functions
Explanation On the first level the file functions refer to all the machine data areas (Drives, NC,
PLC, Cycles, IKA). The data selector always displays the relevent files (TEA3,
TEA1, TEA2, TEA4, IKA1, IKA2, IKA3).
Notes When saving the cycles MD (TEA4), always make sure that the TEA4 file can
consist internally of up to 7 files. This is because the channel-dependent cycles
MD are saved in one file per channel, the central MD are stored in another file.
The channel number is added to the file name, i.e. the name of the file to be sto-
red is limited to 7 letters on the first level.
The steps required to load the files containing the drive data, “Accept config. +
NCKP0” and “Accept all + NCKP0”, are executed automatically. Such a file must
therefore always contain a complete drive file (configuration + drive).
When the drive files are being loaded the display jumps back to the basic display
(JOG) after the configuration has been automatically saved and NCK Power On.
The message “Start-up necessary – Power On” appears. The drive data are then
loaded and NCK – Power On is repeated. The message “Start-up necessary –
Power On” disappears.
When loading files on the first level, the message “Start-up necessary – Power
On” must not be acknowledged with “Power On” (switch on/switch off).
An NCK Reset must be executed when TEA3 data are loaded (drive machine
data) even if no drive exists.

Saving and loading NQEC data

The MDD functions “Save all” and “Load all” have been expanded to include the
NQEC data.
