根据报警说明查找程序，有的有N70，有的没有，但是找不到错误原因。
3006 Wrong block structure Acknowledgement key
When executing a part program

Machining stops

Interlocking of NC START

Approach to reference point with program and specification of the wrong G function or more than one axis, or
an impermissible axis.

Wrong thread lead parameters with G33

More than 3 M functions in the block

More than 1 S function in the block

More than 1 T function in the block

More than 1 H function in the block

More than 4 auxiliary functions in the block

More than 6 axes + geometry parameters

More than 5 axes with G00, G01, G02, G03

More than 2 axes with G10, G11, G12, G13, G110, G111, G112

More than one radius/angle with G10, G11, G12, G13, G110, G111, G112

Negative radius with G10, G11, G12, G13, G110, G111, G112

First programming of polar coordinates G10, G11, G12, G13 or angle/radius

More than two axes with G02, G03 (circle radius programming)

G04 programmed with addresses other than X, F or S

G04 is not programmed in the block by itself

M19 S is programmed with other functions

Incorrect circle parameters with G02, G03 axes

Axis missing with circle radius programming

Before the first G110 block in the program, a G10/G11 block must have been programmed

G110 may not be programmed with axes

Incorrect programming in connection with G176 freeze function

Either too few measured value memories or none at all have been defined for G720/721/722 via the flexible
memory configuration

On G511/G522
– An F word does not immediately follow G511/G522
– G511/G522 is superfluous, because neither a miscellaneous function nor a program coordination
command or an F word output to the PLC is programmed.

Check the faulty block in the “Correction block” display

If possible the cursor is positioned in front of the faulty word

The number of the faulty block is after the alarm number in the alarm line

Re G511/G522
– Place the F word immediately after G511/G522
– Delete G511/G522 F...
