SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Dependency: If a sine-wave filter is parameterized as output filter (p0230 = 3, 4), then only responses can be selected without
pulse frequency reduction (p0290 = 0, 1).
For a thermal power unit overload, an appropriate alarm or fault is output, and r2135.15 or r2135.13 set.
Refer to: r0036, r0037, p0230, r2135
Refer to: A05000, A05001, A07805
Caution: 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: The setting p0290 = 0, 2 is only practical if the load decreases with decreasing speed (e.g. for applications with vari-
able torque such as for pumps and fans).
Under overload conditions, the current and torque limit are reduced, and therefore the motor is braked and forbid-
den speed ranges (e.g. minimum speed p1080 and suppression [skip] speeds p1091 ... p1094) can be passed
through.
For p0290 = 2, 3, the I2t overload detection of the power unit does not influence the responses.
When the motor data identification routine is selected, p0290 cannot be changed.
Description: Sets the alarm threshold for power unit overtemperatures. The value is set as a difference to the tripping (shut-
down) temperature.
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.
Index: [0] = Heat sink temperature
[1] = Power semiconductor (chip) temperature
Dependency: Refer to: r0037, p0290
Refer to: A05000
Description: Sets the alarm threshold for the I2t power unit overload.
If this threshold is exceeded, an overload alarm is generated and the system responds as parameterized in p0290.
Dependency: Refer to: r0036, p0290
Refer to: A07805
Note: The I2t fault threshold is 100 %. If this value is exceeded, fault F30005 is output.
Description: Sets the fan run-on time after the pulses for the power unit have been canceled.
