Note
Each of the shut-off 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 in order to supply the
BEROs and terminal 663, and must not be used to supply hydraulics
components. The hydraulics components must be supplied via incoming
supply P24. The voltages 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 also acts on the shut-off valves.
The enable voltage can be picked off at terminal 9.
Terminal 663 is referenced to the internal enabling voltage (ground, termi-
nal 19).
The start-up tool or an MMC102/103 can be used to assign internal signals 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.
