18.10.2 Function call - only 840D sl
FC18
For SINUMERIK 840D sl, concurrent positioning axes can be started from the PLC using
FC18 (Function Call 18) of the PLC. The following parameters are passed to the function
call:
● Axis name/axis number
● End position
● Feedrate
(for feedrate = 0, the feedrate is taken from MD32060 $MA_POS_AX_VELO)
The F value of FC18 is nottransferred to the axis-specific IS DB31, ...DBB78-81 ("F
function (feedrate) for positioning axis")
● Absolute coordinates (G90), incremental coordinates (G91), absolute coordinates along
the shortest path for rotary axes (rotary axis name = DC(value))
Since each axis is assigned to exactly one channel, the control can select the correct
channel from the axis name/axis number and start the concurrent positioning axis on this
channel.
