This page details the Register Instructions available on the Fanuc Teach Pendant Programmers.
Register instructions do not involve motion. They are simply math operations with one or more inputs and an output.
When the program reaches a register instruction, it completes the math operation, overwrites the destination variable, and moves forward.
Equals Instruction
| R | [1] | = | R | [2] | Equals Instruction |
|---|---|---|---|---|---|
| PR | [1] | = | PR | [2] | |
| PR | [i,j] | = | 1 | ||
| R | [1] | = | PR | [i,j] |
When this instruction is reached
The contents of the left variable are set to the right variable.
When to add this instruction
Use this instruction whenever you need to set a variable’s contents to the contents of another.
In the Non-Motion Instructions menu, select the “Registers” Category. In the “Registers” menu, select “... = ...”. Once inserted, select your left variable. Type the numbers for the variable, then hit enter. Select the right variable. Type the numbers for the variable, then hit enter.
What else is needed to use this instruction
None.
Valid Variables
R [1] - Data Registers
PR [1] - Position Registers (Must set all 6 elements at once)
PR [i,j] - Position Register Element (Sets element j in position register i)
SR [1]
PL [1]
Constant
Special Notes
You cannot perform operations between entire position registers and other variables, as position registers contain 6 separate elements. You can only work with one element at a time, using PR[i,j].
Addition Instruction
| R | [1] | = | R | [1] | + | 28 | Add Instruction | |
|---|---|---|---|---|---|---|---|---|
| PR | [1] | = | PR | [1] | + | PR | [7] | |
| PR | [i,j] | = | R | [3] | + | 100 | ||
| R | [1] | = | PR | [i,j] | + | PR | [i,j] |
When this instruction is reached
The contents of the left variable are set to the middle variable plus the right variable.
When to add this instruction
Use this instruction whenever you need to set a variable’s contents to the contents of multiple variables added together.
What else is needed to use this instruction
None.
Valid Variables
R [1] - Data Registers
PR [1] - Position Registers (Must set all 6 elements at once)
PR [i,j] - Position Register Element (Sets element j in position register i)
SR [1]
PL [1]
Constant
Special Notes
You cannot perform operations between entire position registers and other variables, as position registers contain 6 separate elements. You can only work with one element at a time, using PR[i,j].
Subtraction Instruction
| R | [1] | = | R | [1] | - | 28 | Subtract Instruction | |
|---|---|---|---|---|---|---|---|---|
| PR | [1] | = | PR | [1] | - | PR | [7] | |
| PR | [i,j] | = | R | [3] | - | 100 | ||
| R | [1] | = | PR | [i,j] | - | PR | [i,j] |
When this instruction is reached
The contents of the left variable are set to the middle variable minus the right variable.
When to add this instruction
Use this instruction whenever you need to subtract one variable from another.
What else is needed to use this instruction
None.
Valid Variables
R [1] - Data Registers
PR [1] - Position Registers (Must set all 6 elements at once)
PR [i,j] - Position Register Element (Sets element j in position register i)
SR [1]
PL [1]
Constant
Special Notes
You cannot perform operations between entire position registers and other variables, as position registers contain 6 separate elements. You can only work with one element at a time, using PR[i,j].
Division Instruction
| R | [1] | = | R | [1] | / | 28 | Division Instruction | |
|---|---|---|---|---|---|---|---|---|
| PR | [1] | = | PR | [1] | / | PR | [7] | |
| PR | [i,j] | = | R | [3] | / | 100 | ||
| R | [1] | = | PR | [i,j] | / | PR | [i,j] |
When this instruction is reached
The contents of the left variable are set to the middle variable divided by the right variable.
When to add this instruction
Use this instruction whenever you need to divide two variables.
What else is needed to use this instruction
None.
Valid Variables
R [1] - Data Registers
PR [1] - Position Registers (Must set all 6 elements at once)
PR [i,j] - Position Register Element (Sets element j in position register i)
SR [1]
PL [1]
Constant
Special Notes
You cannot perform operations between entire position registers and other variables, as position registers contain 6 separate elements. You can only work with one element at a time, using PR[i,j].
