08/2005
Cause: The existing sensor module software does not support the safe motion monitoring function
with the higher-level control.
Note:
This fault results in a STOP A that cannot be acknowledged.
Remedy: - use a sensor module that supports safe motion monitoring function.
- upgrade the sensor module software.
Note:
SI: Safety Integrated
201680 <location>SI motion: Checksum error, safety monitoring functions
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The actual checksum calculated by the drive and entered in r9728 over the safety-relevant
parameters does not match the target checksum saved in p9729 at the last machine
acceptance.
Safety-relevant parameters have been changed or a fault is present.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal):
0: Checksum error for SI parameters for motion monitoring.
1: Checksum error for SI parameters for actual values.
Remedy: - Check the safety-relevant parameters and if required, correct.
- carry-out a POWER ON.
- carry-out an acceptance test.
Note:
SI: Safety Integrated
201682 <location>SI motion: Monitoring function not supported
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The monitoring function enabled in p9501 is not supported in this firmware version.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal):
1: Monitoring function SE (p9501.1).
2: Monitoring function SN (p9501.7 and p9501.8 - 15 and p9503).
3: Monitoring function SG override (p9501.5).
Remedy: De-select the monitoring function involved (p9501, p9503).
Note:
SE: Safe software limit switch
SG: Safely-reduced speed
SI: Safety Integrated
SN: Safe software cams

201683 <location>SI motion: SBH/SG enable missing
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The safety-relevant basic function SBH/SG is not enabled in p9501 although other safety-
relevant monitoring functions are enabled.
Note:
This fault results in a STOP A that cannot be acknowledged.
