Function Code
P0-11 Source of frequency upper limit
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, AI3, 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.
Function Code
P0-12 Frequency upper limit
This parameter is used to set the frequency upper limit.
Function Code
Frequency upper limit
P0-13
offset
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.
Function Code
P0-14 Frequency lower limit
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.
Function Code
P0-15
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.
If the carrier frequency is low, output current has high harmonics, and the power loss and
temperature rise of the motor increase.
If the carrier frequency is high, power loss and temperature rise of the motor declines.
However, the AC drive has an increase in power loss, temperature rise and interference.
