SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
The NCU 573.2 of the SINUMERIK 840D is capable of handling axis configura-
tions of a maximum of 31 axes on 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 con-
trolling 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
SIMODRIVE 611 converter system mounted in a 50 mm carrier module
(universal empty housing).
The gating and closed-loop control electronics for operating controlled 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
electric and hydraulic drives as equal partners and integrating them into a stan-
dard NC.
To place equal emphasis on the functional importance of both hydraulic and
electric drives and make them available as a combined system within an inter-
polating axis grouping.
S
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
