2.4.3 V/Hz Characteristic Screen (Volts per Hertz)
The V/Hz Characteristic parameter screen allows you to enter specific information
about the motor and V/Hz regulator. See figure 2.11.
• Maximum Frequency (Hertz)
Maximum Frequency defines the maximum frequency which will be output from the
drive. Resolution is 0.001 Hz.
• Constant Voltage Frequency (Hertz)
Constant Voltage Frequency is the frequency point on the volts per hertz curve that
marks the beginning of the constant voltage region. The voltage remains constant
for all frequencies at or above the constant frequency point. Resolution is 0.001 Hz.
• Motor Rated Frequency (Hertz)
Motor Rated Frequency is divided into Motor Rated Voltage to define the motor
rated V/Hz excitation. Resolution is 0.001 Hz.
• Motor Rated Voltage (Volts)
Motor Rated Voltage divided by Motor Rated Frequency defines the motor rated
V/Hz excitation. Enter the value in volts.
• Operating Volts/Hz (Volts/Hertz)
The Operating Volts/Hz entry represents the volts per hertz ratio value. The value
entered must be less than or equal to the Motor Rated Voltage divided by the Motor
Rated Frequency. If no value is entered, a default value equal to the Motor Rated
Voltage divided by the Motor Rated Frequency is provided. Resolution is 0.01V/Hz.
