For p1982 = 2:
This is used for synchronous motor with motor encoder with absolute data to check this data.
With p1982 = 2, each time the pulses are enabled it is checked whether the absolute position supplied from the
encoder does not exceed a deviation of 45 degrees to the identified pole wheel position.
Not possible for separately excited synchronous motors.
Dependency: Refer to: p0325, p0329, p1980, r1984, r1985, r1987, p1990
Note: For encoderless operation, the pole position identification routine is selected with p1780.6
r1984 PolID angular difference / PolID ang diff
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: -
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, p1982, r1985, r1987, p1990
Note: PolID: Pole position identification
When the pole position identification routine is executed several times using p1983, 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
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: -
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, p1982, r1984, r1987, p1990
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
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: -
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, p1982, r1984, r1985, p1990
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.
