SINUMERIK 840D/840Di/810D Operator's Guide HMI Advanced (BAD) – 03.04 Edition
A set of instructions grouped under one identifier. In the program, the
identifier represents the set of grouped instructions.
A block prefixed by ":" containing all the parameters required to start
execution of a -> parts program.
-> Parts program identified by a number or name in which other main
programs, subroutines or -> cycles may be called.
Control system operating mode: Manual Data Automatic. In the MDA
mode, individual program blocks or block sequences with no
reference to a main program or subroutine can be input and executed
immediately afterwards through actuation of the NC Start key.
· SINUMERIK FM-NC: The requisite control circuits for axes and
spindles are integrated in the control module as standard. A
maximum total of 4 axes and spindles can be implemented, with
no more than 2 spindles.
· SINUMERIK 840D: The signals from the sensors are analyzed in
the SIMODRIVE 611D drive modules. The maximum configuration
is a total of 8 axes and spindles, with up to 5 spindles being
permissible.
All messages programmed in the parts program and -> alarms
detected by the system are displayed in plain text with date and time
and the corresponding symbol for the delete criterion on the operator
panel. Alarms and messages are displayed separately.
Standardized system of units for lengths in millimeters (mm), meters
(m), etc.
Mirroring exchanges the leading signs of the coordinate values of a
contour in relation to an axis. Analogously, several axes can be
mirrored simultaneously.
An operating concept on a SINUMERIK control. The modes -> Jog, ->
MDA, -> Automatic are defined.
All axes/spindles are assigned to one and only one channel at any
given time. Each channel is assigned to a mode group
The same -> mode is always assigned to the channels of a mode
group.
