4.2 Basic Wiring Diagrams
This section provide the basic wiring diagrams. Refer to the reference sections given in the diagrams for details.
*1. represents twisted-pair wires.
*2. Connect these when using an absolute encoder. If the Encoder Cable with a Battery Case is connected, do not
connect a backup battery.
*3. The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with double insulation or
reinforced insulation.
*4. Refer to the following chapter if you use a safety function device.
Chapter 11 Safety Functions
If you do not use the safety function, insert the Safety Jumper Connector (provided as an accessory) into CN8 when you use
the SERVOPACK.
*5. Always use line receivers to receive the output signals.
Note: If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power sup-
plies, such as the one for the I/O signals of the CN1 connector. If the power supply is shared, the I/O signals
may malfunction.
