Siemens SINAMICS G120D List Manual page 869

Remedy: - remove the cause of the fault on the monitoring channel of processor 1.
- check the shutdown path of processor 2.
- carry out a diagnostics routine for message C30706.
- carry out a diagnostics routine for message C30714.
- carry out a diagnostics routine for message C30701.
- replace Power Module.
- replace Control Unit.
This message can be acknowledged via F-DI or PROFIsafe.
F-DI: Failsafe Digital Input
SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SBR: Safe Brake Ramp (safe brake ramp monitoring)
C30701 SI Motion P2: STOP B initiated
Reaction: NONE (OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP B (braking along the OFF3 deceleration ramp).
As a result of this fault, after the speed threshold parameterized in p9360 is fallen below, message C30700 "STOP
A initiated" is output.
Possible causes:
- stop request from processor 1.
- subsequent response to the message C30714 "SI Motion P2: Safely-Limited Speed exceeded".
- subsequent response to the message C30711 "SI Motion P2: Defect in a monitoring channel".
- subsequent response to the message C30707 "SI Motion P2: tolerance for safe operating stop exceeded".
Remedy: - remove the cause of the fault on the monitoring channel of processor 1.
- carry out a diagnostics routine for message C30714.
- carry out a diagnostics routine for message C30711.
- carry out a diagnostics routine for message C30707.
This message can be acknowledged via F-DI or PROFIsafe.
Note:
F-DI: Failsafe Digital Input
C30706 SI Motion P2: SAM/SBR limit exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Motion monitoring functions with set acceleration monitoring (SAM, p9306 = 3):
- after initiating STOP B (SS1) the velocity has exceeded the selected tolerance.
Motion monitoring functions with set brake ramp monitoring (SBR, p9306 = 1):
- after initiating STOP B (SS1) or SLS changeover to the lower speed stage, the speed has exceeded the selected
tolerance.
The drive is shut down by the message C30700 "SI Motion P2: STOP A initiated".
Remedy: Check the braking behavior and, if necessary, adapt the parameterization of the parameter settings of the "SAM" or
the "SBR" function.
This message can be acknowledged without a POWER ON as follows:
- motion monitoring functions integrated in the drive: via F-DI or PROFIsafe.
Note:
F-DI: Failsafe Digital Input
SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SBR: Safe Brake Ramp (safe brake ramp monitoring)
SI: Safety Integrated

value (processor 2)), p9382 (SI Motion brake ramp delay time (processor 2)), p9383 (SI Motion brake ramp monitor-
ing time (processor 2)), p9548 (SI Motion SAM actual velocity tolerance (processor 1))
C30711 SI Motion P2: Defect in a monitoring channel
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When cross-comparing the two monitoring channels, the drive detected a difference between the input data or results
of the monitoring functions and initiated a STOP F. One of the monitoring functions no longer reliably functions - i.e.
safe operation is no longer possible.
If at least one monitoring function is active, then message C30701 "SI Motion: STOP B initiated" is output.
