∗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. When using a safety function device, refer to 4.9 Safety Function. When not using a safety function device, leave the
safety function's jumper connector that is included with the SERVOPACK inserted in CN8.
∗5. Always use line receivers to receive the output signals.
Note: The functions allocated to the input signals /DEC, P-OT, N-OT, /EXT1, /EXT2, and /EXT3 and the output signals
/SO1, /SO2, and /SO3 can be changed by using the parameters. For details, refer to 3.3.1 Input Signal Allocations
and 3.3.2 Output Signal Allocations.
