Note
Under certain circumstances, the inverter may reduce the switching frequency to provide
protection against over-temperature (see P0290, Level 3).
Minimum of pulse frequency depends on P1082 Max. frequncy and P0310 Rated Motor
frequency
Reverse output phase sequenceP1820
Changes direction of motor rotation without changing setpoint polarity.
Possible values
0= Normal
1 = Reverse phase sequence.

Select motor data identificationP1910
Performs stator resistance measuring.
Possible values:
0=No measurement – (P0350 setting will be used)
1=Stator resistance measurement - (Overwrites P0350 setting)
2=Stator resistance measurement. This does not overwrite the values already
calculated.– (original P0350 setting will be used)
Notes
Motor data must be correctly entered before stator resistance measurement is initiated.
Once enabled (P1910 =1) A0541 will be generated warning that the stator resistance
measurement will be performed at next ON command.
If setting 1 is selected, the manual/calculated value for the stator resistance (see P0350) is
overwritten.
If setting 2 is selected, the values already calculated are not overwritten.
