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
