Stator resistance reference / R_stator ref

VECTOR_G (n/M) Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: PEM, REL, FEM
Min
0.00000 [ohm]
Description: Reference value for the identification of the stator resistance every time the drive is powered up.
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 KTY temperature sensor is not being used (p0601).
Refer to: p0621, r0623
Note: The reference value to identify the stator resistance should be manually entered after the first identification (p0629 =
r0623). The identification 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 a powered
up. When changing p0350 or p0352, the reference value p0629 should be re-determined.
