68 List Manual (LH11), 01/2016, A5E33839529
Description: Sets the maximum permissible motor current (e.g. de-magnetizing current for synchronous 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.
If p0323 is changed during quick commissioning (p0010 = 1), then the maximum current p0640 is pre-assigned
accordingly.
Note: The parameter has no effect for induction motors.
The parameter has not effect for synchronous motors if a value of 0.0 is entered. The user-selectable current limit is
entered into p0640.
Description: Sets the current for the 1st phase of the two-stage technique for pole position identification routine.
The current of the 2nd phase is set in p0329.
The two-stage technique is selected with p1980 = 4.
Dependency: Refer to: p0329, p1980, r1984, r1985, r1987
Refer to: F07969
Notice: When the motor code (p0301) is changed, it is possible that p0325 is not pre-assigned.
p0325 can be pre-assigned using p0340 = 3.
Note: The value is automatically pre-assigned for the following events:
- For p0325 = 0 and automatic calculation of the closed-loop control parameters (p0340 = 1, 2, 3).
- for quick commissioning (p3900 = 1, 2, 3).
Description: Sets the correction factor for the stall torque/force at a 600 V DC link voltage.
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: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
Description: Sets the optimum load angle for synchronous motors with reluctance torque.
The load angle is measured at the rated motor current.
