P12.02. n is the rated rotating speed of the
motor, corresponding to function code
P12.03. p is the number of pole pairs of the
motor. 100.0% corresponds to the rated slip
frequency △f of motor 2.
Setting range: 0.0–200.0%
In space voltage vector control mode, the
motor, especially the large-power motor,
may experience current oscillation at
certain frequencies, which may cause
unstable motor running, or even VFD
overcurrent. You can adjust the two
function codes properly to eliminate such
phenomenon.
