Hello everyone, I have a problem when I used the CNC interpolator to move the A/B/C axis of 6DOF robot.

When I set the A/B/C axis(SMC_NCInterpreter.eOriConv:= SMC_ORI_CONVENTION.ZYX) in G-code, the SMC_Interpolator.piSetPosition return me a large dA and dC, what's happened in the SMC_Interpolator FB?

My G-code as follow:
N000 G01 X420 Y0 Z445 A180 B180 C180 F1000
N005 G02 X420 Y167 Z445 I-25 J80
N010 G01 X500 Y0 Z445 A135 B180 C180
N015 G02 X500 Y0 Z445 I100 J0
N025 G03 X500 Y-155 Z445 I-30 J-80
N030 G91
N035 G01 Z50
N040 G90 F50
N040 G01 X420 Y0 Z500

And I have catched the picture of piSetPosition dA/dC value in the attachments named "Set ABC.jpg". The dA/dC up to 5000deg.

If I just set the A/B/C in G00, the robot seems to be worked well.
N000 G00 X420 Y0 Z445 A180 B180 C180 F1000
N005 G02 X420 Y167 Z445 I-25 J80
N010 G01 X500 Y0 Z445
N015 G02 X500 Y0 Z445 I100 J0
N025 G03 X500 Y-155 Z445 I-30 J-80
N030 G91
N035 G01 Z50
N040 G90 F50
N040 G01 X420 Y0 Z500

but the SMC_Interpolator.piSetPosition still return me a large dA and dC, I have catched the picture in Attachments named "do not set ABC in G01.jpg"

Thanks for any answers and suggestions.
