The slip is 100% during the quick start with large inertia and 0 when the frequency
reaches the set value. Quick increase or decrease of the output frequency will cause
overvoltage or overcurrent. F05.12 filtering can slow down the rise of voltage and current.

Oscillation suppression cutoff

0.00-600.00 Hz 55.00
●
This parameter can be adjusted to suppress motor oscillations during the open loop
control (VVF). When the motor does not oscillate, this parameter should not be adjusted as
little as possible or properly reduced. If the motor oscillates obviously, this parameter can
be increased properly.

Droop control
frequency
0.00 - 10.00 Hz 0.00
●
This function is usually applied for load distribution when one load is driven by
multiple motors.
Droop control is to reduce the output frequency of the inverter with the load increasing,
so that the output frequency of the motor drops more in the load driven by multiple motors,
thus reducing the load on this motor and leading to evener distribution of the load on
multiple motors.
This parameter refers to the output frequency drop of the inverter under the rated load.

F05.17 Energy saving action time 1.00 - 60.00 s 5.00
●
The energy saving rate (F05.16) reflects the energy saving capacity. The larger the set
value, the more energy will be saved. If the set value is 0.00, energy saving will be invalid.
When energy-saving operation is valid, energy saving control will be enabled once the
energy saving conditions are met and have been maintained for the energy saving time
(F05.17).
