r1984 PolID angular difference / PolID ang diff
Access level: 4
Can be changed: -
Unit group: -
Min
- [°]
Description: Displays the angular difference between the actual electrical commutation angle and the angle determined by the
pole position identification.
Dependency: Refer to: p0325, p0329, p1980, r1985, r1987
Note: When the pole position identification routine is executed several times, the spread of the measured values can be
determined using this value. At the same position, the spread should be less than 2 degrees electrical.
r1985 PolID saturation curve / PolID sat_char
Access level: 4
Can be changed: -
Unit 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: -
Unit 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
perspective.
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
Unit 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).
