Benefit of VFD Use
Practical experience tells us that Easydrive VFD benefits your industrial automation system in 5 ways as listed below.
1. Ease of installation
The VFD is easily fitted between your low-voltage switch cabinet and motor. Its installation requires very simple wiring.
2. Simple operation
A straightforward DCS user interface allows for starting, stopping, frequency adjustment, and operating parameters monitoring operations.
3. Smooth motor control
Stepless speed control allows for wide-range speed adjustment. It also allows acceleration and deceleration to occur more smoothly with better precision.
4. Significant energy savings
Depending on the actual application need, our variable frequency drive usually operates at around 40Hz. Its actual electric current is no more than half of the rated value, thereby savings a significant amount of electricity.
5. Noise reduction
Due to low operating speeds, our VFD generates very little noise and produces lower than average heat.
