Connection Example 5: Connecting to a SYSMAC Motion Control Unit
Precautions for Correct Use
The example shows a 3-phase, 200-VAC input to the drive for the main circuit power supply. Be
sure to provide a power supply and wiring conforming to the power supply specifications for the
drive in use.
Incorrect signal wiring can cause damage to units and the drive.
Leave unused signal lines open and do not wire them.
Connect terminals and wiring marked with an asterisk (*) when using an absolute encoder.
This wiring diagram is an example of X-axis wiring only. For other axes, connections must be
made in the same way with the drive.
Always short unused NC input terminals at the Motion Control Unit I/O connectors.
Make the setting so that the servo can be turned ON/OFF with the RUN signal.
