System Design and Installation
Since switching takes place inside the Servo Drivers, harmonic current leaks from the armature of the
motor. With inverter leakage breakers, harmonic current is not detected, preventing the breaker from
operating due to leakage current.
When selecting leakage breakers, remember to also add the leakage current from devices other than
the Servomotor, such as machines using a switching power supply, noise filters, inverters, and so on.
For details on leakage breakers, refer to the manufacturer’s catalog.
The following table shows the Servomotor leakage current for each Servo Driver model.
Note 1. The above leakage current is for cases where Servomotor power line length is less than 10
Note 2. The above leakage current is for normal temperature and humidity. (It varies depending on

H Improving Encoder Cable Noise Resistance
The OMNUC W Series uses serial encoders, with phase-S signals from the encoder. The phase-S com-
munications speed is 4 Mbits/s.
In order to improve the encoder’s noise resistance, take the following measures for wiring and installa-
tion.
• Always use the specified Encoder Cables.
• If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the
• Do not coil cables. If cables are long and are coiled, mutual induction and inductance will increase and
