Description: Stator resistance value in [Ohms] for connected motor (line value).
The parameter value doesn't include the cable resistance.
There are three ways to determine the value for this parameter:
1. Calculate using
- P0340 = 1 (data entered from rating plate) or
- P0010 = 1, P3900 = 1, 2 or 3 (end of quick commissioning).
2. Measure using P1900 = 2 (standard motor data identification - value for stator resistance is overwritten).
Measure using P1900 = 3 (compleate motor data identification - same like setting 2; additional detection of the
saturation curve)
3. Measure manually using an Ohmmeter.
Note: Since the manually measured resistor is a line-to-line value, which includes the cable resistors, the measured value
has to be divided by two and the cable resistor of a line has to be subtracted from that value.
The value entered in P0350 (stator resistance) is the one obtained by the method last used.
Default value is depending on inverter type and its rating data.
Description: Describes cable resistance between inverter and motor for one phase.
The value corresponds to the resistance of the cable between the inverter and the motor, relative to the rated
impedance.
Description: Sets rotor resistance of motor equivalent circuit (phase value).
Dependency: Calculated automatically using the motor model or determined using P1900 (motor identification).
Description: Sets stator leakage inductance [mH] of motor equivalent circuit (phase value).
Dependency: Calculated automatically using the motor model or determined using P1900 (motor identification).
