Advanced System Variables
The following system variables are only used in conjunction with advanced 5X machines. They are also available throughout the post process, and are not specific to any given block.
|
System Variable |
Default format |
Use and Comments |
|
VIRTUAL_ANGLE_1 VIRTUAL_ANGLE_2 VIRTUAL_ANGLE_3 |
2 |
These angles are calculated by the CALC_VIRTUAL_ANGLES statement when virtual axis rotations are used on the machine to define work planes. The rotation method (Euler or Spatial), the axes used and the order of rotations are all defined by the VIRTUAL_AXES variable. |
|
I_WORKPLANE J_WORKPLANE K_WORKPLANE |
18 |
The Z orientation vector of the work plane rotation matrix (calculated by the CALC_WORKPLANE statement). |
|
IX_WORKPLANE JX_WORKPLANE KX_WORKPLANE |
18 |
The X orientation vector of the work plane rotation matrix (calculated by the CALC_WORKPLANE statement). |
|
X_OUTPUT_UCS Y_OUTPUT_UCS Z_OUTPUT_UCS |
1 |
These variables describe the current origin of the output UCS, relative to the REF UCS. By default, they are set to (0,0,0), and can be modified with the SET_OUTPUT_UCS statement. |
|
I_OUTPUT_UCS J_OUTPUT_UCS K_OUTPUT_UCS |
18 |
These variables describe the current output UCS Z orientation vector, relative to the REF UCS. By default, they are set to (0,0,1), and can be modified with the SET_OUTPUT_UCS statement. |
|
IX_OUTPUT_UCS JX_OUTPUT_UCS KX_OUTPUT_UCS |
18 |
These variables describe the current output UCS X orientation vector, relative to the REF UCS. By default, they are set to (1,0,0), and can be modified with the SET_OUTPUT_UCS statement. |
|
X_NONROT_UCS Y_NONROT_UCS Z_NONROT_UCS |
1 |
These variables are the same as the output UCS origin relative to the REF UCS, but without considering any table rotation. They are set each time the SET_OUTPUT_UCS statement is used. |
|
I_NONROT_UCS J_NONROT_UCS K_NONROT_UCS |
18 |
These variables are the same as the output UCS Z axis relative to the REF UCS, but without considering any table rotation. They are set each time the SET_OUTPUT_UCS statement is used. |
|
IX_NONROT_UCS JX_NONROT_UCS KX_NONROT_UCS |
18 |
These variables are the same as the output UCS X axis relative to the REF UCS, but without considering any table rotation. They are set each time the SET_OUTPUT_UCS statement is used. |
|
CON_AFTR_RECONFIG |
6 |
Set to TRUE_ if this connection takes place immediately after a machine reconfiguration process. It is FALSE_ in all other cases. |
|
INACCURATE_ORIENT |
6 |
This flag is set by GPP2 to TRUE_ if the tool orientation is inaccurate because the machine contains one or two indexed (non-continuous) axes, and the required tool orientation cannot be achieved. It is set during the BEGINNING OF CONNECT block if the connection point orientation is inaccurate, and in all motion blocks (For example, LINEAR MOTION). It is always FALSE_ in machines without indexed axes. |
|
INACCURATE_ERROR |
2 |
This variable is meaningful only if the INACCURATE_ORIENT flag is set to TRUE_. It indicates the size of the orientation vector error, in angles (the difference between the required and the resulting tool orientation). |
