2.2 List of parameters
Description: Sets the reluctance torque constant for synchronous motors with reluctance torque (e.g. 1FE ... motors).
This parameter has no significance for induction motors.
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: For synchronous motors without reluctance torque, the value 0 must be set.
Description: Sets the current for the pole position identification routine (p1980 = 1).
For a two-stage technique (p1980 = 4), the current is set for the 2nd phase.
The current for the 1st phase is set in p0325.
Dependency: The following applies for vector drives:
If a maximum current (p0323) was not parameterized, then p0329 is limited to the rated motor current.
Refer to: p0325, p1980, r1992
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Description: Displays the rated motor slip.
Dependency: The rated slip is calculated from the rated frequency, rated speed and number of pole pairs.
Refer to: p0310, p0311, r0313
Note: The parameter is not used for synchronous motors (p0300 = 2xx).
Description: Induction motor:
Displays the rated magnetizing current from p0320.
For p0320 = 0, the internally calculated magnetizing current is displayed.
Synchronous motor:
Displays the rated short-circuit current from p0320.
Dependency: If p0320 was not entered, then the parameter is calculated from the rating plate parameters.
