∗2. Connect when using an absolute encoder. When the encoder cable with the battery case is connected, do not connect
a backup battery.
∗3. Enabled by the parameter setting.
∗4. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-
tion.
∗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.
