SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
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 gener-
ated 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 excessively
high heat sink temperature).
For values less than 1 s, a 1 s run on time for the fan is effective.
Description:
If the DC link voltage falls below this threshold, the power unit is shut down due to a DC link undervoltage condition
(F30003).
Dependency:
Refer to: p0278
Refer to: F30003
Description:
If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to DC link overvoltage.
Dependency:
Refer to: F30002
