Axis-specific variables (V.A.)
The code for axis-specific variables is "V.A. ...". It can be specified in 2 variants:
1: Axis name according to channel list (represented with “X” as example below)
2: Axis index [i] according to channel list where <i>: 0…31
Example: V.A.ABS.X or V.A.ABS[0]
Attention
V.A. variables can only be programmed for linear and rotary axes but not for spindles.
Notice
Read access to the variables with the identifier LFlush causes flushing of the NC channel.
For example, flushing the NC channel can result in the error ID 20651 if tool radius compensation (G41/G42) is active.

Release Note
