2 Parameters
2.2 List of parameters
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 excessively
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
Description: Threshold to detect a DC link overvoltage.
If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to DC link overvoltage.
Dependency: Refer to: F30002
