3.2.3 Example of I/O Signal Connections
The following diagram shows a typical connection example.
∗1. represents twisted-pair wires.
∗2. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-
tion.
∗3. 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 JZSP-CVH05-E Plug (provided as an accessory) inserted into the CN8.
∗4. 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. Refer to 3.3.1 Input Signal Allocations and 3.3.2
Output Signal Allocations.
