Working Principle After inserting into the inverter expansion slot, the board is powered by internal DC5V. The upper PLC sends frequency reference and run command over the fieldbus; the board converts bus data to internal inverter control signals to modify frequency and start/stop. Running status, current, voltage, and fault codes are uploaded via the board. DIP switches set node address. LEDs indicate data transmit/receive.
Installation Requirements
- With inverter input power off, open cover and insert board into expansion slot
- Connect bus cable to inverter external bus terminals
- Set node address by DIP switches
- Terminate both ends of bus with 120 Ω resistor
- After re-power, select communication protocol in parameter menu
- Cabinet temperature -10 °C to +50 °C
- Verify bus address uniqueness after power-up
Precautions
- Install or remove the board only with input power disconnected
- Wait for internal capacitor discharge before service
- Use shielded twisted pair for bus cable
- Node addresses must not duplicate other devices on the bus
- Check protocol selection and termination resistor on communication faults
- Store spares in anti-static packaging
