The feature assures that the VLT® drive will limit motor current to prevent the motor to heat up.
Easy set-up
The feature is easy to use. In the control panel of the drive there is a parameter where you can enter relevant data from the motor nameplate. From this data, the drive creates a "loft" that limits the current provided dependant upon the motor speed.
Advantages of the new solution in a nutshell
The new feature offers more than just an economical and flexible alternative to existing solutions. It opens the way to attractive energy savings by increasing the cost effectiveness of speed controlled applications, especially pumps and fans.
Uncomplicated
Flexible use of speed control with motors having "Increased Safety" ignition protection.
Compact
Distinctly smaller frame size, lower weight and lower costs compared to speed control of motors with flameproof enclosures.
Flexible
Easy mix and match, resulting in smaller stocks of motors and converters.
Economical
Lower investment costs enable faster payback when speed control is used to achieve energy savings.
Universal
Universal solution for the power range of 0.4 to 1200 kW with 400, 500 or 690 V supply voltage.
NB!
No need for matched pairs
Suitable for operation of Ex-d/de and Ex-e motors without the need for matched pairs of motors and drives.
