M26, M27 (Rotary axis clamping)

the a axis is often used to rotate the workpiece on the machine and then do milling on that side of the workpiece to be sure the workpiece is fixed in its place an axis clamp (brake) can be used for a m26 q p where the q parameter specifies the axis and the p parameter specifies an aux output that will enable the clamp and the optional p1 specifies the output that controls the brake, e g m26 qa p1 , qa specifies axis a, p1 specifies aux1 m27 q disables the clamp on the axis specified by the q parameter, e g m27 qc disables the clamp for axis c when m26 is active, the software does not accept motion such as from g code and jogging, an error message will appear that the axis is clamped
