Si Motion Actual Value Sensing Sensorless Fault Tolerance (Cu); Si Motion Actual Value Sensing Sensorless Delay Time (Cu); Si Motion Actual Value Sensing Sensorless Filter Time (Cu) - Siemens SINAMICS G150 Manual

p9585 SI Motion actual value sensing sensorless fault tolerance (CU) / ActVal sl tol CU
VECTOR_G Can be changed: C2(95)
Data type: Integer32
P-Group: Safety Integrated
Not for motor type: -
Min
-1
Description: Sets the tolerance of the plausibility monitoring of the current and voltage angle.
A higher value results in a higher degree of ruggedness when reversing at low speeds, as well as in the field
weakening range for load steps.
An increase is advantageous, if the current or voltage at the motor become small.
Dependency: Refer to: r9787
Notice: Reducing this value can adversely affect the actual value sensing and the plausibility check.
When the value is increased, this results in a longer evaluation delay and a higher velocity deviation (r9787).
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
For synchronous motors, the value 4 must be set.
If value = -1:
- for synchronous motors, the calculation is automatically made with the value 4.
- for induction motors, the calculation is automatically made with a value of 0 (if the code number of the power unit
p0201[0] < 14000, otherwise with a value of 2).
p9586 SI Motion actual value sensing sensorless delay time (CU) / ActVal sl t_del CU
VECTOR_G Can be changed: C2(95)
Data type: FloatingPoint32
P-Group: Safety Integrated
Not for motor type: -
Min
5.00 [ms]
Description: Sets the delay time to evaluate the encoderless actual value sensing after the pulses have been enabled.
The value must be greater than or equal to the motor magnetizing time (p0346).
Caution: The safety functionality is only completely guaranteed after this time has expired.
Notice: If this value is reduced, this can have a negative impact on the actual value acquisition and plausibility check – and
result in Safety message C01711 with the message value 1041 or 1042.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
The set time is rounded internally to an integer multiple of the monitoring clock (p9500/p9300) cycle.
p9587 SI Motion actual value sensing sensorless filter time (CU) / Actv sl t_filt CU
VECTOR_G Can be changed: C2(95)
Data type: FloatingPoint32
P-Group: Safety Integrated
Not for motor type: -
Min
0.00 [ms]
Description: Sets the filter time for smoothing the actual value with sensorless actual value sensing.
Notice: A longer filter time results in a longer response time.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
The smoothing is realized with a 1st order lowpass filter
For p9587 = minimum value, the filter is deactivated.
The set time is rounded internally to an integer multiple of the monitoring clock (p9500/p9300) cycle.
