10.3 DRIVE-CLiQ Hub Module External DME20

10.3 DRIVE-CLiQ Hub Module External DME20
10.3.1

Description

The DRIVE-CLiQ Hub Module External DME20, just like the DRIVE-CLiQ Hub Module
DMC20, is only used to connect direct measuring systems for the feed axes and expansion
axes of the S120 Combi.
The component has degree of protection IP67.
Note
The DME20 should also be used if only one feed axis is coupled with a direct measuring
system.
A fixed topology applies when assigning the particular feed axis to a DRIVE-CLiQ interface
(see Chapter "Topology rules for DRIVE-CLiQ") and this must be observed.

Safety information

NOTICE
In order to guarantee degree of protection IP67, all of the plug connectors must be correctly
screwed into place and appropriately locked.
NOTICE
The unused DRIVE-CLiQ ports must be closed using a cover that is included in the scope
of delivery.
Note
All components operated on the DRIVE-CLiQ must be integrated into the equipotential
bonding concept.
They should preferably be connected by installing them on bare metal machine parts and
devices, which are all bonded to one another in an equipotential manner.
Alternatively, equipotential bonding can be achieved by means of a conductor (min. 6 mm²),
which should be routed parallel to the DRIVE-CLiQ where possible. This applies to all
distributed DRIVE-CLiQ participants.
For the DME20 this also applies to the 24 V power supply.
