ESC (Global Abort)
Terminate any active operation and cause the controller to revert to the idle state waiting for a new
command. Output drivers or ports are NOT affected. Stepping and position counter update will cease
immediately without deceleration. The lack of deceleration can cause mechanical overshoot. The controller
will echo a “#” character. This command may not be used within the non-volatile program memory.

program without causing termination.
