FAQ
What types of motors can the VDN300 drive?
The VDN300 is exceptionally versatile. It is designed to provide high-performance current vector control for three main types of motors: standard asynchronous (induction) motors, permanent magnet synchronous motors (PMSM), and linear motors. This makes it a future-proof choice for facilities using different motor technologies.
What is the "Excavator" adaptive control feature?
This is a proprietary VDN300 feature inspired by the tough, variable loads of excavators. It actively monitors the motor’s operating condition and automatically limits torque when it detects a potential overload or stall condition. This intelligent function effectively suppresses frequent over-current trips, allowing machinery to continue operating smoothly rather than shutting down unexpectedly.
How does the VDN300 perform at very low speeds?
The VDN300 excels in low-speed applications. It is capable of stable operation with as low as 1% of the rated torque. This exceptional low-speed torque stability is critical for applications like precise positioning, tension control in winding processes, and smooth startup of high-inertia loads.
Can I switch between torque control and speed control?
Yes. The VDN300 supports bumpless switching between torque control and speed control modes. This allows for dynamic process changes, such as starting a machine in speed mode and then switching to torque mode for precise tension control during winding, without interrupting the operation.
