P2: Positioning axes
10.5 Programming
Extended Functions
620 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
Tool offset
A tool length compensation for positioning axes can be implemented by means of an axial
zero offset, allowing, for example, the positioning path of a loader to be altered. An example
where the axial zero offset might be used in place of the tool length compensation is where a
loader containing tools of various dimensions has to bypass an obstacle.
End of program
The program end (program status selected) is delayed until all axes (path axes + positioning
axes) have reached their programmed end points.
10.5.2 Revolutional feed rate in external programming
The two following setting data can be used to specify that the revolutional feed rate of a
positioning axis should be derived from another rotary axis/spindle:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE(revolutional feed rate for position
axes/spindles)
SD42600 JOG_FEED_PER_REV_SOURCE (control of revolutional feed rate in JOG)
The following settings are possible:
Value Description
0 No revolutional feed rate selected
>0 The revolutional feed rate is derived from the round axis/spindle with the machine axis
index specified here.
-1 The revolutional feed rate is derived from the master spindle of the channel in which the
axis/spindle is active.
-2 The revolutional feed rate is derived from the rotary axis/spindle with the machine axis
index 0.
-3 The revolutional feed rate is derived from the master spindle of the channel in which the
axis/spindle is active. No revolutional feed rate is selected if the master spindle is at a
standstill.
