control. The inverter will adjust the torque boost according to the actual load.
Note:
The torque boost takes effect only when the frequency is under the cap frequency of the boost.
If the torque boost is too big, low frequency vibration or overcurrent fault may occur. Please lower
the torque boost.
2.
Energy-saving running
In the actual operation, the inverter can search by itself to achieve a better effect point. The
inverter 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 the 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, Goodrive200 series inverters 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 motor.
