SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the time constant of the PT1 element to smooth the torque actual value.
The smoothed actual torque is compared with the threshold values and is only used for messages and signals.
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).
Description: The power (P) for point 1 on the Y coordinate of the flow characteristic is saved in p3320. Unit: %
Dependency: Refer to: p3321
Note: The reference value for power and speed is the rated power/rated speed.
The energy saved is displayed in r0041.
Description: The speed (n) for point 1 on the X coordinate of the flow characteristic is saved in p3321. Unit: %
Dependency: Refer to: p3320
Note: The reference value for power and speed is the rated power/rated speed.
The energy saved is displayed in r0041.
