9-2 Configuration Example
This section describes the system configuration and provides a wiring example to the Servo Drive.
This section describes the example system configuration to implement the control described in the pre-
vious section with an NJ-series Controller, EtherCAT Coupler Unit, and Position Interface Units.
To construct a motor control system with a Pulse Output Unit, Digital Input Units are required to use
external sensors, such as for limit sensor inputs and error inputs.
A Digital Output Unit is used for a RUN output and an error reset output.
The Digital I/O Units are connected after the EtherCAT Coupler Unit in the same way as the Pulse Out-
put Unit.
The following diagram shows the example Unit configuration for the Controller.
