compensation, the output frequency of the
drive is automatically adjusted according
to the load torque of the motor, which can
reduce the speed change of the motor
caused by load changes, as shown in the
figure.
2. Electric status: When the actual speed
is lower than the input speed, gradually
increase the compensation gain (FC.04).
3. Generation status: When the actual
speed is higher than the input speed,
gradually increase the compensation gain
(FC.04).
4. The filter time constant of slip
compensation. The shorter the filter time,
the faster the response, but too short will
easily cause oscillation and speed
instability.

1. The droop control is suitable for the
occasions where multiple drives drive the
same load. By setting this function,
multiple drives can reach a uniform
distribution of power when driving the
same load. Transmission gears are shown
in the following figure (5 drives drive the
conveyors of 5 motors)
