Industry Applications
Logistics & Warehousing
Adapts to various conveyors and travel drives, such as sorting conveyors in e-commerce warehouses and container transfer trolleys at ports. Precise speed control matches cargo handling rhythms, reducing jams or drops. Also used for lifting drives in warehouse shelving systems, ensuring stable elevation.
Packaging & Food Processing
Drives packaging machines for various products in automated packaging plants, adjusting speeds to match different packaging specifications. Suitable for mixing and filling equipment in food processing factories, balancing processing efficiency and product uniformity while meeting clean-in-place requirements.
Rubber, Plastic & Chemical Industries
Ideal for rubber and plastic extruders, stabilizing screw speeds to ensure consistent product thickness. Used for material transfer pumps in chemical processes, regulating flow rates to adapt to different production formulas.
General Machinery & Manufacturing
Adapts to spindle drives for machine tools and roller drives for printing presses. Suitable for fans, pumps, and other general equipment, saving energy via speed regulation to meet varying operational needs.
Hoisting & Lifting Equipment
Powers drive systems for cranes and lifting platforms. Its Safety Torque Off (STO) function (SIL3 rating) ensures operational safety, preventing accidental drops during lifting operations.
Frequently Asked Questions
Q: Our factory uses an EtherCAT bus control system--can this inverter integrate directly? Do we need to purchase additional modules?
A: No extra modules are required. It comes with built-in EtherCAT communication, plus support for Ethernet/IP, Profinet, and other mainstream protocols. Simply wire it to your control system. Note: If your inverter's firmware version is V7.0, firmware upgrades via the controller may fail. We recommend updating to V7.5 or later via the device's diagnostic interface first.
Q: We plan to install it in a Southeast Asian textile factory with high dust and humidity--can the IP20 protection withstand this environment?
A: Absolutely. Dust and moisture in textile factories cannot penetrate the IP20-protected structure. As a cabinet-mounted inverter, it will avoid dust accumulation on the surface (which affects heat dissipation) as long as the control cabinet door is properly closed. Many Southeast Asian textile factories use the same model to drive carding and spinning machines, with no failures caused by dust or moisture during long-term operation.
Q: We're purchasing 20 units in small batches and want models with motor temperature monitoring--does this function cost extra?
A: Motor temperature monitoring is a standard feature, no additional charge required. It has a dedicated monitoring interface; once wired, it provides real-time motor temperature data to prevent overheating damage. A 20-unit order also qualifies for a ~5% discount with distributors, with specific terms depending on the power models purchased.
Q: Our North American factory uses 3-phase 480V power--what model should we choose? Will there be voltage compatibility issues?
A: Select models labeled with 3AC 400 - 480V input (e.g., i55ae137f10v10000s). These models are compatible with North America's 480V industrial grid, eliminating the need for additional transformers. Many local small auto parts factories use the same model to drive component conveyors, with no voltage mismatch issues reported.
Q: We want to perform wireless commissioning--does this inverter support it? Is the operation complex?
A: Wireless LAN commissioning is supported, and operation is straightforward. Pair it with a dedicated operation panel or mobile app to remotely set parameters such as speed and start-up mode. An electrician at a small UK machinery factory completed wireless commissioning for 10 units in half a day, without the need for individual wiring or disassembly.
