= 0 With direction selection + or -, both calculated solutions for the rotary axes are approached
= 1 With direction selection + or -, only one of the calculated solutions for the rotary axes is
approached
Traverse the zero offset for the rotary axes of the swivel data set as offset
= 0 Only take the zero offset for the rotary axes of the swivel data set into account in the WCS
(compatibility)
= 1 Traverse the zero offset for the rotary axes of the swivel data set as offset
Bit 8 is set in conjunction with MD21186.
Swivel data set TC permanently assigned to the tool
= 0 Show number of the swivel data set TC
= 1 Do not show number of the swivel data set TC
The swivel data set is assigned to the tool with parameter SGUD_TC_GNO if technology
MD52200 = 3 is set for cylindrical grinding.
Example:
The machine machine manufacturer can write the current tool _TC_GNO = $P_TOOLNO
into parameter _TC_GNO in the tool change program L6. As a result, the tool holder will
be updated when a tool is changed.
Swivel plane: Show input field "Positioning direction"
= 0 Input field "Positioning direction" is not displayed.
= 1 Input field "Positioning direction" is displayed with swivel table and swivel head/table
combinations.
The selected positioning direction is stored in GUD _TC_POS_DIR and can be evaluated
in CUST_800:
_TC_POS_DIR = 0: Automatic (shortest path)
_TC_POS_DIR = -1: Direction -
_TC_POS_DIR = +1: Direction +
The function must be implemented by the manufacturer.
Positioning both solutions of AB kinematics
= 0 Positions only one solution of some swivel angles (compatibility)
= 1 Positions both solutions calculated by the NC
Bit 11 should be set for kinematics = 1 where, in the kinematics basic setting, neither of
the two rotary axes rotates about the tool axis (AB kinematics in tool axis in the Z direction)
Swivel plane, align tool: Reset behavior takes account of rotary axis positions
= 0 Reset condition refers to the final position of the rotary axes of the swivel data set (com‐
patibility)
Linear axis identifiers are written into parameters $TC_CARR21/22. On reset (TCOABS),
the tool holder is initialized with the final positions of the rotary axes ($TC_CARR13/14).
= 1 Reset condition refers to the current position of the rotary axes of the swivel data set
The rotary axis names of the swivel data set are written into parameters $TC_CARR21/22.
On reset (TCOABS), the tool holder is initialized with the actual values of the rotary axes.
Activation of extended evaluation of the rotations with axis swiveling in pole position
= 0 No evaluation of the rotations with swiveling in pole position (compatibility), the setting of
bits 4 and 11 apply
= 1 Activation of extended evaluation of the rotations with swiveling in pole position
