No traversing key signals to machine axes with active WCS.
The FC 26 function can be used to lock the transfer of the traversing key signals to the
machine axis with active WCS (AB n + 0, Bit 0 = 1). This functionality is to be activated by
the user (machine manufacturer) in the PLC user program by setting the following output
signals:
●
AB n + 3, Bit 7 (in WCS: no machine axes)
● AB n + 2, Bit 6 (Axes 7 - n selected)

The traversing key signals for Axes 1 - 3 of the machine axis table are output to the
geometry axes of the channel specified via the "ChanNo" parameter.
The traversing key signals for Axes 4 - 6 of the machine axis table are output to the
corresponding axis-specific interfaces.

7.6.5.5 Display traversing keys
To display the traversing keys on HT 8, the following output signal must be set in the PLC
user program:
●
AB n + 6, Bit 7 = 1 (display traversing keys)
Checkback signal from HT 8
HT 8 sets the following input signal as checkback signal that the traversing keys have been
displayed on HT 8:
●
DB 10, DBX 72.7 = 1 (Traversing keys displayed)
Inscription of the traversing keys
On displaying the traversing keys, the machine axis names or the traversing key identifiers of
the machine axes recorded in the table (DB 10, DBB 8 - 13) are used as inscriptions. In this
context, the machine axis numbers entered in the table serve as indices in the following
tables:
●
HMI file: HT8_xx.INI, Section [Axiskey Text] (Table of traversing key identifiers)
● MD 10000, $MC_AXCONF_MACHAX_NAME_TAB[n] (Table of machine axis names)
