Description: Sets the integral time of the kT adaptation of the motor model for a permanent-magnet synchronous motor (PMSM).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Description: Displays the corrective value of the kT adaptation of the motor model for a permanent-magnet synchronous motor
(PMSM).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0826, p1780
Note: The display of the inactive data sets is only updated when changing over the data set.
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: Minimum pulse frequency: p1800 >= 12 * p1082 * r0313 / 60
Refer to: p0230
Note: The maximum and minimum possible pulse frequency is also determined by the power unit being used (minimum
pulse frequency: 2 kHz or 4 kHz).
When the pulse frequency is increased, depending on the particular power unit, the maximum output current can be
reduced (derating, refer to r0067).
If a sine-wave filter is parameterized as output filter (p0230 = 3), then the pulse frequency cannot be set below the
minimum value required for the filter.
For operation with output reactors, the pulse frequency is limited to 4 kHz (see p0230).
If p1800 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to
be set. The reason for this is that the dynamic limits of p1800 have been changed by a parameter that was set when
the drive was commissioned (e.g. p1082).
The pulse frequency cannot be changed when the motor data identification is activated.
