SINAMICS S120 HLA module components

HLA module
The HLA module is a DRIVE-CLiQ component and part of the SINAMICS S120 drive
system. The HLA module is designed for use in presses, rotary indexing machines and
forming and bending machines, for example.
The HLA module is used in conjunction with a SINUMERIK 840Dsl and a CU320-2 Control
Unit, CU-integrated or NX. Closed-loop control for the hydraulic axis (linear axis) is largely
performed by the Control Unit. From a topology viewpoint, the HLA module can be
considered to be a hydraulic double-axis Motor Module. From a functional viewpoint, the
HLA module is more like an option module or a Terminal Module.
Other SINAMICS components required
Additional SINAMICS components are required to provide the required functions:
● CU320-2 Control Unit, NCU-integrated or NX for processing drive and technology
functions
● 24 V power supply
This power supply is used to internally supply the SINAMICS S120 HLA and is also
required by the various sensors.
● 26.5 V power supply
This power supply is required for the hydraulic components (servo solenoid valves,
shutoff valves, pressure sensors, shutoff valve spool sensors) connected to the
SINAMICS S120 HLA.
The SINAMICS S120 HLA is solely intended for installation in a control cabinet.
In addition, the following are required:
● Sensor system connections to expand the functionality and provide various interfaces to
sensors.
