1. The parameters F06.00 to F06.05 need to be adjusted carefully. They should
not be adjusted under normal circumstances.
2. While setting the switching frequency, note that the F06.04 switching
frequency 1 must be less than or equal to the F06.05 switching frequency 2.

Speed loop output filtering can reduce the impact on the current loop, but the value of
F06.07 should not be too large. Otherwise, slow responses may be caused. Use the default
settings under normal circumstances.

As the load increases, the rotor speed of the motor will increase. To make the rotor
speed close to the synchronous speed under the rated load, slip compensation can be
enabled. When the motor speed is less than the target value, the set value of F06.08 can be
