It makes inverter output frequency self adjust within a setting range according motor load change to compensate slip
frequency to make motor keep constant speed. It effectively relieves the impact of load change to motor speed.
Slip compensation diagram
If it is used with the automatic torque boost function,the low frequency trait can be promoted obviously.100.0% slip
frequency compensation corresponds to the motor rated slip; it may cause the motor speed exceeds setting value when
the compensation value is set too large .Hence, [F08.15] setting need to be limited.Slip compensation filter time is to
filter the slip compensation to eliminate disturb signal. The longer filter time is, the stronger anti-disturb force is. The
shorter filter time is, the weaker anti-disturb force is. But respond speed will be quicker.
The slip compensation function needs to correctly input the motor nameplate parameters and learn the
parameters to achieve the best results.
F08.17
Surge suppression gain
Setting range: 0.0-900.0%
While the motor control mode F0.00=0 or 1,it is easily to appear motor current instability and motor speed oscillation

phenomenon in medium and high power occasions , which is a combination of electrical and mechanical effects of
low-frequency resonance. It is possible to suppress the low frequency resonance by adjusting the [F08.17], but
excessive suppression gain may lead to additional stability problems.

Auto energy save selection:
Under the condition of light load, the motor can adjust the output voltage automatically after entering the constant
speed to promote the efficiency to save energy.
0: OFF
1: ON
Energy saving frequency lower limit:
When output frequency is lower than this value, auto energy save function will exit.
Energy saving voltage lower limit:While automatically saving energy running,the lower limit of the voltage can
reduce.100.0% is corresponding to the current output voltage corresponding to the output frequency without saving
energy.
Energy saving voltage regulation rate:
The rate of voltage regulation during the process of energy saving.
Energy saving voltage recovery rate:
The rate of voltage recovery to the normal voltage while exit the energy saving process.
Note: Enter energy saving only at constant speed running, hence this function is not suitable to be used in
occasions where the given frequency changes frequently.
