Wiring and Connection
3.2.3 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. For details, refer to the manual of the connected command option module.
∗5. To turn the servomotor power ON, a safety device 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 plug (JZSP-CVH05-E, provided as
an accessory) inserted into the CN8.
Note: The functions allocated to the input signals /SI3, P-OT, N-OT, /SI0, /SI4, /SI5, and /SI6 and the output signals /SO1,
/SO2, and /SO3 can be changed by using the parameters. Refer to 3.3.1 Input Signal Allocations and 3.3.2 Output
Signal Allocation.
