Design and Installation
When selecting contactors, take into consideration the circuit’s inrush current and the momentary maxi-
mum current. The Position Driver inrush current is 50 A, and the momentary maximum current is
approximately twice the rated current. The following table shows the recommended contactors.
Note 1. Leakage current values shown above are for motor power lines of 10 m or less. The values will
Note 2. Leakage current values shown above are for normal temperatures and humidity. The values
j Improving Encoder and Resolver Cable Noise Resistance
Signals from the encoder are A-phase, B-phase, or S-phase. The A-phase and B-phase frequency is
154 kHz, and the S-phase baud rate is 616K bits/s.
Signals from the resolver are analog voltage signals.
Follow the wiring methods outlined below to improve encoder/resolver noise resistance.

Select leakage breakers designed for inverters.
Since switching operations take place inside the Position Driver, high-frequency current leaks from
the armature of the Servomotor. With inverter leakage breakers, high-frequency current is not de-
tected, preventing the breaker from operating due to leakage current.
When selecting leakage breakers, also remember to 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 detailed information on how to select leakage breakers, refer to the catalogs provided by the
manufacturers.
The following table shows the Servomotor leakage currents for each Driver model.
Be sure to use dedicated encoder and resolver cables.
If lines are interrupted in the middle, be sure to connect them with connectors, making sure that the
cable insulation is not peeled off for more than 50 mm. In addition, be sure to use shielded wire.
