What does G7.1 mean?

[sinha_nsit]

As per manual, it is "start lock signal" (STLK). What does it mean?
Thanks.

What controller is it? I don't think it is present in all controls.
It looks like it would be the G7.1 register bit transfered to the CNC by the PMC, if used, to lock out a Cycle Start?
Similar to MLK, Machine Lock, which locks the axis.

It is 0i Mate TC.
I believe, this signal will disable CYCLE START button.
Am I correct?

That would be my guess, I don't remember it in the older controllers?

G07.1 IP r ; Starts the cylindrical interpolation mode (enables cylindrical interpolation).
G07.1 IP 0 ; The cylindrical interpolation mode is cancelled.

IP : An address for the rotation axis
r : The radius of the cylinder
Specify G07.1 IP r ; and G07.1 IP 0; in separate blocks. G107 can be used instead of G07.1

It is just that the STLK looks like a BMC register label for the ladder?

I remember that the STLK signal was used on the old 5T and 6T lathe controls. It was called "start lock", but it does do more than just prevent the cycle start event. As I recall, it also prevented all axis motion. It was mostly used to sense a tool turret that was not locked down. The older Mori Seikis had this signal wired to a switch under the turret so that the machine could not move while the turret was indexing. Unlike the OT or E-stop signals, the STLK signal is effective when it goes "high" to +24vdc. The mill controls (5M and 6M) had idividual interlock signals for each axis (ITX, ITY, and ITZ) rather than a single STLK signal.
