201691 <location>SI Motion: Ti and To unsuitable for DP cycle
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The configured times for PROFIBUS communication are not permitted and the DP cycle is used as
the actual value acquisition cycle for the safe movement monitoring functions:
Isochronous PROFIBUS: the total of Ti and To is too high for the set DP cycle. The DP cycle should
be at least 1 current controller cycle greater than the sum of Ti and To.
Non-isochronous PROFIBUS: the DP cycle must be at least 4 x current controller cycle.
Remedy: Configure Ti and To low so that they are suitable for the DP cycle or increase the DP cycle time.
Option for enabled drive-based SI monitoring (p9601/p9801 > 0):
Use the actual value sampling cycle p9511/p9311 and, therefore, set it independently of the DP cycle.

201696 <location>SI Motion: Testing of the motion monitoring functions
selected when booting
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The test of the motion monitoring functions was already illegally active when booting.
This is the reason that the test is only carried out again after selecting the forced checking procedure
parameterized in p9705.
Note:
This message does not result in a safety stop response.
See also: p9705 (SI Motion: Test stop signal source)
Remedy: De-select the forced checking procedure of the safety motion monitoring functions and then select
again.
The signal source for initiation is parameterized in binector input p9705.
Note:
SI: Safety Integrated
See also: p9705 (SI Motion: Test stop signal source)
201697 <location>SI Motion: Motion monitoring functions must be tested
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The time set in p9559 for the forced checking procedure of the safety motion monitoring functions has
been exceeded. A new test is required.
After next selecting the forced checking procedure parameterized in p9705, the message is withdrawn
and the monitoring time is reset.
Note:
This message does not result in a safety stop response.
See also: p9559 (SI Motion forced checking procedure timer (Control Unit)), p9705 (SI Motion: Test
stop signal source)
Remedy: Carry out the forced checking procedure of the safety motion monitoring functions.
The signal source for initiation is parameterized in BI: p9705.
Note:
SI: Safety Integrated
See also: p9705 (SI Motion: Test stop signal source)
