SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Alarm value (r2124, interpret decimal):
Parameter number of the safety parameter which has changed, necessitating a POWER ON.
Remedy: - execute the function "Copy RAM to ROM".
- carry out a POWER ON (power off/on).
C30700 SI Motion P2: STOP A initiated
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP A (pulses are suppressed via the safety shutdown path of processor 1).
Possible causes:
- stop request from processor 1.
- Pulses not suppressed after test stop selection.
- subsequent response to the message C30706 "SI Motion P2: SAM/SBR limit exceeded".
- subsequent response to the message C30714 "SI Motion P2: Safely-Limited Speed exceeded".
- subsequent response to the message C30701 "SI Motion P2: STOP B initiated".
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.
