SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Displays the stator winding temperature of the motor temperature model.
Description: Displays the rotor temperature of the motor temperature model.
Note: For motor temperature model 3 (p0612.2 = 1), this parameter is not valid:
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).
Description: Sets the signal source for the variable current limit.
The value is referred to p0640.
