2.2 List of parameters
SINAMICS G120C
74 List Manual (LH13), 04/2014, A5E33840768B AA
Description: Displays the stator resistance determined using the Rs identification after switching on again.
Dependency: Refer to: p0621, p0622
Description: Defines the ambient temperature of the motor for calculating the motor temperature model.
Dependency: Refer to: p0350, p0354
Note: The parameters for stator and rotor resistance (p0350, p0354) refer to this temperature.
If the thermal I2t motor model is activated for permanent-magnet synchronous motors (refer to p0611), p0625 is
included in the model calculation if a temperature sensor is not being used (see p0601).
Description: Displays the stator winding temperature of the motor temperature model (models 2 and 3).
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.
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.
