R-30IB EXAM QUESTIONS AND CORRECT
ANSWERS



\Q\.what are the 4 kinds of motion instructions - ANSWERS✔-- motion type

- positional information

- speed

- termination type



\Q\.what are the three kinds of motion types - ANSWERS✔-• J - Joint motion (moving the
required points at the same time to reach the desired position

• L - Linear motion (move in a straight line from start to end position)

• C - Circular motion (move in an arc from start to end point thru an intermediate position)



\Q\.how do you write a position - ANSWERS✔-P[1] is the position number ranging from 1 -
32767



\Q\.how do you write speed - ANSWERS✔-100% is the speed ranging from 1 to 100 of default
speed



write as percentage



\Q\.two termination types - ANSWERS✔-FINE & CNT

, FINE means robot stop at the point; it can be replaced with CNT (robot decelerate as it
approaches the point position)



\Q\.example of a motion instruction line - ANSWERS✔-J P[1] 100% FINE



\Q\.what are branching instructions for - ANSWERS✔-Enable a program to have a logical flow.



\Q\.examples of unconditional and conditional branching - ANSWERS✔-• Unconditional
branching - LBL, JMP LBL, CALL

• Conditional branching - Boolean Expression, Integer Expression



\Q\.be able to read - ANSWERS✔-• IF DI[1] = OFF, JMP LBL[1]

• J P[1] 100% FINE

• JMP LBL[2]

• LBL[1]

• J P[2] 100% FINE

• LBL[2]



\Q\.what do call instructions do - ANSWERS✔-Instruction to send program flow out to a sub-
program

ex:

• MAIN

• LBL[1]

• CALL PROG A

• CALL PROG B
