Sipos Absolute Encoder Errors - Siemens SINUMERIK 840C Installation Instructions Manual

12 Functional Descriptions
12.11.1 SIPOS absolute encoder up to SW 4

12.11.1.7 SIPOS absolute encoder errors

With SIPOS, errors can occur in the encoder as well as in the absolute submodule located on
the HMS measuring circuit module.
Please note that a faulty connection between the encoder and the absolute submodule can
trigger nearly all the error messages because it is along this connection that communication
takes place. This transmission line should therefore always be checked first when an error
occurs.
The following is a list of all possible error numbers together with the possible cause of error
provided that the connection between the encoder and the absolute submodule is not faulty:
