• 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 total
configuration is 8 axes and spindles, with no more than 5
spindles.
All messages programmed in the part program and --> alarms
detected by the system are displayed in plain text 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. Mirroring can be performed
simultaneously in relation to several axes.
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.
This function can be used to initiate actions that are synchronized
with the machining operation. The starting point of the actions is
defined by a condition (e.g. status of a PLC input, time elapsed
since beginning of a block). The start of motion--synchronous
actions is not tied to block boundaries. Examples of typical
motion--synchronous actions are:
Transfer M and H auxiliary functions to the PLC or deletion of
distance--to--go for specific axes.
