r1985 PolID saturation curve / PolID sat_char
Access level: 4
Can be changed: -
Units group: -
Min
- [Arms]
Description: Displays the saturation characteristic of the pole position identification routine (saturation technique).
Displays the current characteristic of the pole position identification routine (elasticity technique).
Dependency: Refer to: p0325, p0329, p1980, r1984, r1987
Note: PolID: Pole position identification
Regarding the saturation technique:
The values for the characteristic of the last saturation-based pole position identification routine are output every 1
ms in order to record signals (e.g. trace).
r1987 PolID trigger characteristic / PolID trig_char
Access level: 4
Can be changed: -
Units group: -
Min
- [%]
Description: Displays the trigger characteristic of the pole position identification routine.
The values for the characteristic of the last pole position identification routine are output every 1 ms in order to
record signals (e.g. trace).
The values for trigger characteristic and saturation characteristic are always output in synchronism from a time per-
spective.
Dependency: Refer to: p0325, p0329, p1980, r1984, r1985
Note: PolID: Pole position identification
The following information and data can be taken from the trigger characteristic.
- the value -100% marks the angle at the start of the measurement.
- the value +100 % marks the commutation angle determined from the pole position identification routine.
p1999[0...n] Ang. commutation offset calibr. and PollD scaling / Com_ang_offs scal
Access level: 4
Can be changed: U, T
Units group: -
Min
10 [%]
Description: Sets the scaling for the runtime of the pole position identification technique in which the current is injected.
Dependency: Refer to: p0341, p0342
Caution: For p1999 > 100 % (setting large moments of inertia) the following applies:
There is no locked rotor monitoring (F07970 fault value 2).
Note: For high moments of inertia, it is practical to scale the runtime of the calibration higher.
