4.2.3 Example of I/O Signal Connections
The following diagram shows a typical connection example.
∗1. represents twisted-pair wires.
∗2. Connect when using an absolute encoder. When the encoder cable for the battery case is connected, do not connect a
backup battery.
∗3. The 24-VDC power supply is not included. Use a power supply with double insulation or reinforced insulation.
∗4. To turn the servomotor power ON, a safety unit must be connected and the wiring to activate the safety function must
be done. When not using the safety function, use the SERVOPACK with the safety jumper connector (JZSP-CVH05-
E, provided as an accessory) inserted into the CN8.
