FAQ
What is the main difference between the VDN200 and the standard ECF100 series?
The VDN200 is a high-performance current vector drive, while the VDN100 is a general-purpose V/F and simple vector drive. The ECF200 features a faster DSP, more advanced control algorithms, and provides significantly higher performance: 180% torque at 0.5Hz (SVC), much faster torque response (<10ms), higher speed accuracy (0.2%), and a wider speed ratio (1:200). It is designed for applications requiring dynamic response and precision that standard drives cannot achieve.
Does the VDN200 support closed-loop vector control with an encoder?
Yes. The VDN200 series supports PG Vector Control (FVC) . By installing an optional PG (Pulse Generator) feedback card, the drive can operate in closed-loop mode. This enables 180% rated torque at 0Hz (zero-servo), ultra-high speed accuracy of 0.02%, and a dynamic response time of less than 10ms, making it suitable for the most demanding precision applications.
What does "180% torque at 0.5Hz" mean for my application?
This specification means the VDN200 can deliver 1.8 times the motor’s rated torque at a very low speed of just 0.5 Hz. For your application, this translates to extremely powerful starting capability. Equipment like heavy crushers, mixers, or conveyors that are fully loaded from a standstill can start smoothly and reliably without stalling or requiring an oversized motor.
How does the VDN200 protect itself and the motor?
The VDN200 includes a comprehensive suite of protection features. It has intelligent over-current, over-voltage, and overload suppression functions that actively prevent trips during transient conditions like rapid acceleration or sudden load changes, rather than just shutting down after a fault occurs. It also includes stall prevention, phase loss protection, and overheat protection for both the drive and the motor.
