System Architecture & Signal Flow
The ATV340D11N4 accepts a 3-phase 380–480V AC supply at the L1/L2/L3 input terminals. The internal rectifier converts AC to a regulated DC bus, which feeds the IGBT inverter stage. The inverter synthesizes a variable-frequency, variable-voltage output (U/V/W) to the motor. Speed reference is accepted via analog input (0–10V / 4–20mA), digital preset speeds, or fieldbus command. The integrated Modbus RTU port (RJ45) enables direct connection to a PLC or HMI for remote monitoring and parameter adjustment. The built-in braking transistor connects to an external resistor (customer-supplied) across the DC bus terminals for regenerative energy dissipation.

Technical FAQ
Q: Is the ATV340D11N4 compatible with single-phase input?
A: No. The D11N4 suffix denotes a 3-phase (N4 = 380–480V) input drive. For single-phase applications, refer to the ATV340 U-series.
Q: Can I use the built-in braking transistor without an external resistor?
A: The transistor is present but requires an external braking resistor to dissipate regenerative energy. Operating without a resistor during braking will trigger a DC bus overvoltage fault.
Q: What fieldbus options are available?
A: Modbus RTU is built-in. EtherNet/IP, Profibus DP, and CANopen are available via optional plug-in communication cards (VW3A3xxx series).
Q: Does the drive support PID control?
A: Yes. The ATV340 includes an integrated PID controller for closed-loop process control (e.g., pressure or flow regulation) without an external PLC.
Q: What is the derating policy above 1000m altitude?
A: Above 1000m, derate output current by 1% per 100m additional altitude up to a maximum of 3000m.
