FAQ
1. What is the main function of the Schneider ATV340D18N4?
The ATV340D18N4 is a variable-speed drive from the Altivar Machine ATV340 series, designed to regulate the speed and torque of three-phase motors. It is rated for 18.5 kW heavy-duty applications and 22 kW normal-duty applications. It provides controlled acceleration and deceleration, adjustable speed operation, motor protection and integration with industrial automation systems.
2. What power supply is required for the ATV340D18N4?
The ATV340D18N4 requires a three-phase 380–480 V AC power supply with a 50–60 Hz frequency. The permitted supply voltage range is -15% to +10%. Before commissioning, the incoming voltage, phase balance, grounding, upstream protection and cable selection should be checked. The drive rating should also be matched to the motor’s actual current and operating duty.
3. What is the heavy-duty motor rating of the ATV340D18N4?
The ATV340D18N4 is rated for an 18.5 kW motor under heavy-duty conditions, equivalent to approximately 25 hp. Its nominal output current is 39 A. Under normal-duty conditions, the drive can be applied to a 22 kW motor. The correct duty rating should be determined from the machine load profile, starting requirements and motor current rather than from motor power alone.
4. Which types of motors are supported by the ATV340D18N4?
The drive supports three-phase asynchronous motors as well as synchronous motors. It provides different motor-control profiles for applications with different torque and speed requirements. During commissioning, the motor nameplate values should be entered accurately. Proper motor parameter configuration is particularly important when vector control is used, as incorrect data can result in unstable speed regulation, excessive current or reduced torque performance.
5. What communication interfaces can be used with the ATV340D18N4?
The ATV340D18N4 provides Modbus serial communication and supports optional communication modules for networks such as PROFIBUS DP V1, PROFINET, DeviceNet, CANopen and EtherCAT. In a PLC-based automation system, communication can be used for start/stop commands, speed references, drive status monitoring, actual operating values and fault diagnostics. The PLC and drive configurations must use compatible communication parameters and data mapping.
6. Why does the ATV340D18N4 trip on overcurrent during motor acceleration?
Acceleration overcurrent can occur when the mechanical load is too high, the acceleration ramp is too short, motor parameters are incorrect, or the motor or mechanical system has a fault. Check the displayed fault code and motor current first. Verify the motor nameplate settings and inspect the driven equipment for excessive resistance or blockage. If the mechanical system is normal, increasing the acceleration time can reduce the current peak during startup.
7. What should be checked if the ATV340D18N4 receives a PLC command but the motor does not start?
First confirm that there is no active drive fault and that the STO safety circuit is correctly enabled. Then verify the configured command source and speed-reference source. If the PLC is responsible for control, check that it is transmitting the correct control command and a valid speed reference. Communication status, network configuration and parameter mapping should also be checked. A zero frequency reference or an incorrect command channel can prevent the motor from starting even when communication is working correctly.
8. What precautions are required when replacing an ATV340D18N4?
Disconnect the incoming power before replacement and wait until the DC bus has fully discharged. Record the existing motor settings, control mode, command source, reference source, communication parameters and protection settings before removing the original drive. After installation, verify the mains, motor, grounding and control wiring. Restore the required parameters and perform a controlled test run. Motor direction, acceleration, deceleration, output current, STO operation and PLC communication should all be confirmed before returning the machine to normal operation.
