SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
For p0500 = 2 and the calculation is initiated, the following parameters are set:
p1574 = 2 V (for separately-excited synchronous motors: 4 V)
p1750 bit 2 = 1: Sensorless closed-loop control of induction motors effective up to a frequency of zero.
This operating mode is possible for passive loads. These include applications where the load does not generate
regenerative torque when breaking away and the motor comes to a standstill (zero speed) itself when the pulses
are inhibited.
p1802 = 4 (SVM/FLB without overcontrol) (PM240: p1802 = 0)
p1803 = 106 % (PM240: p1803 = 110 %)
The setting of p1750 is only relevant for induction motors.
p1802 and p1803 are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
For p0500 = 3 and the calculation is initiated, the following parameters are set:
- p1574 = 2 V
- p1750 bit 2 = 1: Sensorless closed-loop control of induction motors effective up to a frequency of zero.
- p1802 = 0 (SVM/FLB with overcontrol)
- p1803 = 115 % (PM240: p1803 = 110 %)
Description: Inhibits the calculation of reference parameters (e.g. p2000) when automatically calculating the motor and closed-
loop control parameters (p0340, p3900).
Value: 0: No
1: Yes
Notice: The inhibit for the reference value calculation is canceled when new motor parameters (e.f. p0305) are entered and
only one drive data set exists (p0180 = 1). This is the case during initial commissioning. Once the motor and control
parameters have been calculated (see p3900, p0340), the inhibit for the reference value calculation is automatically
reactivated.
Note: 0: The automatic calculation (p0340, p3900) overwrites the reference parameters.
1: The automatic calculation (p0340, p3900) does not overwrite the reference parameters.
Description: Sets the sensor type for the motor temperature monitoring.
Value: 0: No sensor
1: PTC alarm & timer
2: KTY84
4: Bimetallic NC contact alarm & timer
Dependency: The thermal motor model is only calculated for p0612.1 = 1.
Caution: If, for a selected KTY temperature sensor (p0601 = 2), the motor temperature sensor is not connected but another
encoder, then the temperature adaptation of the motor resistances must be switched out (p0620 = 0). Otherwise, in
controlled-loop operation, torque errors will occur that will mean that the drive will not be able to be stopped.
Note: PTC thermistor (p0601 = 1): Tripping resistance = 1650 Ohm.
