MD info window
(SW 3 and higher)
Select the MD info window function with the “End” hardkey.
Fig. 5.2
Explanation With the “End” hardkey you can call up an info window for any machine data on
which the cursor is placed (not in Machine configuration). Minimum and
maximum values, the internal representation, any relationships with other
machine data and any inputs if they exist (e.g. yes/no) are displayed next to the
text and number.
In SW 4 and higher, an optional fixed text can be assigned to any individual ma-
chine data, viewed and values entered or toggled.
In SW 4 it is also possible to select transformation blocks and configurations.
Increment/decrement The values of certain machine data can be altered either in percent or by
function predefined values using the hardkeys + (increment) and – (decrement). Operate
(SW 3 and higher) the End hardkey to find out which changes can be made. Under possible inputs
you will find the next value in the + and – direction.
“+/–” function
(SW 3 and higher)
You can select the available (configured) drives, axes, spindles, channels and
numbers (e.g. IKA) using the +/– function.
Calculating controller data (SW 4 and higher)
Press this softkey to select the function Calculate controller data.
As from SW 4, it is possible to load the standard data from the hard disk for
motor selection (previously: data for MSD from EPROM). When the standard
data have been loaded some of the controller data are automatically calculated
and set in the drive. If a motor from a different manufacturer is used no guarantee
can be made that this procedure will be carried out. First, the specific motor data
must be entered manually and then the following controller data must be
calculated and set by pressing the Calculate controller data softkey:
