Remark
：
Be sure that the signal ground of the upper computer should be connected with the ground of
power supply, and shielded twisted-pair cables should be used to reduce noise. The
maximum withstand voltage of drive internal transistor is DC 30V, and the maximum
allowable input current is 40mA.
4.5 CN2, CN3 communication terminal wiring
Drive is connected with the upper computer by CN2, CN3. Users can operate the drive by MODBUS communication, and the communication
distance is about 15m. RS485 can support multiple drives simultaneously online.
Communication signal connectors CN2, CN3 are two same internal, parallel communication signal connectors

Remark
：
1)
After turn off control power, analog monitor output terminal may output voltage of about 5V during 10ms, please note it when using.
2)
The maximum output of analog terminal current is 1mA. The drive can be damaged is it is more than 1mA.
