r1797[0...n]

Motor model kT adaptation corrective value / MotMod kT corr

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, REL, FEM
Min
- [Nm/A]
Description: Displays the corrective value of the kT adaptation of the motor model for a permanent-magnet synchronous motor
(PEM).
Dependency: Refer to: p0826, p1780
Note: The display of the inactive data sets is only updated when changing over the data set.
p1798[0...n]

Motor model pulse technique speed adaptation Kp / MotMod PulsTech Kp

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, REL, FEM
Min
0.000
Description: Sets the proportional gain Kp for speed adaptation with active pulse technique for the estimation of the continuous
rotor position.
p1800[0...n]

Pulse frequency setpoint / Pulse freq setp

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
1.000 [kHz]
Description: Sets the pulse frequency for the converter.
This parameter is pre-set to the rated converter value when the drive is first commissioned.
Dependency: The pulse frequency can, depending on the current controller sampling time (p0115[0]) assume the following values:
p1800 = 1000 / (p0115[0] * 2)
or
p1800 = n * 1000 / p0115[0] with n = 1, 2, 3, ...
Example:
p0115[0] = 250 µs --> p1800 = 2, 4, 8, 12, 16 kHz
Possible setting values can be taken from r0114 (if p0009 = p0010 = 0).
If p0092 = 1 the sampling times p0115 and the pulse frequency p1800 are checked every time the parameters are
downloaded, and reset to the initial values if necessary. This check can be de-activated by setting p0092 = 0 (making
this setting does not affect isochronous PROFIBUS operation).
If the pulse frequency is set asynchronously to the current controller clock cycle (p1810.12),
then the following limit applies:
p1800 <= 1000 * 2 / p0115[0]
If wobbulation is selected (p1810.2), the pulse frequency can only be changed as part of pulse enabling to values
with the following ratio:
a) p1800 <= 1000 / p0115[0] for p1811 > 0 %
b) p1800 <= 1000 * 2 / p0115[0] for p 1811 = 0 %
Under pulse inhibit
p1800 > 1000 / p0115[0] -> p1811 = 0
p1800 > 1000 * 2 / p0115[0] -> 1810.2 = 0 and p1811 = 0
(applicable for all indices)
