Chapter 3 Operation Order and Installation
2) Connection of power and earth wires
Earthing and power supply wires for the motion controller system must be connected as described below.
(a) Earth the control panel with a thick wire so that a low impedance connection to ground can be ensured even at
high frequencies.
(b) The function of LG (Line Ground) and FG (Frame Ground) terminals is to pass the noise generated in the motion
controller system to the ground, so impedance that is as low as possible must be ensured.
(c) The earthing wire itself can generate the noise, so wire as short and thick to prevent from acting as an antenna.
(d) Attach ferrite core under the power cable to satisfy CE specification.
