M10 – Chuck Or Rotary Table Clamp closed

This command turns the Chuck Clamp output to LOW.

This is considered in MASSO logic as the Chuck Clamp being closed.


CAUTION: For safety, output LOW means the clamp is closed and an interlock signal from the spindle drive must be wired for safety so that the clamp does not open while the spindle/chuck is spinning.
