D Series Controller 1. Overview of the AS System Kawasaki Robot AS Language Reference Manual

1.0 OVERVIEW OF AS

The Kawasaki robots are controlled by a software-based system called AS. This chapter describes the overall view of the AS system.

1.1 System Overview

1.2 Characteristics of the AS System

1.3 AS System Configuration

1-1

D Series Controller 1. Overview of the AS System Kawasaki Robot AS Language Reference Manual

1.1 OVERVIEW OF THE AS SYSTEM

In the AS system, you can place commands or execute programs using AS language. The AS system is written in the nonvolatile memory in the robot control unit. When the control power is turned on, the AS system starts and waits for a command to be input.

The AS system controls the robot according to the given commands and programs. It can also execute several types of functions while a program is running. Some of the functions that can be used while a program is running are: displaying the system status or the robot pose (location), saving data in external memory devices, and writing/editing programs.

1-2

D Series Controller 1. Overview of the AS System Kawasaki Robot AS Language Reference Manual

1.2 CHARACTERISTICS OF THE AS SYSTEM

In the AS system, the robots are controlled and operated based on a program that describes the necessary tasks and which is made prior to the operation. (Teaching Playback Method)

AS language can be divided into two types: monitor commands and program instructions.

Monitor commands: Used to write, edit, and execute programs. They are entered after

the prompt (>) shown on the screen, and are immediately executed. Some of the monitor commands are used within the program s to work as program instructions.

Program instructions: Used to direct the movements of the robot, to monitor or to control

external signals, etc. in programs. A program is a collection of program instructions.

In this manual, a monitor command is referred to as a command, a program instruction as an instruction.

AS is unique in the following ways:

1. The robot can be moved along a continuous path trajectory.（CP motion: Continuous

Path motion）

2. Two coordinate systems, base coordinates and tool coordinates, are provided, for more

precise control of the robot’s movements.

3. The coordinates can be shifted or rotated corresponding to the pose changes of the work.

4. When teaching locations or repeating executions, the robot can be moved along a linear

path while keeping the tool posture.

5. Programs can be named freely and saved without limits in numbers.

6. Each operation unit can be defined as a program and these programs can be combined to

make a complex one. (Subroutine)

7. By monitoring signals, programs can be interrupted and branched to a different program

suspending current motions when an external signal is input. (Interruption )

8. A Process Control program (PC program) can be executed simultaneously with a robot

control program.

9. Programs and pose (location) data can be displayed on terminals and saved in devices

such as the PC card.

10. Programming can be done using a personal computer loaded with the terminal softwa re

(KRterm or KCwin32) provided by Kawasaki. （Off-line programming）

D Series Controller 2. AS System Kawasaki Robot AS Language Reference Manual

2.1 AS SYSTEM STATUS

The AS system consists of the following three modes:

1. Monitor Mode

This is the basic mode in the AS system. Monitor commands are executed in this mode. Editor or Playback Mode is accessed from this mode.

2. Editor Mode

This mode enables you to create a new program or modify an existing one. Only editor commands are executed by the system in this mode.

3. Playback Mode

The system is in Playback Mode during program execution. Computations for robot motion control are performed and commands entered from the terminal are processed during unoccupied CPU time. Some monitor commands cannot be executed in this mode.

2-2

D Series Controller 2. AS System Kawasaki Robot AS Language Reference Manual

2.2 AS SYSTEM SWITCHES

The following system switches can be set in the AS System using the monitor command SWITCH. The status and the conditions set for each switch can be checked or changed from the terminal.

1. CHECK.HOLD

Determines whether or not to respond to the EXECUTE, DO, STEP, MSTEP, and CONTINUE commands when the HOLD/RUN switch is in the HOLD position.

2. CP

Enables or disables continuous path movement. When this switch is ON, the robot makes smooth transitions between motion segments. When it is OFF, the robot decelerates and stops at the end of each motion segment.

3. CYCLE.STOP

Determines whether to keep ON or to turn OFF CYCLE START when an external hold signal is input to stop the motion of the robot.

4. MESSAGES

Enables or disables message output to the terminal in response to the PRINT or TYPE command.

5. OX.PREOUT

Sets the timing for OX signal output in block instructions, allowing for earlier signal output at the memory change instead of at the accuracy setting.

6. PREFETCH.SIGINS

Sets the timing for signal output in AS language programs, and has the same effect on signal timing as OX.PREOUT.

7. QTOOL

When in TEACH mode, determines whether or not to change the tool transformation according to the tool number taught in block instructions.

8. REP ONCE (Repeat Once)

When this switch is ON, the program runs one time. When it is OFF, the program runs continuously.

2-3

D Series Controller 2. AS System Kawasaki Robot AS Language Reference Manual

9. RPS (Random Program Selection)

Enables or disables the selection of programs based on the binary status of external signals.

10. SCREEN

Enables or disables the scrolling of the screen when the information is too large to fit in one screen.

11. STP ONCE

Sets whether the program is performed one step at a time or continuously.

Refer to 5.6 Monitor Command SWITCH, ON, OFF for further information on how to set the system switches.

2-4

D Series Controller 2. AS System Kawasaki Robot AS Language Reference Manual

2.3 AS SYSTEM SETUP

The following system settings can be changed depending on the need, using the monitor commands.

1. Zeroing (ZZERO command)

ZZERO command is used to set the encoder value to correspond to a robot’s known mechanical position. When replacing the servo motor or performing maintenance on an encoder, the encoder value will need adjustment using this command. (This command is for maintenance purposes only.)

2. Clamp setting (HSETCLAMP command)

This setting is made prior to shipment from the factory. The settings, single/double and output spec (ON when closed /OFF when closed), can be changed using HSETCLAMP command. However, the change will only affect the software, so be sure to check if it is consistent with the hardware.

3. Maximum number of input and output signals (ZSIGSPEC command)

ZSIGSPEC command sets the maximum number of input and output signals that can be used. It is set prior to shipment from the factory. (This is a default setting that function as a software error check, thus be sure it is consistent with the hardware.)

4. Software Dedicated Signals (DEFSIG command)

In addition to the Hardware dedicated signals, there are I/O signals in the software that can be used as dedicated signals (Software dedicated signals). The signals in the table be low can be used as Software dedicated signals. Note that since the number of I/O signals in the software is the sum of Software dedicated signals and General purpose signals, the number of General purpose signal decreases as more Software dedicated signals are used.

2.4 INPUT/OUTPUT CONTROL

2.4.1 TERMINAL CONTROL

Data and commands input at a terminal are first received by the system buffer. Then they are read by the monitor or program and echoed or displayed on the terminal screen. The maximum number of characters that can be input at a terminal is 128, and additional characters input are ignored.

Output of data to a terminal can be controlled using the PRINT and TYPE instructions. 8 bits are displayed on the terminal screen. Unless format is specified using specification code “/S” with the PRINT/TYPE instruction, data are displayed with a new line starting after each command. (See 6.8 Message Control Instructions for detailed information.)

Terminal input and output can be controlled using the below commands. These are called the terminal control commands. The Ctrl (Control Key) is pressed with each alphabetical character (the character may be either lower or upper case letters). Unlike other AS commands, there is no need to press the ENTER key after these command.

Commands Functions

Ctrl + S

Stops the scrolling of the display terminal. Ctrl + Q Resumes the data output stopped by Ctrl + S . Ctrl + C Ctrl + H

Ctrl + M
