Wiring and Connecting SERVOPACKs
*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. You can enable this function with a parameter setting.
*4. The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with double insulation or
reinforced insulation.
*5. Refer to the following manual if you use a safety function device.
Σ-7-Series Σ-7S SERVOPACK with Analog Voltage/Pulse Train References Product Manual (Manual No.: SIEP
S800001 26)
If you do not use the safety function, insert the Safety Jumper Connector (provided as an accessory) into CN8
when you use the SERVOPACK.
*6. Always use line receivers to receive the output signals.
Note: 1. If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power
supplies, 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.
2. Default settings are given in parentheses.
