the next slave station; if need not, add balance resistor in CN4 terminal.).It is prohibited to connect CN3 of any two servo
drives directly when multiple ProNet series servo drives are connected.
Example:
When a RS-485 network is composed of a PLC and three servo drives (A, B, and C), the cable wiring is shown as follows:
PLC→CN3 of A, CN4 of A→CN3 of B, CN4 of B→CN3 of C, CN4 of C→120Ω terminating resistance.
In the case of ProNet-□□□EG-EC servo drives, the communication method is using the standard mini-USB port. By
using the CP2102chip, it converts the RS232 communication to USB communication. Thus, it is necessary to install the
CP2102 drive in the host computer. In addition, the definitions of the communication connector terminals are as follows.
