They have generic names.
• Replace the "n" character with the channel number, maintaining the brackets. The first
channel is identified with the number 1, "0" is not a valid number.
• Replace the "Xn" character by the name, logic number or index in the channel of the axis or
of the spindle.
• Replace the letters "i" and "x" with a number keeping the brackets.
These variables are read-only (R) synchronous and are evaluated during execution.
When parking an axis, it is a good idea to know which axes are available. Variables
(V.)[n].G.AXISNAME and (V.).G.GAXISNAME indicate which axes are available. If an axis is not
available, this variable returns the "?".
These variables are synchronous read/write (R/W). The variables correspond to linear and rotary
axes.
There are 2 software limits. The CNC applies the most restrictive one.
Variables POSLIMIT and NEGLIMIT correspond to the limits set by machine parameters. When
modifying these variables, the CNC assumes those values as the new limits from then on.
They keep their value after a Reset, but are reset when validating the machine parameters and when
turning the CNC on. Variables POSLIMIT and NEGLIMINT assume the values of the machine
parameters and RTPOSLIMIT and RTNEGLIMIT assume the maximum values.
These variables are read-only (R) synchronous and are evaluated during execution. These
variables correspond to linear and rotary axes.
It returns the resulting measurement of the active kinematics on that axis. It may be a particular value
of DATA (kinematics table) or the combination of several of them depending on the type of kinematics.
