SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Note
Each of the shutoff valves must be connected directly via 2 leads to pins 2/3 of
X431 or X432!
A current-compensated interference suppression coil is inserted at the input for
the external incoming supply terminal P24, terminal M24 (pins 5 and 6 of
X431).
Terminal M24 and terminal MV1/MV2 must therefore not be reversed or short-
circuited.
The internal enabling voltage (terminal 9) is provided for the supply of BEROs
and terminal 663 and must not be used to supply hydraulics components. The
hydraulics components must be supplied via incoming supply P24. The volt-
ages may not be connected in parallel.
Module-specific enabling commands are issued by terminal 663. As no power
section is installed, no relay is available. The input is therefore evaluated via
optocouplers in the HLA module and applied additionally to the shutoff valves.
The enable voltage can be picked off at terminal 9.
Terminal 663 is referred to the internal enabling voltage (ground, terminal 19).
Using the Start-Up Tool or an MMC102/103, it is possible to assign internal sig-
nals to the test sockets on the 611D drive (in conjunction with SINUMERIK
840D), where the signals are then available as analog values (see also Section
3.11).
DAC1 DAC2
DAC3 Ground
Three 8-bit digital/analog converter (DAC) channels are available on the 611D
hydraulics module. An analog image of various drive signals can be connected
through to a test socket via these converters.
Only a window of the 24-bit wide drive signals can be displayed with the 8 bits
(=1 byte) of the DAC, see Fig. 5-3. For this reason, the shift factor must be set
to determine how fine the quantization of the selected signal must be. The nor-
malization factor is calculated as the parameters are set and displayed as user
info, e.g. 1V = 22.5A.
