AXISSTATUS = L Speed limit active - how to deal with it?

AXISSTATUS = L Speed limit active - how to deal with it?

AXISSTATUS L flag means the axis is in speed limited mode.  It means it's running a MOVESP/MOVEABSPS/MOVECISRCSP and the VP_SPEED is not the SPEED but is at the FORCE_SPEED level.  

If CORNER_MODE is active, that will also show as speed limiting with the L.

It can't be cleared, it's only for information.

      The max speed of the axis might be acceleration limited. For example: SPEED = 800 ACCEL = 1200 DECEL = 1200 Say the vector length = 600 - 500 = 100. ie the MOVE length is 100. From the standard equation of motion: v^2 = u^2 + 2as u is 0 v = SQR(2 * ...
