ATV310 Ac Frequency Converter 0.37kW-30kW VFD Inverter 3 Phase

A: Absolutely. The ATV310 covers 0.37-30kW for normal-duty and 0.37-22kW for heavy-duty. For the 15kW heavy-duty conveyor belt, you can choose the ATV310D15N4; for the 22kW normal-duty exhaust fan, the ATV310D22N4 is suitable. Both models support vector control, meeting the precise speed regulation needs of the conveyor belt and the energy-saving operation requirements of the fan—no need to select different inverter series separately.

A: No. The ATV310's rated operating temperature for heavy-duty is -10℃-55℃. 50℃ falls within the rated range, allowing stable operation without derating. It can even work normally at a short-term maximum of 60℃, fully adapting to high-temperature workshop environments—no additional heat dissipation equipment is required.

A: It fully meets the requirement. The entire ATV310 series comes standard with vector control, enabling high-precision speed and torque regulation. It ensures stable start/stop and accurate speed for woodworking machinery spindles. Additionally, it's easy to operate—parameter configuration can be completed via a simple loader without professional programmers, significantly improving commissioning efficiency.

A: It depends on the start/stop frequency and load inertia. For normal intermittent start/stop (e.g., 1-2 times per minute), no external resistor is needed—the inverter's dynamic braking can meet the demand. For high-frequency start/stop (e.g., more than 3 times per minute) or large load inertia (such as the feeding roller of a packaging machine), it's recommended to match an external braking resistor to avoid delayed shutdown affecting production efficiency. The selection of the braking resistor can be further discussed based on equipment inertia.

A: Yes. The ATV310's coating complies with IEC60721-3-3 standards (3C3, 3S2), offering excellent anti-corrosion and moisture-resistant performance to adapt to outdoor dusty and slightly humid conditions. However, it's advisable to provide rain shielding during installation to avoid direct exposure to rain, further extending its service life.

A: It can connect directly with no extra modules required. The ATV310 comes standard with the Modbus communication protocol, which is fully compatible with the communication interfaces of existing equipment. Wiring is simple—just configure communication parameters (baud rate, address, etc.) according to standards to achieve centralized control, with no additional procurement costs.

A: The core difference lies in power segment and application scenario adaptation: the "U" suffix focuses on small-to-medium power general-purpose scenarios (e.g., small equipment of 0.37-7.5kW), while the "D" suffix is designed for medium-to-high power heavy-duty scenarios (e.g., heavy equipment of 11-30kW). Essentially, the 3kW "U" and "D" models have the same functions (both with built-in braking unit and vector control), but the "D" suffix model features enhanced heat dissipation design for long-term heavy-duty operation. If your equipment runs under continuous high load, the "D" suffix is more reliable; the "U" suffix is sufficient for normal loads.
