Axis movement by
interpolator
If the interpolator wants to move the axes, the markers
NN_AxMotionRequest or NN_SpiMotionRequest are set. The PLC then
switches on the drive, activates the control loop, releases the brake, and
enables the feed rate or spindle.
If a spindle is moved by the NC and not by the PLC program, the
NN_SpiMotionRequest marker is set. This allows the PLC program to decide
when the spindle drive is to be switched on.
