Parameters
List of Parameters
r1797[0...n]
Motor model kT adaptation corrective value / MotMod kT corr
Access level: 4
Can be changed: -
Units group: -
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.
p1800[0...n]
Pulse frequency setpoint / Pulse freq setp
Access level: 2
Can be changed: U, T
Units group: -
Min
2.000 [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:
Refer to: p0230
Note:
The maximum possible pulse frequency is also determined by the power unit being used.
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).
r1801[0...1]
CO: Pulse frequency / Pulse frequency
Access level: 2
Can be changed: -
Units group: -
Min
- [kHz]
Description:
Display and connector output for the actual converter switching frequency.
Index:
[0] = Actual
[1] = Modulator minimum value
Note:
The selected pulse frequency (p1800) may be reduced if the drive converter has an overload condition (p0290).
