Customer keys
The four customer keys can be assigned arbitrarily and can be configured customer-
specifically.
Integrated machine control panel
An MCP is integrated in the HT 8. It is comprised of keys (e.g. start and stop) as well as softkeys
emulating keys.
A description of individual keys can be obtained in the chapter "Controls on the machine control
panel".
Note
PLC interface signals that are triggered via the softkeys of the machine control panel menus are
edge triggered.
Acknowledgment button
The HT 8 has two acknowledgment buttons. You are therefore provided the opportunity of
activating the acknowledgement function for operator actions which require approval (e.g.
showing the traversing keys) with either hand.
Acknowledgment buttons are available for the following button positions:
● Released (no activation)
● Acknowledgment (center position) - acknowledgment for channels 1 and 2 is on the same
switch
● Panic (completely pushed through)
Traversing keys
To traverse the axes of your machine with the HT 8 traversing keys, "JOG" or "MDI" mode and
the "REF. POINT" or "TEACH IN" functions must have been selected. You have to press the
acknowledgment button depending on the setting.
Virtual keyboard
A virtual keyboard is available for the easy entry of values.
