Note
Direction key LEDs are controlled by operating the direction keys.
Axis selection and WCS/MCS LEDs are controlled by operating the relevant pushbutton switch.
Call example
CALL FC19(
BAGNo :=
ChanNo :=
SpindleIFNo :=
FeedHold :=
SpindleHold :=
With these parameter settings, the signals are sent to the first mode group, the first channel
and all axes. In addition, the spindle override is transferred in the 4th axis/spindle interface.
The feed hold signal is passed to bit memory 22.0 and the spindle stop signal to data block
DB2, data bit 151.0.
Reconnecting the axis selections
To ensure a flexible assignment of the axis selection keys to the appropriate axis or spindle,
FC19 needs not be modified or reprogrammed. The axis number simply has to be entered in
axis table DB10.DBB8 and followed as required: The axis number simply has to be entered in
axis table DB10.DBB8 and followed as required:
Example
The spindle is defined as the 4th machine axis and must be selected via axis key 9.
Solution:
The value 4 must be entered in DB10 byte (8+(9-1)) for the 4th axis.
