Parameters
7.2 Parameter list
Description:
Defines the rated overtemperature of the squirrel cage rotor referred to ambient temperature in the motor temperature
model 2 (p0612.1 = 1).
Dependency:
For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
See also: p0625
NOTICE
When selecting a standard induction motor listed in the catalog (p0300 > 100, p0301 > 10000), this parameter is
automatically pre-assigned and is write protected. Information in p0300 should be carefully observed when removing
write protection.
Note
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
p0629[0...n]
Stator resistance reference / R_stator ref
G120X_DP (PM330),
Access level: 3
G120X_PN (PM330),
Can be changed: T, U
G120X_USS (PM330)
Unit group: -
Min:
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, r0623
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.
