Notice
There is a current–compensated radio interference suppression reactor at the
input of the external supply, terminal P24, terminal M24 (Pins 5, 6 of X431).
This is the reason that it is neither permissible to interchange nor short–circuit
terminal M24 and terminal MV1/MV2.
The internal enable voltage (FRP/9) is provided to supply the BEROs and
terminal 663, and may not be used to supply the hydraulic components. The
hydraulic components should be supplied via the supply, P24. The voltages
may not be switched in parallel.
The module–specific enable is realized via terminal 663. There is no relay as
there is no power module; the input is evaluated via opto–coupler and additio-
nally acts on the shut–off valve.
Terminal 663 is referred to the internal enable voltage (ground, terminal 19).

Test sockets (diagnostics)

Internal signals can be assigned to test sockets of the 611D drive (in conjunc-
tion with SINUMERIK 840D) using the start–up tool or the MMC102/103. These
signals are then available at the test sockets as analog values.
DAU1
DAU3
8–bit D/A converters (DAU) channels are available at the 611D hydraulic
module. An analog image of various drive signals can be switched to a test
socket via these channels.
Using the 8 bits (=1 byte) of the DAU, only a specific window of the 24 bit drive
signals can be displayed. For this reason, the quantization of the selected si-
gnal must be defined using a shift factor. The normalization factor is determined
when parameterizing the system and is displayed to the user.
