7.4 SVPWM control

Goodrive35 series VFDs provide internal SVPWM control which can be used in the cases where it
does not need high control accuracy. It is also recommended to use SVPWM control when one VFD
drives multiple motors.
Goodrive35 series VFDs provide multiple V/F curve modes. The user can select the corresponding
V/F curve to the site needs. Or they can set the corresponding V/F curve to their own needs.
