201751 <location>SI Motion CU: eff.test error safe encoder
Message %1
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The DQ encoder used for the safety-relevant motion monitoring functions signals an effectiveness test
error.
Message value (r9749, interpret decimal):
1 - TFD bit in EncoderStatusWord2 set in last effectiveness test set
2 - Actual effectiveness test no. in last effectiveness test set smaller/greater than expected
3 - IG1/IG2 bits in EncoderStatusWord2 in last effectiveness test set longer than expected
4 - F1/F2 bits in EncoderStatusWord2 in last effectiveness test set not dynamized
5 - Effectiveness tests performed too frequently
6 - LS1/LS2 were not frozen during effectiveness test
7 - Effectiveness tests performed too rarely or not at all
Remedy: - check the encoder connection.
- replace the encoder.
This message can be acknowledged as follows:
- motion monitoring functions integrated in the drive: Via Terminal Module 54F (TM54F) or PROFIsafe
- motion monitoring functions with SINUMERIK: Via the machine control panel.
201796 <location>SI Motion CU: Wait for communication
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: The drive waits for communication to be established with SINUMERIK or TM54F to execute the safety-
relevant motion monitoring functions.
Note:
In this state, the pulses are safely suppressed.
Remedy: After a longer period of time, if the message is not automatically withdrawn, the following checks
should be made dependent on the communication:
For communication with SINUMERIK, the following applies:
- check additional messages that are present regarding PROFIBUS communication and resolve.
- check the correct assignment of the axes on the higher-level control to the drives in the drive unit.
- check the enable signal of the safety-relevant motion monitoring functions for the corresponding axis
on the higher-level control - and if required, set
For communication with TM54F, the following applies:
- check additional messages that are present regarding DRIVE-CLiQ communication with TM54F and
resolve.
- check the setting of p10010. All of the drive objects controlled by the TM54F must be listed.

tions integrated in the drive (Motor Module)), p10010 (SI drive object assignment)
201798 <location>SI Motion CU: Test stop running
Message -
value:
Drive object: SERVO, VECTOR
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The test stop is active.
Remedy: None necessary.
The message is withdrawn when the test stop is finished.
