SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
The NCU 573.2 of the SINUMERIK 840D is capable of handling axis
configurations of a maximum of 31 axes in up to 10 different channels. This
functional sophistication makes the SINUMERIK 840D an increasingly popular
system for the automation of rotary indexing machines. These machines are
often highly compact in design and frequently equipped with hydraulic axes
(cylinders and servo solenoid valves). 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 closed-loop control plug-in unit of the modular SIMO-
DRIVE 611 converter system mounted in a 50 mm carrier module (universal
empty housing).
The gating and closed-loop control electronics for operating hydraulic drives are
integrated on the HLA module.
From the point of view of the manufacturer of modern servo solenoid valves, an
innovative step in the field of hydraulic drive systems has been taken by treating
electrical and hydraulic drives as "equal partners" and integrating them into a
standard NC.
To place equal emphasis on the functional importance of both hydraulic and
electrical drives and make them available as a combined system within an inter-
polating axis grouping.

Firmware
The communications interface is compatible with the SIMODRIVE 611D
SRM(FDD)/ARM(MSD) for supported services. Code and data management
is analogous to the SIMODRIVE 611D SRM(FDD)/ARM(MSD). The hydrau-
lics software is stored as a separate program code in the control system.
S
Hardware
The mode of integration into the SIMODRIVE 611 system is compatible with
the SIMODRIVE 611 digital SRM(FDD)/ARM(MSD). This basically involves
the following interfaces:
– Drive bus
– Device bus
– Power supply system
