19.11.2 Function call
FC15
PLC function call FC15 can be used to start concurrent positioning axes from the PLC.
The following parameters are passed to the function call:
● Axis name/axis number
● End position
● Feedrate (with feedrate setting = 0, the feedrate is determined by the setting in the
● Absolute coordinates (G90), incremental coordinates (G91), absolute coordinates along
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.
