p0629[0...n] Stator resistance reference / R_stator ref
CUG120XA_USS
(PM330)
Access level: 3 Calculated: CALC_MOD_EQU Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: -
Min:
0.00000 [ohm] Max:
2000.00000 [ohm] Factory setting:
0.00000 [ohm]
Description: Reference value for the identification of the stator resistance every time the drive is switched on.
Dependency: The measurement of the reference value is activated by the automatic calculation (p0340 = 1, 2), if the following
conditions apply:
- the motor temperature is at this instant in time less than 30 °C (r0035).
- a temperature sensor is not being used (p0601).
See also: p0621
Note
The reference value to identify the stator resistance is determined at the first identification. This must be realized when
the motor is in a cold state, as the value refers to the ambient temperature p0625. The feeder cable resistance should
be entered into p0352 before the measurement.
The result must be saved after the first measurement so that the reference is available after the CU has powered up.
When changing p0350 or p0352, the reference value p0629 should be re-determined.

p0640[0...n] Current limit / Current limit
Access level: 2 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: C2(1), T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6640, 6828
Min:
0.00 [Arms] Max:
10000.00 [Arms] Factory setting:
0.00 [Arms]
Description: Sets the current limit.
Dependency: See also: 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).
