FAQ
What is the main difference between the VDN110 and the VDN60 series?
While both are compact drives for small power applications, they target different performance needs. The VDN60 focuses on Sensorless Vector Control (SVC) for higher starting torque and precision. The VDN110 focuses on high-performance V/F control with a modular, ultra-low temperature rise design and features like a built-in simple PLC, making it exceptionally reliable and easy to integrate into systems requiring basic logic control.
How does the low-frequency torque of the VDN110 compare to standard V/F drives?
Standard V/F drives often struggle to provide adequate torque at very low frequencies (below 5Hz). The VDN110 is specifically engineered to overcome this. As demonstrated in performance tests, it can deliver over 100% of the motor’s rated torque at just 1Hz, ensuring reliable starting and stable operation for applications that require high torque at low speeds.
What does "built-in simple PLC" mean, and how can I use it?
The built-in simple PLC function allows the VDN110 to execute a pre-programmed sequence of speeds and directions without requiring an external programmable logic controller. You can set up to multiple speed steps with individual run times and directions directly through the drive’s parameters. This is ideal for applications like simple cycling conveyors, mixers with soak cycles, or positioning tasks.
Can the VDN110 be used for closed-loop control applications?
Yes. The VDN110 features a built-in PID (Proportional-Integral-Derivative) controller. This allows it to be used for simple closed-loop process control, such as maintaining constant pressure in a small pumping system or constant tension in a winding application, by using an external sensor (e.g., pressure transducer or tension sensor) to provide feedback to the drive.
How fast can the VDN110 accelerate and decelerate?
The VDN110 is designed for excellent dynamic response. In performance tests, a 2.2kW VDN110 drive was able to stop a motor under heavy load in just 1.3 seconds. Acceleration and deceleration times are fully adjustable (from 0.1 to 6500 seconds) to match the requirements of your specific application.
