Typical Setup

The Robot and its Axes

The Controller

The Operator Panel

When in “AUTO” mode

The Operator Panel (cont) The Two/Three Mode Switch

Teach Modes (T1, etc) Must be in this mode to develop a program using the teach

pendent. Top robot movement speed is limited

AUTO After a program is developed, turn off the teach pendent and

flip to AUTO. The ‘current’ program that was being edited by the teach

pendent can now be run by pressed the Cycle Start button Note that program execution can start at any line in

the program.

The Teach Pendent

NOTE: Squeeze Deadman switch only half way – full compression generate an E-Stop… (electricuted people usually squeeze their hands very hard….)

Programming

Teach Pendent Programming (TPP)

Example Display and TPP Program

Types of Instructions

Motion instruction: Moves the tool to the target position within the operating range.

Additional motion instruction: Performs an additional (special) operation during a motion.

Register instruction: Places (loads) numerical data into a register.

Position register instruction: Places (loads) position data into a register.

Input/output instruction: Sends or receives a signal to or from a peripheral unit.

Branch instruction: Changes the flow of a program.

Types of Instructions (cont)

Wait instruction: Holds execution of the program until the specified conditions are satisfied.

Routine call instruction: Calls and executes a subprogram. Macro instruction:

Calls a specified program and executes it.

Palletizing instruction: Palletizes workpieces. Program end instruction: Terminates execution of a program. Comment instruction: Adds a comment to a program. Other instructions

Programming Program Detail Screen

Setup/edit program header information

Program Sub types Job (JB)

This represents a main program that can be started using a device such as a teach pendant. Process programs are called in a main program for execution.

Process (PR) This represents a subprogram that is called by a job program for

execution of a particular job.

Macro (MR) This represents a program for executing a macro instruction. The

subtype of a program registered on the macro instruction setting screen is automatically set to MR.

State: Specify this when creating a conditional program with the state

monitoring function.

Group Masks

The Robot control unit can divide up to 40 axes (when a multifunction board is inserted) into up to five operation groups and control those groups simultaneously. A single group can control up to nine axes (multimotion function). If the system has only one operation group, the default motion group is group 1 (1, *, *, *, *).

Editing a program Each line is numbered Each line is created using the built-in menus [End] symbolizes the end of the program

Executing a program In Teach Mode:

Deadman switch must be pushed in. Clear any faults.

Push the “RESET” button when all faults are cleared. Push SHIFT + FWD

NOTE: Will execute program from the current line in the program.

Push SHIFT + BWD to execute the program instructions in reverse order

In Auto Mode: Push in the Cycle Start button Teach pendent must be turned off

Motion Commands

Motion Commands (cont)

Types of Motion

Joint (J) When Joint is selected, the tool is moved

arbitrarily between two specified points. Linear (L)

When Linear is selected, the tool is moved along a straight line between the two specified points.

Circular (C) When Circular is selected, the tool is moved along

an arc connecting three specified points.

Circular Motion

Fine versus Continuous “Attitudes”

Changing Robot Job speed (feedrate)

Calculating final speed of robot during a motion

Teaching Points

When a motion instruction is taught, position data is written to the program at the same time.

Two types of positions possible Joint – joint angles Cartesian – X, Y, Z, Yaw, Pitch, Roll

Cartesian (point) Locations Information Stored:

Configuration:

Viewing the detailed point information

Joint Locations

Location Variable Types

Two types of location variables Location Variables

A position number is automatically assigned each time a motion instruction is taught and it is reflected in the program: P[1], P[2], etc…

Deleted a location, does not change numbering Location Registers

Same idea, but like global variables. 100 provided.

Add descriptive comments to each location Just press ENTER when cursor is at that point

Other Variables (“Registers”)

“Registers” are used to store data – integers, etc So, not “typical” variables…

Two hundred are provided. R[1], R[2], … , R[200]

Variables

Branch Instructions

The label instruction (LBL[i]) is used to specify a program execution branch destination.

The JMP LBL[i] instruction transfers program control to a specified label.

If Statement (Conditional Branch)

Step by Step Example of Creating and Running a new program When looking at the list of programs, click the

F2 key which corresponds to the “CREATE” button.

Step by Step Example Type in the program name.

Use Arrow Keys to choose type of characters

Use F Keys to type characters

Step by Step Example

Press F1 Key to insert a new motion command

The robot is currently “at” this location

Press F5 Key to modify a taught location

Press NEXT to go to next screen of commands

Step by Step Example

Press F1 Key to insert a new instruction. We’ll choose the JMP/LBL in order to create a loop in this example.

Step by Step Example Program is ready to

execute. Use arrows to move the

cursor the first line that you would like to execute.

Hold-in deadman switch (1/2 way) 1. Press the RESET key to

clear faults.

2. Hold-in SHIFT and press FWD

Step by Step Example

When the program is completely developed and tested, the program can be run in operation mode: Switch the teach pendant “ off ” Switch the Mode button on the Operator Panel

(on the controller) to AUTO Press the CYCLE START button on the operator

panel
