Siemens G130 List Manual page 445

Warning: For settings above 80%, the d current controller is active up to the field weakening limit. When operated at the
voltage limit, this can result in an unstable behavior. In order to avoid this, the dynamic voltage reserve p1574 should
be increased.
Note: The parameter value is referred to the synchronous rated motor speed.
p1731[0...n] Isd controller combination current time component / Isd ctr I_combi T1
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: PMSM, SESM, REL
Min
0.00 [ms]
Description: Sets the time constant to calculate the d current DC component difference (combination current) to add to the d
current controller actual value.
Note: It is not added for p1731 = 0.
r1732[0...1] CO: Direct-axis voltage setpoint / Direct U set
VECTOR_G (n/M) Can be changed: -

Not for motor type: REL
Min
- [Vrms]
Description: Display and connector output for the direct axis voltage setpoint Ud.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
r1733[0...1] CO: Quadrature-axis voltage setpoint / Quad U set
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [Vrms]
Description: Display and connector output for the quadrature axis voltage setpoint Uq.
Index: [0] = Unsmoothed
[1] = Smoothed with p0045
p1740[0...n] Gain resonance damping for encoderless closed-loop control / Gain res_damp
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
0.000
Description: Defines the gain of the controller for resonance damping for operation with sensorless vector control in the range that
current is injected.
