3.3 I/O Signals
This section describes I/O signals for the SERVOPACK with NS115.
3.3.1 Connection Example of I/O Signal Connector (CN1)
The following diagram shows a typical example of I/O signal connections.
* 1. P represents twisted-pair wires.
* 2. When using an absolute encoder, connect a backup battery only when
there is no battery connected to the CN8.
* 3. Make signal allocations using parameters. (Refer to 6.1.2 Standard
Settings for CN1 I/O Signals.)
