Electrical installation
Communication wiring
- Cable recommendation
EtherCAT bus communication uses STP/FTP cable for network data transmission, without short circuit, dislocation and bad contact.
The length of the cable between the devices cannot exceed 100 meters. Exceeding 100 meters will cause signal attenuation and affect normal communication.
It is recommended to use the following specifications of data cables:
| Item | Specifications |
|---|---|
| Type of cable | Elastic crossover cable, Category 5E (cat 5e) cable and above |
| Traverse cross section | AWG26 |
| traverse type | Twisted pair |
| Line pairs | 4 pairs |
- Wiring instructions
Wiring is carried out according to the radium engraving of the shell, where the IN interface is EtherCAT input port, which is used to connect the EtherCAT master station; The OUT interface is an EtherCAT output port, which is used to connect the later EtherCAT slave station.
Power terminal wiring
Connect the positive and negative electrodes of the 24V power supply according to the shell marks; The cross-sectional area of the grounding wire is not less than 2mm2, and the grounding resistance is less than 100Ω.
