User-specific keys
The user-specific keys can be freely assigned. You can label the keys with your own texts in the
local language.
Integrated machine control panel
The HT 10 has an integrated MCP. It comprises mechanical keys (e.g. start and stop) as well as
keys emulated as softkeys.
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 10 has an acknowledgment button. You can then activate the acknowledgment function
for operator actions that require approval (e.g. displaying traversing keys).
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 using the mechanical 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.
Note
You can also traverse your machine axes using touch operation.
