Bit 0 - 4 Axis number for handwheel 1, 2 or 3
Edge evaluation: no
Significance of signal The operator can assign an axis to every handwheel directly via the operator panel front. To do so,
he defines the required axis (e.g. X). The basic PLC program provides the number of the axis plus
the information "machine axis or geometry axis" (IS "machine axis") as HMI interface signals. The
basic PLC program sets the interface signal "Activate handwheel" for the defined axis. Depending
on the setting in the HMI interface signal "machine axis", either the interface for the geometry axis
or for the machine axis is used.
The following must be noted when assigning the axis designation to the axis number:
NST "machine axis" = 1; e.g. machine axis:
The assignment is done via the machine data:
MD10000 $MN_AXCONF_MACHAX_NAME_TAB[n] (machine axis name).
NST "machine axis" = 0; e.g. geometry axis:
The assignment is done via the machine data:
MD20060 $MC_AXCONF_GEOAX_NAME_TAB[n] (geometry axis name in channel)
With the NST "Channel number geometry axis handwheel n" the channel number assigned to the
handwheel is defined.
For following codes are used for the axis number:
Corresponding to .... DB10 DBX97 ff (Channel number geometry axis handwheel n)
DB10 DBX100.6 ff (handwheel selected)
DB10 DBX100.7 ff (machine axis)
DB21, ... DBX12.0 to DBX12.2 ff (activate handwheel)
DB31, ... DBX4.0 to DBX4.2 (activate handwheel)
MD10000 $MN_AXCONF_MACHAX_NAME_TAB [n] (machine axis name)
MD20060 $MC_AXCONF_GEOAX_NAME_TAB [n] (geometry axis in the channel)
