2 Parameters
2.2 List of parameters
This parameter describes the interdependency of the unsaturated component of the quadrature axis current.
Dependency: Refer to: p0634
p0636[0...n] Q flux direct axis current constant unsaturated / PSIQ KID UNSAT
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
0.00 [Arms]
Description: The non-linear and cross-coupled quadrature axis flux functions are defined using 4 coefficients.
This parameter describes the interdependency of the unsaturated component of the direct axis current.
Dependency: Refer to: p0634
p0637[0...n] Q flux flux gradient saturated / PSIQ Grad SAT
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
0.00 [mH]
Description: The non-linear and cross-coupled quadrature axis flux functions are defined using 4 coefficients.
This parameter describes the gradients of the saturated component over the quadrature axis current.
Dependency: Refer to: p0634, p0635, p0636
p0640[0...n] Current limit / Current limit
Access level: 2
Can be changed: C(1, 3), U, T
Unit group: -
Min
0.00 [Arms]
Description: Sets the current limit.
Dependency: Refer to: r0209, p0323
Note: The parameter is part of the quick commissioning (p0010 = 1); this means that it is appropriately pre-assigned when
changing p0305. The current limit p0640 is limited to r0209.
The resulting current limit is displayed in r0067 and if required, r0067 is reduced by the thermal model of the power
unit.
The torque and power limits (p1520, p1521, p1530, p1531) matching the current limit are automatically calculated
when exiting the quick commissioning using p3900 > 0 or using the automatic parameterization with p0340 = 3, 5.
p0640 is limited to 4.0 x p0305.
p0640 is pre-assigned for the automatic self commissioning routine (e.g. to 1.5 x p0305, with p0305 = r0207[1]).
p0640 must be entered when commissioning the system. This is the reason that p0640 is not calculated by the
automatic parameterization when exiting the quick commissioning (p3900 > 0).
p0641[0...n] CI: Current limit variable / Curr lim var
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for the variable current limit.
The value is referred to p0640.
