Position Constants; Coordinate, Posture And Additional Axis Data Types And Meanings; Meaning Of Structure Flag Data Type And Meanings - Mitsubishi MELFA CR1D Instruction Manual

4.3.12 Position constants

The syntax for position constants is as shown below. Variables cannot be described within position con-
stants.
( 100, 100,
Example)
P1=( 300, 100, 400, 180, 0, 180, 0, 0 ) ( 7, 0 )
P2=( 0, 0, -5, 0, 0, 0 ) ( 0, 0 )
P3=( 100, 200, 300, 0, 0, 90 ) ( 4, 0 ) [A case of a 4-axis horizontal multi-joint robot]

(1) Coordinate, posture and additional axis data types and meanings

[Format] X, Y, Z, A, B, C , L1, L2
[Meaning] X, Y, Z: coordinate data. The position of the tip of the robot's hand in the XYZ coordinates.
(The unit is mm.)
A, B, C: posture data. This is the angle of the posture. (The unit is deg.)
L1, L2: additional axis data. These are the coordinates for additional axis 1 and additional axis 2,
respectively. (The unit is mm or deg.)
Note1) The T/B and Personal computer support software display the unit in deg; however, the unit
of radian is used for substitution and calculation in the program.

(2) Meaning of structure flag data type and meanings

[Format] FL1, FL2
[Meaning] FL1: Posture data. It indicates the robot arm posture in the XYZ coordinates.
FL2: Multiple rotation data. It includes information of the rotational angle of each joint axis at the
position (XYZ) and posture (ABC) expressed as XYZ coordinates.
Default value = 0 (The range is 0 to +4294967295 ... Information for eight axes is held with a
1-axis 4-bit configuration.)Two types of screens are available for the PC: screens that dis-
play the number of rotations for each axis (-8 to 7) in decimal and those that display the
number of rotations for each axis in hexadecimal.
