<location>SI Motion CU: Checksum error safety monitoring functions
Message value:
%1
Drive object:
SERVO_COMBI, SERVO_SINUMERIK828
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The actual checksum calculated by the drive and entered in r9728 via the safety-relevant parameters does not match
the reference 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 can be acknowledged.
Fault value (r0949, interpret decimal):
0: Checksum error for SI parameters for motion monitoring.
1: Checksum error for SI parameters for actual values.
2: Checksum error for SI parameters for component assignment.
Remedy:
- check the safety-relevant parameters and if required, correct.
- perform a POWER ON if safety parameters requiring a POWER ON have been modified.
- carry out an acceptance test.
Note:

<location>SI Motion CU: Incorrect parameter value
Message value:
Parameter: %1
Drive object:
SERVO_COMBI, SERVO_SINUMERIK828
Reaction:
OFF2
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The parameter cannot be parameterized with this value.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
Parameter number with the incorrect value.
The gearbox stage has been set to an excessively high value for the parameter 9522 fault value.
Remedy:
Correct the parameter value.
With hysteresis/filtering enabled (p9501.16=1), the following applies:
Set parameters p9546/9346 and p9547/9347 acc. to the following rule: p9546 >= 2 * p9547; 9346 >= 2 * p9347.
The following rule must also be adhered to when actual value synchronization (p9501.3 = 1) is enabled: p9549 <=
p9547; p9349 <= p9347.
Correct the parameter 9522 fault value.
Also check p9516.0 for fault value 9517.
