Circle Interpolation Problem

[Leigh @ Kodiak]

I am experiencing a strange issue here. The machine is new to us, a Doosan DNM6700 with rotary table. When trying to do a G03 move,  I get the alarm "PS0020, "OVER TOLERANCE OF RADIUS". i understand what this alarm means, and to my eye, the code checks out fine.

 

In the process of trying to figure out what is causing the problem, I switched Parameter 3410 (Tolerance of Arc Radius). to .250 (initially it was .0039) then when ruining the code, during the G03 moves, I get no alarm, but the A axis is moving along with X & Y during the G03 move, despite no A move being commanded.  What is going on here?!?

 

Here is the code that is causing the problem:

N110 G91 G28 Z0.
N120 (ROUGH BORES A180)
N130 (COMPENSATION TYPE - WEAR COMP)
N140 T9 M06 (3/8 4FL ENDMILL)
N150 (MAX - Z4.)
N160 (MIN - Z1.5)
N170 M11 (UNLOCK)
N180 G00 G17 G90 G54.1 P48 A180.
N190 M10 (LOCK)
N200 S4700 M03
N210 X24.0117 Y-1.9844
N220 G43 H9 Z4. M07
N230 Z2.05
N240 G94 G01 Z1.8333 F25.
N250 G41 D9 X23.9925 Y-1.9614 F13.2
N260 G03 X23.8865 Y-2. I-.046 J-.0386
N270 X23.8865 Y-2. I.1135 J0.
N280 G01 X23.8866 Y-2.005
N290 G03 X23.9942 Y-2.0389 I.06 J.0026
N300 G01 G40 X24.0124 Y-2.0151
N310 G00 Z4.

Do you have positive comp in the tool in the control?

Comp is set to 0.000

That A is not only not commanded, it should be locked......

I'd be concerned about something being wired wrong. or a drive card going bad..I'm thinking that A motion could be ultimately causing the issue..

I might pull everything off the machine and do some testing on code before moving forawrd
