I am working with VFD (CT-2002ES-A75). It shows output frequancy on it's seven segment display. However It has a parameter(Cd46 on page 27 in the manual) for display the current RPM of the motor.
For display the current RPM need to enter some factor as parameter input. How to calculate that scaling factor for my motor?
This is the nameplate of the motor that controlled by the VFD. Motor is connected as star system. Working on 230VAC supply.
