C30706 SI Motion P2: SAM/SBR limit exceeded
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Motion monitoring functions with set acceleration monitoring (p9306 = 3):
SAM - safe acceleration monitoring. After initiating STOP B (SS1) the velocity has exceeded the selected tolerance.
Motion monitoring functions with set brake ramp monitoring (p9306 = 1):
SBR - Safe brake ramp monitoring. 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 tolerance for 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)

value (processor 2)), p9382 (SI Motion brake ramp delay time (processor 2)), p9383 (SI Motion brake ramp
monitoring time (processor 2)), p9548 (SI Motion SAM actual velocity tolerance (Control Unit))
C30711 SI Motion P2: Defect in a monitoring channel
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When cross-checking and 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.
The following message values may also occur in the following cases if the cause that is explicitly mentioned does
not apply:
- synchronization error between processor 1 and processor 2.
Message value (r2124, interpret decimal):
0 ... 999: Number of the cross-checked data that resulted in this message. The significance of the individual message
values is described in safety message C01711.
1000: Watchdog timer has expired. Too many signal changes have occurred at the F-DI.
1001: Initialization error of watchdog timer.
1005: Pulses already suppressed for test stop selection.
1011: Acceptance test status between the monitoring channels differ.
1020: Cyc. communication failure between the monit. cycles.
1040: Pulses suppressed with active encoderless monitoring functions.
1041: Current absolute value too low (encoderless)
1042: Current/voltage plausibility error
1043: Too many acceleration phases
1044: Actual current values plausibility error.
6000 ... 6166:
PROFIsafe message values (PROFIsafe driver for PROFIBUS DP V1/V2 and PROFInet).
For these fault values, the failsafe control signals (failsafe values) are transferred to the safety functions.
The significance of the individual message values is described in safety message C01711 of the Control Unit.
See also: r9725 (SI Motion, diagnostics STOP F)
Remedy: Re message value = 1040:
- de-select encoderless monitoring functions, select and de-select STO.
- if monitoring function is active, issue "SLS" pulse enable within 5 s of de-selecting STO.
Re other message values:
- the significance of the individual message values is described in safety message C01711.
Note:
This message can be acknowledged via F-DI or PROFIsafe.
