The position of the Gantry axis is displayed next to its associated axis unless machine parameter
"DFORMAT(P1)=3".
SYNCHRO (P3)
Not being used.
DROAXIS (P4)
Indicates whether it is a normal axis or it only works as a Digital Read Out
LIMIT+ (P5) LIMIT - (P6)
They set the travel limits for the axis (positive and negative). Each one of them indicates the distance
from machine reference zero to the relevant travel limit.
On linear axes, if both parameters are set to 0, the travel limits will be ignored.
On the rotary axes, act as follows:
• When both parameters are set to "0", the axis may be moved indefinitely in any direction (rotary
tables, indexers, etc.)
• When working with positioning axes and Hirth axes, try to program in incremental coordinates
to avoid mistakes. For example, C axis with P5=0, P6=720 and the positioning axis in 700 (340
on the screen), when programming G90 C10, the CNC tries to move the axis via the shortest
path (701, 702, etc.) but it will issue an error message for overrunning the travel limits.
• If the travel of positioning axes and hirth axes is limited to less than a turn, they cannot move
via the shortest path.
• When the travel is limited to less than a revolution and a positive and negative display is desired,
for example P5=-120, P6=120, it is possible to program G90 with positive and negative values.
Example:
If the X and U axes form a Gantry pair, the U axis being the slave axis, program as follows:
Parameter GANTRY (P2) for the X axis = 0
Parameter GANTRY (P2) for U axis = 1 (associated with X axis)
This way, When programming an X axis move, the U axis will also move the same distance.
Value Meaning
NO It is a normal axis.
YES It only works as a Digital Read Out.
Default value: NO
Possible values

Default value: For LIMIT+ (P5) = 8000 mm.
For LIMIT- (P6) = -8000 mm.
