VLT AutomationDrive FC 301/302
Programming Guide
Parameter 30-72 PLM Min. Speed
Table 1090: Parameter 30-72 PLM Min. Speed
30-72 PLM Min. Speed
Default value: 25%
Conversion index: 0
This parameter shows the minimum detection speed above which the PLM algorithm is allowed to act. The speed is given in [%]
relative to parameter 1-25 Motor Nominal Speed.
Parameter 30-73 PLM Detection Factor
Table 1091: Parameter 30-73 PLM Detection Factor
30-73 PLM Detection Factor
Default value: 5
Conversion index: 0
This parameter gives a detection sensitivity factor for the PLM feature - a copper loss multiplier. The PLM flags a blocked motor
when the monitored energy throughout the time window is lower than the copper loss energy multiplied by this sensitivity param-
eter.
5.23.5 30-8* Compatibility (I)
The following parameter is only available in FC 302:
-
Parameter 30-80 d-axis Inductance
Parameter 30-80 d-axis Inductance (Ld)
Table 1092: Parameter 30-80 d-axis Inductance (Ld)
30-80 d-axis Inductance (Ld)
Default value: Size related
Conversion index: -6
Enter the value of the d-axis inductance. Obtain the value from the permanent magnet motor datasheet. The d-axis inductance
cannot be found by performing an AMA.
Parameter 30-81 Brake Resistor (ohm)
Table 1093: Parameter 30-81 Brake Resistor (ohm)
30-81 Brake Resistor (ohm)
Default value: Size related
Conversion index: -2
Set the brake resistor value in Ω. This value is used for monitoring the power to the brake resistor in parameter 2-13 Brake Power
Monitoring. This parameter is only active in drives with an integral dynamic brake.
