11.6.4.10 G51 (Round path transition)
Function: To change the transition mode into arc transition. The following transition modes are always
arc transition. G50/G52 can be used for the switch of transition modes in the execution process. The
terminal actuator will not reduce its speed between G codes and the transition curve is an arc. In this
mode, the speed of the first G code prevails as the entire motion speed and F can not be used for
changing the speed in the motion. VelOverride parameter of DMC_CartesianCoordinate instruction
can be set to control the speed of terminal actuator.
Format: N_ G51 D_
Parameter Explanation:
N_:The row number of G code in NC program
D_:Radius of the arc
