SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
5.1.1 Measuring system
One position encoder for each axis can be evaluated on the module.
S X101: Axis 1
S X102: Axis 2
The measuring system must always be plugged into the connector of the asso-
ciated axis.
See Section 7.1 for further details.
Table 5-1 Connectors X101, X102; 15-pole male sub D connector (two-tier) in
each case
