p0323[0...n] Maximum motor current / Mot I_max
Access level: 1 Calculated: - Data type: FloatingPoint32
Can be changed: C2(1, 3) Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: -
Min:
0.00 [Arms]
Max:
20000.00 [Arms]
Factory setting:
0.00 [Arms]
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.
p0325[0...n] Motor pole position identification current 1st phase / Mot PolID I 1st Ph
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [Arms]
Max:
10000.000 [Arms]
Factory setting:
0.000 [Arms]
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: See also: p0329, p1980, r1992
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).
p0327[0...n] Optimum motor load angle / Mot phi_load opt
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 6721, 6838
Min:
0.0 [°]
Max:
135.0 [°]
Factory setting:
90.0 [°]
Description: Sets the optimum load angle for synchronous motors with reluctance torque.
The load angle is measured at the rated motor current.
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.
