SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the permissible speed deviation during load monitoring (for p2193 = 2).
Dependency: Refer to: r2169, p2181, p2193, p3230
Refer to: A07920, A07921, A07922, F07923, F07924, F07925
Description: Sets the signal source for detecting a failure.
Dependency: Refer to: p2192, p2193
Refer to: F07936
Note: Monitoring is triggered with a 0 signal, as soon as the time in p2192 has expired.
Description: Sets the time constant for the PT1 element to smooth the torque actual value.
The smoothed torque actual value is compared with the threshold values and is only used for messages and sig-
nals.
Description: Sets the monitoring time for phase failure detection of the motor.
Notice: After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: For p3235 = 0 the function is deactivated.
The monitoring is automatically de-activated during the flying restart operation for a motor that is still rotating.
3-phase phase failures cannot be detected and are indicated by other messages (e.g. F07902).
