Dependency: If a sine-wave filter is parameterized as output filter (p0230 = 3, 4), then only responses can be selected without
reducing the pulse frequency (p0290 = 0, 1, 10).
For a thermal power unit overload, an appropriate alarm or fault is output, and r2135.15 or r2135.13 set.
For p0290 = 10:
This response is only applicable for booksize power units.
For p0290 = 12, 13:
These responses are only applicable for booksize or blocksize power units.
Refer to: r0036, r0037, p0108, r0108, p0230, r2135
Refer to: A05000, A05001, A07805
Notice: If the thermal overload of the power unit is not sufficiently reduced by the actions taken, the drive is always shut
down. This means that the power unit is always protected irrespective of the setting of this parameter.
Note: Under overload conditions, the current and torque limit are reduced, and therefore the motor is braked and forbidden
speed ranges (e.g. minimum speed p1080 and suppression [skip] speeds p1091 ... p1094) can be passed through.
When the motor data identification routine is selected, parameter p0290 cannot be changed.
For p0290 = 0, 2, 12:
This is setting is only practical if the load decreases with decreasing speed (e.g. for applications with variable torque
such as for pumps and fans).
For p0290 = 2, 3, 12, 13:
The I2t overload detection of the power unit does not influence the response "Reduce pulse frequency".
For p0290 = 10, 12, 13:
The possible load duty cycles, calculated based on the previous model (p0290 = 0, 1, 2, 3) for booksize power units
cannot be transferred in every case. As a consequence, we recommend that you involve our application support
group for borderline cases when dimensioning.

VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
- [°C]
Description: Temperature alarm threshold for the difference from the chip and heat sink temperature in the thermal model.
Dependency: Refer to: r0037
Refer to: F30024
Note: The parameter is only relevant for chassis power units.
p0294 Power unit alarm with I2t overload / PU I2t alrm thresh
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Converter
Not for motor type: -
Min
10.0 [%]
Description: Sets the alarm threshold for the I2t power unit overload.
Drive:
If this threshold is exceeded, an overload alarm is generated and the system responds as parameterized in p0290.
Infeed:
When the threshold value is exceeded, only an overload alarm is output.
Dependency: Refer to: r0036, p0290
Refer to: A07805
Note: The I2t fault threshold is 100 %. If this value is exceeded, fault F30005 is output.
