Wiring
The SINUMERIK 840D and the HLA module are supplied from the
SIMODRIVE line supply infeed or from the SIMODRIVE monitoring module via
the equipment bus. There must be at least one NE module in the equipment
group when an HLA module is used. No provision has been made for any other
type of voltage supply and failure to use the supply provided could damage the
unit.
Note
It is not permissible to operate an HLA module on its own with a SIMODRIVE
monitoring module!
Power is supplied to downstream electrical axes via the DC link busbars (40
mm
2
) of the carrier module.
One position encoder for each axis can be evaluated on the HLA module.

The measuring system must always be plugged into the connector of the asso-
ciated axis.
