Note 1. Recommended connector (Hirose Electric)
Plug: TM10P-88P
Connection tool: CL250-0228-1
2. The final axis must be terminated between RDP (pin No. 3) and RDN (pin No.6) on the receiving side (servo amplifier) with a
150 resistor.
3. The overall length is 30m or less in low-noise environment.
4. The wiring between the branch connector and servo amplifier should be as short as possible.
5. Use the EIA568-compliant cable (10BASE-T cable, etc.).
6. Recommended branch connector: BMJ-8 (Hakko Electric Machine Works)
7. n 32 (Up to 32 axes can be connected.)
