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).
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.
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.
Description: Sets the reference quantity for speed and frequency.
All speeds or frequencies specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
The following applies: Reference frequency (in Hz) = reference speed (in ((rpm) / 60) x pole pair number)
Dependency: This parameter is only updated during the automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning was
carried out beforehand for drive data set zero. This means that the parameter is not locked against overwriting using
p0573 = 1.
Refer to: p2001, p2002, p2003, r2004, r3996
Notice: When the reference speed / reference frequency is changed, short-term communication interruptions may occur.
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quantities
are used as internal conversion factor.
Example 1:
The signal of an analog input (e.g. r0755[0]) is connected to a speed setpoint (e.g. p1070[0]). The actual percentage
input value is cyclically converted into the absolute speed setpoint using the reference speed (p2000).
