SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
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.
Note: - Under certain circumstances, the fan can continue to run for longer than was set (e.g. as a result of the exces-
sively high heat sink temperature).
- For values less than 1 s, a 1 s run on time for the fan is active.
- for a PM230 power unit, sizes D - F the parameter is ineffective.
Description: Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage condition.
Dependency: Refer to: F30003
