SCHNEIDER ATV930
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang SCHNEIDER ATV930 dari 3G Electric.
What are the input voltage and phase requirements for the Schneider ATV930 drive?
The Schneider ATV930 variable speed drive requires a three-phase input voltage of 380-480V AC. This is consistent across all models in the series, as seen in the SKUs stocked by 3G Electric, such as the ATV930U22N4US and ATV930C13N4CUS. The output is also three-phase, making it suitable for standard industrial three-phase induction motors. Ensure your facility's supply matches this voltage range and phase configuration before installation.
What is the maximum output current and horsepower range for the ATV930 series?
The ATV930 series covers a wide range of output currents and horsepower ratings. Based on the SKUs available from 3G Electric, the smallest model (ATV930U22N4US) delivers 5.6 A output current and is rated for 3 hp. The largest model (ATV930C13N4CUS) provides 250 A output current and is rated for 200 hp. Intermediate models include 9.3 A (5 hp), 16.5 A (10 hp), 31.7 A (20 hp), 145 A (100 hp), and 173 A (125 hp). This range allows selection for various motor sizes.
Does the Schneider ATV930 drive support closed-loop control with an encoder?
Yes, the ATV930 supports closed-loop flux vector control when used with an encoder feedback option. This mode provides high dynamic performance and precise speed regulation, suitable for applications like hoists or winders. The drive also offers sensorless flux vector control and standard V/F control. The encoder interface is available via optional plug-in modules, and the drive's control board includes dedicated inputs for encoder signals.
What communication protocols are available on the ATV930 drive?
The ATV930 comes with embedded communication ports including Modbus serial (RS-485) and CANopen. It also has an Ethernet port supporting Modbus TCP/IP. For additional protocols like PROFIBUS DP, DeviceNet, or EtherNet/IP, optional fieldbus modules can be inserted into the drive's expansion slot. This flexibility allows integration into various industrial automation networks.
What is the protection rating (IP) of the ATV930 chassis-style drives?
The chassis-style ATV930 drives, such as the ATV930U55N4US, are typically rated IP21, providing protection against solid objects larger than 12 mm and dripping water. Some models may have higher IP ratings if ordered with an enclosure option. For environments with higher dust or moisture, consider adding an external enclosure or selecting a drive with a higher IP rating from the ATV900 family.
Can the ATV930 be used for pump and fan applications with energy savings?
Yes, the ATV930 is well-suited for pump and fan applications. It includes built-in PID controllers for pressure or flow regulation and energy consumption monitoring. The drive supports variable torque load profiles, which can reduce energy consumption by up to 50% compared to fixed-speed operation. Features like sleep/wake mode and automatic energy optimization further enhance efficiency in HVAC and water treatment systems.
