Description: Sets the stator resistance of the motor at ambient temperature p0625.
Dependency: Refer to: p0625, r1912
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The motor identification routine determines the stator resistance from the total stator resistance minus the cable
resistance (p0352).
Description: Resistance of the power cable between the power unit and motor.
Caution: The cable resistance should be entered prior to motor data identification. If it is used subsequently, the difference
by which p0352 was changed must be subtracted from the stator resistance p0350 or motor data identification must
be repeated.
Note: The parameter influences the temperature adaptation of the stator resistance.
The motor identification sets the cable resistance to 20% of the measured total resistance if p0352 is zero at the
time that the measurement is made. If p0352 is not zero, then the value is subtracted from the measured total stator
resistance to calculate stator resistance p0350. In this case, p0350 is a minimum of 10% of the measured value.
The cable resistance is reset when quick commissioning is exited with p3900 > 0.
Description: Sets the rotor/secondary section resistance of the motor at the ambient temperature p0625.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor data iden-
tification routine (p1910).
Dependency: Refer to: p0625
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The parameter is not used for synchronous motors (p0300 = 2).
