Z axis moving in a block that does not call it?

Verifun · 2013-09-22 23:20:50

I'm working in a Sinumerik control and I'm getting a very weird behavior with blocks calling several axes in the same block...

Notice the block below: We don't have a Z axis being called there...

G0 SUPA X= 700 Y= 0 B= -90 SPOS= 0

However, when Z axis is at a location other than 1500, which is the Z axis initial machine location as shown below, when I execute the block above (present within the control sub-routine file), the machine moves itself to a Z1 position of 1500mm... there's not such statement in the block above... - Z should stay where it is prior the block execution...

Any ideas about what's wrong in my control file?

By the way: below my axis priority list:

could it be that RTCP or RPCP is active?
could it be that the SUPA command causes a change in RotationPlane macro?
Both settings might cause movement of unspecified axis.

I'll look into that Patrick!

Tks!

Perhaps you had an workoffset update in this sequence, following the logic of your control.

After you update the work offset, try to update the axis values using "UpdateAxisValues" macro.

Thanks Marcos!

I'l try this too...
