SINAMICS G130/G150
1546 List Manual (LH2), 07/2016, A5E03263479A
F07405 (N, A) Drive: Kinetic buffering minimum speed fallen below
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: During kinetic buffering the speed fell below minimum speed (p1257 or p1297 for vector drives with U/f control) and
the line supply did not return.
Remedy: Check the speed threshold for the Vdc_min controller (kinetic buffering) (p1257, p1297).
See also: p1257 (Vdc_min controller speed threshold), p1297 (Vdc_min controller speed threshold (U/f))
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07406 (N, A) Drive: Kinetic buffering maximum time exceeded
Message value: -
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF3 (IASC/DCBRK, NONE, OFF1, OFF2, STOP2)
Acknowledge: IMMEDIATELY
Cause: The maximum buffer time (p1255 and p1295 for vector drives with U/f control) has been exceeded without the line
supply having returned.
Remedy: Check the time threshold for Vdc-min controller (kinetic buffering) (p1255, p1295).
See also: p1255 (Vdc_min controller time threshold), p1295 (Vdc_min controller time threshold (U/f))
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F07407 Drive: Vdc reduction not permissible
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: For chassis power units, the reduction of the line voltage (see r0212.0) is only possible for closed-loop control of the
DC link voltage.
Remedy: - Activate DC link voltage control for the motor/generator.
- deactivate line voltage reduction (p0212.0 = 0).

A07409 (N) Drive: U/f control, current limiting controller active
Message value: %1
Message class: Application/technological function faulted (17)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The current limiting controller of the U/f control was activated because the current limit was exceeded.
