Description: Displays the actual rotor resistance (phase value).
The parameter is affected by the motor temperature model.
Dependency: Refer to: p0354, p0620
Note: In each case, only the rotor resistance of the active Motor Data Set is included with the rotor temperature of the
thermal motor model.
This parameter is not used for synchronous motors (p0300 = 2xx).
Description: Sets the technology application.
The parameter influences the calculation of open-loop and closed-loop control parameters that is e.g. initiated using
p0340 = 5.
Value: 3: Pumps and fans, efficiency optimization
Notice: If the technological application is set to p0500 = 0 ... 3 during commissioning (p0010 = 1, 5, 30), the operating mode
(p1300) is pre-set accordingly.
Note: The calculation of parameters dependent on the technology application can be called up as follows:
- when exiting quick commissioning using p3900 > 0
- when writing p0340 = 1, 3, 5
For p0500 = 3 and when the calculation is initiated, the following parameters are set:
- p1574 = 2 V
- p1580 = 80 % (efficiency optimization)
- p1750.2 = 1: Encoderless control of the induction motor is effective down to zero frequency.
- p1802 = 10 (SVM/FLB with overmodulation and modulation depth reduction over 57 Hz)
- p1803 = 115 %
Description: Sets the technology application.
The parameter influences the calculation of open-loop and closed-loop control parameters that is e.g. initiated using
p0340 = 5.
Value: 0: Standard drive
1: Pumps and fans
2: Sensorless closed-loop control down to f = 0 (passive loads)
3: Pumps and fans, efficiency optimization
Notice: If the technological application is set to p0500 = 0 ... 3 during commissioning (p0010 = 1, 5, 30), the operating mode
(p1300) is pre-set accordingly.
Note: The calculation of parameters dependent on the technology application can be called up as follows:
- when exiting quick commissioning using p3900 > 0
- when writing p0340 = 1, 3, 5
