Technical Manual for EA350 Analog Pulse Type Servo Driver V101 3.5 CN2 and CN3 communication terminal wiring The driver is connected to the upper computer through the two identical communication signal connectors CN2 and CN3 connected in parallel inside of it; the user may operate the driver by MODBUS communication; the communication distance is about 15m. Table 3-10 Description of the communication connector pins Fig. 3-16 Wiring of communication terminals 3.6 CN1 analog output terminal Table 3-11 Instructions on analog output signals Precautions: 1) Upon turning OFF the control power, the analog monitoring output terminal might output a voltage of around 5 V in a period of up to 10 ms.
Please take it into account when using it. 2) The max. output current of the analog terminal is 1 mA. Any values beyond that might damage the driver. Please take full account when choosing the load.
