SA3100 Drive Configuration and Programming
2.4.2 Configuration Data - Setup (Volts per Hertz)
The Configuration Data - Setup parameter screen allows you to enter the following
information about the Volts per Hertz regulator. See figure 2.10.
• Asynchronous or Synchronous Carrier
The default is asynchronous carrier, which can be used for most applications.
Synchronous mode provides synchronization between the fundamental frequency
output from the drive and the carrier frequency. This causes minimal circulating
currents when inverters are swiched online.
Select Synchronous Carrier to cause the drive to synchronize the fundamental and
the carrier whenever the commanded frequency is greater than 15 Hz.
• Constant or Variable Torque
These buttons provide for the selection of the variable torque or constant torque
volts per hertz curve. The default is Constant Torque. When the Variable Torque
button is selected, the Constant Voltage Frequency, Motor Rated Frequency, and
Maximum Frequency fields are set to the same point.
• Unmodulated Six Step
Use this button to select the option of having the drive output an unmodulated six
step waveform when at maximum output voltage.
Unmodulated six step is defined as the lack of any modulating pulses in the output
waveform of the drive. Users who want maximum voltage output from the drive
should select this option.
