P 4.2.1.1 Motor Type
Select the motor type. Select [0] Asynchronous Induction Motor, IM for asynchronous motors. Select [1] PM, Non-salient SPM or [3] PM,
Salient IPM for salient or non-salient PM motors. PM motors are divided into 2 groups, with either surface mounted (non-salient) or
interior (salient) magnets.
Default value:
0 [Asynchronous Induction Motor, IM]
Parameter

The following are the selections for the parameter.
Selection number Selection name
0 Asynchronous Induction Motor, IM
1 PM, Non-salient SPM
3 PM, Salient IPM
P 4.2.1.2 Number of Pole
Enter the number of motor poles.
Default value:
4
Parameter

Data type:
uint8
The dependency of the motor's synchronous speed ns in RPM of the frequency f of the supply in Hz (P 1.1.1 Grid Frequency) and the
number of pole pairs p in P 4.2.1.2 Nameplate Data are given by the following formula:
P 4.2.2.4 Nominal Frequency*120/P 4.2.2.5 Nominal Speed
For example, for a motor with 2-pole pairs (4 poles) and a frequency of the power supply of 50 Hz, the synchronous speed of the motor is
1500 RPM. The following table shows the number of pole pairs for normal speed ranges of various motor types.
