C01711 SI Motion P1 (CU): Defect in a monitoring channel
Explanation For a crosswise comparison, the drive found a difference between input data or results of the monitoring
functions and initiated a STOP F. One of the monitoring functions no longer functions reliably, i.e. safe
operation is no longer possible.
If at least one monitoring function is active, then after the parameterized timer has expired, message C01701
"SI Motion P1 (CU): STOP B initiated" is output.
The message value that resulted in a STOP F is displayed in r9725. The message values described involve
the crosswise data comparison between the Control Unit and Motor Module.
If the drive is operated together with a SINUMERIK, the message values are written to Alarm 27001 of the
SINUMERIK 840D sl.
Remedy In general, the following applies:
The monitoring clock cycles in both channels must be checked to ensure that they are identical and if required,
they must be set the same.
For fault value = 0:
No error has been detected in this monitoring channel. Note the error message of the other monitoring
channel (for HM: C30711).
For fault value = 4:
The monitoring clock cycles in both channels must be checked to ensure that they are identical and if required,
they must be set the same.
Re fault value = 1 ... 999:
Check the crosswise compared parameters that resulted in the STOP F, if required, copy the Safety param‐
eters.
Carry out a POWER ON (power off/on) for all components.
Upgrade the Motor Module software.
Upgrade the Control Unit software.
Correct the encoder evaluation. The actual values differ due to mechanical faults (transmission belts, tra‐
versing to mechanical limit, wear and tolerance windows that have been set too narrow, encoder faults, ...)
For fault value = 1000:
Investigate the signal associated with the safety-related input (contact problems).
For fault value = 1001:
Carry out a POWER ON (power off/on) for all components.
Upgrade the Motor Module software.
Upgrade the Control Unit software.
For fault value = 1005:
Check the conditions for pulse enable.
For fault value = 1011:
For diagnostics, refer to parameter (r9571).
