4.4 Shield clamp fitting

Generally, the earth of the shielded cable may only be connected to the connector's SD terminal. However, the
effect can be increased by directly connecting the cable to an earth plate as shown below.
Install the earth plate near the servo amplifier for the encoder cable. Peel part of the cable insulator tot expose
the external conductor, and press that part against the earth plate with the cable clamp. If the cable is thin,
clamp several cables in bunch.
The clamp comes as a set with the earth plate.

4.5 Line noise filter

The line noise filter is effective in suppressing noises radiated from the cables connected to the main circuit
power in the servo amplifier (converter unit) and those connected to the servo amplifier power output, and also
in suppressing high-frequency leakage current (zero-phase current) especially within 0.5MHz to 5MHz band.

4.5.1 Connection example

The line noise filters are used for the cables connected to (L
those connected to (U, V, and W) the servo amplifier power output. Pass each of 3-phase cables through line
noise filters an equal number of times in the same direction.
