represents twisted-pair wires.
∗2. Connect when using an absolute encoder. When the encoder cable with the battery case is connected, do not connect
a backup battery.
∗3. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-
tion.
∗4. For details, refer to the manual of the connected command option module.
∗5. When using the safety function, a safety function device must be connected and the wiring that is necessary to acti-
vate the safety function must be done to turn ON the servomotor power. When not using the safety function, use the
SERVOPACK with the Plug (provided as an accessory) inserted into the CN8.
∗6. Always use line receivers to receive the output signals.
Note: The functions allocated to the input signals /SI1, P-OT, N-OT, /SI4, /SI5, and /SI6 and the output signals
/SO1, /SO2, and /SO3 can be changed by using the parameters. Refer to 3.4.1 Input Signal Allocations and 3.4.2
Output Signal Allocations.

SERVOPACK
The number of pins on the CN1 connector is different on a large-capacity Σ-V SERVO-
PACK (50 pins) and a standard Σ-V SERVOPACK (26 pins). If you are using both types
of SERVOPACK, use the correct connector model numbers when ordering and the cor-
rect signal assignments.
