2. Energy-saving running
In the actual operation, the VFD can search by itself to achieve a better effect point. The VFD can
work with high effect to save energy.
Note:
This function is usually used in the cases where the load is light or empty. If the load transients
frequently, this function is not appropriate to be selected.
3. V/F slips compensation gain
SVPWM control belongs to the open loop mode. If the load of the motor transients suddenly, the
fluctuation of the rotation speed may occur. In the cases where the high accuracy speed is needed,
slip compensation gain (internal output adjustment) can be set to compensate the speed change
caused by load fluctuation.
Setting range of slip compensation gain: 0–200%, of which 100% corresponds to rated slip frequency.
Note: Rated slip frequency= (rated synchronous rotation speed of the motor-rated rotation speed of
the motor) *number of pole pairs/60.
4. Vibration control
Motor vibration occurs frequently when applying SVPWM control mode in the cases where high
power is needed. In order to settle this problem, Goodrive35 series VFDs add two function codes
which are set to control the vibration factors. The user can set the corresponding function code
according to the vibration frequency.
Note: Bigger the set value, more effective is the control. If the set value is too big, overcurrent may
occur to the VFD.
