Have Questions? You May Not Be The Only One!

Here are some frequently asked questions about our VFD repair service:

Why use variable frequency drive for induction motor?

An induction motor has an advantage in controlling the voltage vector and developing the field weak. Here, although the control is a little more difficult, there is a steady improvement in the speed and computing power of modern processors.

The use of VFD is therefore good for induction motors as it maintains better overall control over the motors.

What if VFD is not installed properly?

If VFD is not installed properly, the following events may occur:

  • VFD will stop working on your device. This will stop responding to any action.
  • VFD may work but the value of the corresponding result will apparently start to deteriorate.
  • Your device may seem to be working but will keep tripping frequently.
  • VFD will only work after manual tuning.
How to choose the right frequency drive for motors?

Here are some important things to consider when choosing the right frequency drive for motors:

  • Description of application
  • Power distribution
  • Grounding
  • Electromagnetic interference
  • Communication policy
  • Wire and cable size
How to fix errors in variable frequency drive?

To fix errors in variable frequency drives, it is recommended to:

  • Look at the inertial load of the motor
  • Increase slow down ramp time
  • Set up progressive braking using a resistor and controller.
