It is used to set the source of the frequency upper limit, including digital setting (P0-12), AI,
pulse setting or communication setting. If the frequency upper limit is set by means of AI1, AI2,
Keyboard potentiometer, DI5 or communication, the setting is similar to that of the main
frequency source X. For details, see the description of P0-03.
For example, to avoid runaway in torque control mode in winding application, you can set the
frequency upper limit by means of analog input. When the AC drive reaches the upper limit, it will
continue to run at this speed.

(P0-10)
0.00 Hz
If the source of the frequency upper limit is analog input or pulse setting, the final frequency
upper limit is obtained by adding the offset in this parameter to the frequency upper limit set in
P0-11.

0.00 Hz
If the frequency reference is lower than the value of this parameter, the AC drive can stop,
run at the frequency lower limit, or run at zero speed, determined by P8-14.

Model
dependent
It is used to adjust the carrier frequency of the AC drive, helping to reduce the motor noise,
avoiding the resonance of the mechanical system, and reducing the leakage current to the earth
and interference generated by the AC drive.
