Magnitude Determines Direction denotes that the system uses the sign algebraically to determine the angular position. B-90 and B90 are different positions on the rotary axis and are 180 degrees apart. Rotation to a larger angle is always clockwise and rotation to a smaller angel is always counter clockwise. Typically the travel limits on this type of table are more than 360 degrees (i.e. -9999 to 9999)
Magnitude Determines Direction是指系统按照代数运算法则来决定工作台旋转方向的。B-90 和 B90是不同的两个点，相差180。因此工作台从小角度旋转到大角度总是顺时针而从大角度旋转到小角度总是逆时针旋转。所以角度值范围可以大于360(i.e. -9999 to 9999)。
Sign Determines Direction means that the system uses sign only for direction of rotation. B90 and B-90 are the same position on the rotary table. When you select B90 the table rotates clockwise from its current location to 90. When you select B-90 the table rotates counterclockwise from its current location to 90. Typically, the limits on this table are from 0 to 360.

Sign Determines Direction是指系统仅仅按照正负号来决定工作台旋转方向。B-90 和 B90是相同的两个点。B90是指工作台从当前位置顺时针旋转到90，B-90是指工作台从当前位置逆时针旋转到90。所以角度值范围只能从0到360。
Pivot Distance
This option is not valid for the dual rotary type five-axis machine tool. You can define the distance from the pivot point to the spindle gage point. This value may be specified with either the fourth or the fifth axis dialogs, however there is only one pivot distance on the machine tool.
Angular Offset
Use this option when a tool axis of (0,0,1) does not result in angular positions of 0.0 for the fourth axis. The system needs this offset for some Sundstrand head/table machine tools. Enter the value that needs to be added to adjust the rotary angle (usually -90).
