Application Notes

Adjustable Voltage
Operation

In Adjustable Voltage control mode, the output voltage is controlled
independently from the output frequency. The voltage and frequency
components have independent references and acceleration/deceleration rates.
Single-phase and three-phase output is possible with this feature. The Adjustable
Voltage mode is designed to operate on electro-magnetic loads - not typical AC
motors.

Typical applications include:

Linear Motors
Vibration Welding
Vibratory conveying
Electromagnetic Stirring
Induction Heating (400 Hz or lower)
Resistive Loads (dryers)
Power Supplies
