Test Sockets (Diagnostics) - Siemens 6SN1123-1AA00-0DA2 Configuration Manual

05.01
Notice
Each of the shut–off valves must be connected directly using two conductors
connected 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 may therefore not be reversed or
short–circuited.
The internal enable voltage (FRP/9) is provided in order to supply the BEROs,
and terminals 663 may not be used to supply the hydraulics components. The
hydraulic components must be supplied via incoming supply P24. The voltages
may not be connected in parallel.
Input enable
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 taken from terminal 9.
Terminal 663 is referenced to the internal enable voltage (ground, terminal 19).

Test sockets (diagnostics)

Measuring sockets
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.
Functionality
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. For this reason, the shift factor must be set to determine
how fine the quantization of the selected signal must be. The normalization fac-
tor is determined when parameterizing and displayed to the user.
