M11 – Chuck Or Rotary Table Clamp Open

This command sets the Chuck Clamp output to HIGH.

 

In MASSO logic, this means the Chuck Clamp is open.

 


CAUTION: For safety, output HIGH means the clamp is open. An interlock signal from the spindle drive must be wired so the clamp cannot open while the chuck is rotating.
