3.5. CN3 Wiring for the signal of the communication connector
CN3 Layout for the terminal of the communication connector
The drive is connected to the computer via the communication connector. The user uses the MODBUS
communication and combines with the assembly language to operate the drive. The user may also use
PLC and HMI to operate the drive. We offer two communication interfaces that are commonly used:
(1) RS-232 and (2) RS-485. The RS-232 is used more often. The communication distance is about 15
m. If using the RS-485, the transmission distance would be longer. The RS-485 can support
simultaneous connections for multiple drives.
