Noise on the Reference Input Line
If the reference input line is affected by noise, ground the 0V line (SG) of the
reference input line. If the main circuit wiring for the motor is accommodated in a
metal conduit, ground the conduit and its junction box.
All grounds must be made to only one point in the system.
Using Noise Filters
Use a noise suppression filter to prevent noise generated by the power supply line.
Install a noise filter on the power supply line for peripheral equipment as necessary.
The following table recommends noise filters for each servo amplifier model.
