermi-
nated.
The Euro205 should not be handled whilst the power is connected.
As well as following these guidelines, any installation instructions for other
products in the system must be observe
Motion Coordinator MC206
When the Trio products are tested they are wired in a typical system configu-
ration. The wiring practices used in this test system must be followed to
ensure the Trio products are compliant within the completed system.
A summary of the guidelines follows:
1) The MC206 modules should be earthed via its EARTH connection of the CAN
connector.
2) If any IO lines are not to be used they should be left unconnected rather than
being taken to a terminal block, for example, as lengths of unterminated cable
hanging from an IO port can act as an antenna for noise.
