SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
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:
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 impressed.
Dependency:
Refer to: p0341, p0342
Caution:
For P1999 > 100% (setting, large moments of inertia):
There is no locked rotor monitoring (A7970.2).
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 in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
The following applies: Reference frequency (in Hz) = reference speed (in (rpm) / 60)
Dependency:
p2000 is only updated during automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning has been carried
out first for drive data set zero and as a result overwriting of the parameter has not been blocked by setting p0573 =
1.
Refer to: p2001, p2002, p2003, r2004
Note:
If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties 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 percent-
age input value is cyclically converted into the absolute speed setpoint using the reference speed (p2000).
Example 2:
The setpoint from PROFIBUS (r2050[1]) is connected to a speed setpoint (e.g. p1070[0]). The actual input value is
cyclically converted into a percentage value via the pre-specified normalization 4000 hex. This percentage value is
converted to the absolute speed setpoint via reference speed (p2000).
