14.1 Working range monitoring, welded
Description The working range monitoring for axis 7 makes it possible to continuously
monitor the position of axis 7. It consists of cams (>>> Fig. 14-1), which are
attached by means of brackets to the beam of the linear unit, and position
switches, which are mounted on a holder fastened to the carriage. The work-
ing range monitoring system A7 allows up to six motion ranges to be moni-
tored on the linear unit.
A range is monitored by means of one position switch – or in the case of per-
sonnel protection, two position switches installed one behind the other – each
of which is actuated by one cam. Each position switch has a make contact and
a positively driven break contact.
The position switches are wired to connector X39 in accordance with the
number of monitoring ranges required by the user.
Connector X39 is the interface to the machine or system in which the linear
unit is integrated. It is located on the carriage. This interface is freely available
to the user of the machine or system. For working range monitoring with a per-
sonnel protection function, the wiring beyond the interface must be of failsafe
design, and is the sole responsibility of the user.
Caution!
Only the position switch type specified in (>>> 14.1.1 "Technical data"
page 108) may be used.
