Hydraulic Linear Actor (HLA module)
■
Overview
Hydraulic Linear Actor (HLA module)
The 2-axis HLA module is a DRIVE-CLiQ component for control
cabinet installation.
•
From a topology viewpoint, the HLA module can be viewed as
a hydraulic double-axis Motor Module. The HLA module is an
interface module for the I/O components of a hydraulic linear
drive.
•
The HLA module therefore functions in a similar way to a
Terminal Module. This module can be used for a variety of
different purposes in the SINAMICS S120 drive line-up.

Function
The HLA module has been designed to control (open-loop and
closed-loop) electro-hydraulic control valves of hydraulic linear
axes in conjunction with the SINUMERIK 840D sl. Up to two
hydraulic axes can be controlled by this module.
To control a hydraulic linear drive, a control unit is required
in addition to the HLA module. This unit can be either the
NCU 7x0.3B PN, an NX or a CU320-2 Control Unit which
operates under the control of a SINUMERIK 840D sl system.
By combining a control unit with the HLA module, it is possible
to create a highly dynamic, electro-hydraulic control circuit.
A hydraulic linear axis can be combined and interpolated with
other hydraulic or electrical axes on one SINUMERIK 840D sl.
The HLA module requires a 24 V supply. This power supply is
used to internally supply the HLA module and is also required by
various sensors.
The HLA module generates the power supply for the control
valves and the shutoff valves from an external DC voltage supply
(e.g. SITOP) with a rated voltage of 26.5 V.
The purely hydraulic components, designed for CNC operation,
must be supplied by the user.
