Common setting of V/Hz curve.
• When setting to 1 or 2, the 2nd and the 3rd voltage frequency setting are invalid�
• If a motor load is a variable torque load (the torque is in direct proportion to the speed, such as
the load of a fan or a pump), the drive will decrease input voltage to reduce flux loss and iron loss
of the motor at low speed with low load torque to raise the overall efficiency�
• When setting the higher power V/Hz curves (selection #4 or #5), low frequency torque will be
even lower than General Purpose� Therefore it is not suitable for fast acceleration/deceleration� It
is recommended NOT to apply this parameter for any fast acceleration/deceleration�
