C Axis Lock

We have added a "CAXIS_Lock" variable to M53. And a matching error macro under the "C *" register.

This gives an error on every C value in the NC code when the axis is locked. Even if it's not moving. How do I get it to give an error only when the C value is different to the C value when it was locked?

ie- 

C0
M53 (LOCK C AXIS)
C0       --> no error wanted.

C0
M53 (LOCK C AXIS)
C10.    --> error needed.

Cheers.

Re: C Axis Lock

Hi,

You have to track the actual axes values in Advanced Control Options=>Events=>Start of Processing by adding a macro SetDynamicVars with the text AxisLocalPlus 0000000 $AA_IW[X] $AA_IW[Y] $AA_IW[Z] $AA_IW[A] $AA_IW[B] $AA_IW[C] $AA_IW[U] $AA_IW[V] $AA_IW[W].

See any of the Siemens 840D sample files. You can give the variables other names.
Then just put a condition under C in word adress, when M53=1 and $AA_IW[C] not equal the input C value, that gives an error message.
