Noise Protection
Inverter and SMPS in power part inside the servo drive operate
the switching operation in high frequency during the operation.
The di/dt,dv/dt (switching noise) which occurs by inverter
operation, are seldom affected by the connection and grounding
methods.
Wiring Precautions
Use the specified cables for encoder cable and command
input.
Keep the wiring distance as short as possible by cutting
off the excessive wire.
Wiring for grounding must be done with thick wire if pos-
sible. (More than 2.0 mm
Class 3 grounding (grounding resistance is lower than
100Ω ) is recommended.
One point grounding must be done. In other words, do
not make the loops.
Make sure there is no bending or tensions in the wire.
Make sure to connect the Earth terminal (PE) of the motor
and the servo drive.
Do not connect the unused signal wire.
Use noise filter in radio noise.
Servo drive is for the industrial use and does not include
the radio noise protection.
