CNC VARIABLES.
(REF: 1402)
Variables related to the programmed functions.
(V.)[ch].A.ACCUDIST.xn
(V.)[ch].A.ACCUDIST.sn
(V.)[ch].SP.ACCUDIST.sn
Variable that can be read and written via program, PLC and interface.
Variable valid for rotary and linear axes as well as for spindles.
The variable returns the execution value; reading it interrupts block preparation.
Distance traveled by the axis or spindle since the last coordinate latching. This variable is
initialized to ·0· when a latching event takes place. To add a position offset to this variable
at the latch point, just add it from the PLC in a later cycle.
Axis synchronization pemits treating a rotary axis as an infinite axis making it possible to
increase the feedback count of the axis indefinitely (wihout limits) regardless of the value of
the module. The CNC uses this variable follow up on the axis. This variable may be initialized
in a sampling period and keep counting from the initialized value on.
This feature is useful, for example, for a rotary axis or encoder that moves an endless coveyor
belt on where the part is. The infinite axis treatment allows synchronizing the coordinate of
the conveyor belt with an external event and, this way, count the moving distance of the part
beyond the value of the module of the rotary axis that moves the belt.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
·sn· Name, logic number or index of the spindle.
(V.)[ch].A.PREVACCUDIST.xn
(V.)[ch].A.PREVACCUDIST.sn
(V.)[ch].SP.PREVACCUDIST.sn
Variable that can be read and written via program, PLC and interface.
Variable valid for rotary and linear axes as well as for spindles.
The variable returns the execution value; reading it interrupts block preparation.
Distance traveled by the axis or spindle between the last two coordinate latchings. This
variable updates (refreshes) its value at every latching event; that's why the variable will have
a ·0· value until the first one takes place.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
·sn· Name, logic number or index of the spindle.
