SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Diagnostic bits of absolute value encoder, motor measuring system
Minimum: Maximum:
0 4294967295
The serial number of the indirect, absolute measuring system is read from the
encoder in set state 3 at boot and entered in MD 5025. (Exception: Linear en-
coder.) 0 is entered if an incremental measuring system is installed. This en-
coder ID notifies the NC if the encoder has been replaced and, if it has been
replaced, the NC resets the calibration identifier.
Minimum: Maximum:
0000H FFFFH
