Description
the rigidity of the mechanical characteristics of
the motor. You need to calculate the rated slip
frequency of the motor as follows:
△f=f
Of which, f is the rated frequency of the motor
b
2, corresponding to function code P12.02. n is
the rated rotating speed of the motor 2,
corresponding to the 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
frequencies, which may cause unstable motor
running, or even VFD overcurrent. You can
adjust the two function codes properly to
eliminate such phenomenon.
Setting range of P04.23: 0–100
Setting range of P04.24: 0–100
Setting range of P04.25: 0.00Hz–P00.03 (Max.
output frequency)
0: Disable
1: Automatic energy-saving run
In light-load state, the motor can adjust the
output voltage automatically to achieve energy
saving.
0: Keypad (determined by P04.28)

2: AI2
3: AI3
4: HDIA
5: Multi-step running
(The setting is determined by related
parameters in group P10.)
