SSI700 User Manual Description of Function Codes

• If P0-22 is set to 1, the frequency reference resolution is 0.1 Hz. In this case,
thesetting range of P0-10 is 50.0 to 3200.0 Hz.
• If 0-22 is set to 2, the frequency reference resolution is 0.01 Hz. In this case,
the setting range of P0-10 is 50.00 to 320.00 Hz.
Notes
After the value of P0-22 is modified, the frequency resolution of all frequency related function
codes change accordingly.

Source of frequency
upper limit
P0-11
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, DI5 or communication, the setting is similar to that of the main frequency source
A. 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) Frequency upper limit
offset
P0-13
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.

Frequency lower limit P0-14
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.

0.5–16.0 kHz Carrier frequency 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.
