5.4 ”HLA module” control board
The hydraulics (HLA) module provides a means of controlling hydraulic axes
directly from the SINUMERIK 840D system via the digital drive bus.
The HLA module is a control unit belonging to the modular SIMODRIVE 611
converter system mounted in a 50 mm wide carrier module (universal empty
housing). The gating and closed–loop control electronics for operating hydraulic
drives are integrated in the HLA module.
The control unit can also be used as an ANA control unit for analog axes. This
double–axis board can be used in mixed operation (HLA/ANA).
Hydraulic drives have the same significance as electric drives also when com-
bined within an interpolating group.
Note
The HLA module is described in detail in:

HLA module, Description of Functions
The HLA module has the following features:
S Software and data
The communications interface is compatible with SIMODRIVE 611
SRM(FD)/ARM(MSD) for supported services. Code and data structure is
analogous to SIMODRIVE 611 SRM(FD)/ARM(MSD). The hydraulics soft-
ware is stored as a separate program code in the control system.
S Hardware
Integration into the SIMODRIVE 611 system is compatible with
SIMODRIVE 611 digital SRM(FD)/ARM(MSD). Essentially, this involves the
following interfaces:
– Drive bus
– Equipment bus
– Power supply concept
S HLA control unit (2–axis)
– Velocity pre–control, controller
– Force control
– Voltage output for actuators
– Connection for two pressure sensors per axis
– Control of hydraulic control valves
S Terminals and diagnostics
– Control of a hydraulic shut–off valve
– BERO input per axis
– Module–specific enable signal
– Test sockets (diagnostics)
