1 Instructions1.1 AccSet - Reduces the acceleration

UsageAccSet is used when handling fragile loads. It allows slower acceleration anddeceleration, which results in smoother robot movements.This instruction can only be used in the main task T_ROB1 or, if in a MultiMovesystem, in Motion tasks.

Basic examplesThe following examples illustrate the instruction AccSet:

Example 1AccSet 50, 100;

The acceleration is limited to 50% of the normal value.

Example 2AccSet 100, 50;

The acceleration ramp is limited to 50% of the normal value.

ArgumentsAccSet Acc Ramp

Acc

Data type: numAcceleration and deceleration as a percentage of the normal values. 100%corresponds to maximum acceleration. Maximum value: 100%. Input value < 20%gives 20% of maximum acceleration.

Ramp

Data type: numThe rate at which acceleration and deceleration increases as a percentage of thenormal values. Jerking can be restricted by reducing this value. 100% correspondsto maximum rate. Maximum value: 100%. Input value < 10% gives 10% of maximumrate.




The figures show that reducing the acceleration results in smoother movements.

Ti

xx0500002146

Program executionThe acceleration applies to both the robot and external axes until a new AccSetinstruction is executed.The default values (100%) are automatically set

at a P-Start. when a new program is loaded. when starting program execution from the beginning.

SyntaxAccSet

[ Acc ':=' ] < expression (IN) of num > ','

[ Ramp ':=' ] < expression (IN) of num > ';'

1.2 ActEventBuffer - Activation of event buffer

DescriptionActEventBuffer is used to activate the use of the event buffer in current motionprogram task.The instructions ActEventBuffer and DeactEventBuffer should be used whencombining an application using finepoints and a continuous application wheresignals needs to be set in advance due to slow process equipment.This instruction can only be used in the main task T_ROB1 or, if in a MultiMovesystem, in Motion tasks.

Basic examplesThe following example illustrates the instruction ActEventBuffer:

Example 1..

DeactEventBuffer;

! Use an application that uses finepoints, such as SpotWelding

..

! Activate the event buffer again

ActEventBuffer;

! Now it is possible to use an application that needs

! to set signals in advance, such as Dispense

..

The DeactEventBuffer deactivates the configured event buffer. When using anapplication with finepoints, the start of the robot from the finepoint will be faster.When activating the event buffer with ActEventBuffer, it is possible to set signalsin advance for an application with slow process equipment.

Program executionThe use of an event buffer applies for the next executed robot movement of anytype, and is valid until a DeactEventBuffer instruction is executed.The instruction will wait until the robot and external axes has reached the stoppoint (ToPoint of current move instruction) before the activation of the eventbuffer. Therefore it is recommended to program the movement instruction precedingActEventBuffer with a fine point.The default value (use event buffer = TRUE) is automatically set

at a P-Start. when a new program is loaded. when starting program execution from the beginning.

LimitationsActEventBuffer cannot be executed in a RAPID routine connected to any of thefollowing special system events: PowerOn, Stop, QStop, Restart or Step.

1.3 ActUnit - Activates a mechanical unit

UsageActUnit is used to activate a mechanical unit.It can be used to determine which unit is to be active when, for example, commondrive units are used.This instruction can only be used in the main task T_ROB1 or, if in a MultiMovesystem, in Motion tasks.

Basic examplesThe following example illustrates the instruction ActUnit:

Example 1ActUnit orbit_a;

Activation of the orbit_a mechanical unit.

ArgumentsActUnit MechUnit

MechUnit

Mechanical UnitData type: mecunitThe name of the mechanical unit to be activated.

Program executionWhen the robots and the actual path of external axes are ready, the path on currentpath level is cleared and the specified mechanical unit is activated. This meansthat it is controlled and monitored by the robot.If several mechanical units share a common drive unit, activation of one of thesemechanical units will also connect that unit to the common drive unit.

LimitationsIf this instruction is preceded by a move instruction, that move instruction must beprogrammed with a stop point (zonedata fine), not a fly-by point, otherwise restartafter power failure will not be possible.ActUnit cannot be executed in a RAPID routine connected to any of the followingspecial system events: PowerOn, Stop, QStop, Restart, Reset or Step.It is possible to use ActUnit - DeactUnit on StorePath level, but the samemechanical units must be active when doing RestoPath as when StorePathwasdone. Such operation on the Path Recorder and the path on the base level will beintact, but the path on the StorePath level will be cleared.

SyntaxActUnit

[MechUnit ':=' ] < variable (VAR) of mecunit> ';'

1.4 Add - Adds a numeric value

UsageAdd is used to add or subtract a value to or from a numeric variable or persistent.

Basic examplesThe following examples illustrate the instruction Add:

Example 1Add reg1, 3;

3 is added to reg1, that is,reg1:=reg1+3.

Example 2Add reg1, -reg2;

The value of reg2 is subtracted from reg1, that is,reg1:=reg1-reg2.

Example 3VAR dnum mydnum:=5;

Add mydnum, 500000000;

500000000 is added to mydnum, that is,mynum:=mynum+500000000.

Example 4VAR dnum mydnum:=5000;

VAR num mynum:=6000;

Add mynum, DnumToNum(mydnum \Integer);

5000 is added to mynum, that is, mynum:=mynum+5000. You have to use DnumToNumto get a num numeric value that you can use together with the num variable mynum.

ArgumentsAdd Name | Dname AddValue | AddDvalue

Name

Data type: numThe name of the variable or persistent to be changed.

Dname

Data type: dnumThe name of the variable or persistent to be changed.

AddValue

Data type: numThe value to be added.

AddDvalue

Data type: dnumThe value to be added.



1 Instructions1.4 Add - Adds a numeric value

LimitationsIf the value to be added is of the type dnum, and the variable/persistent that shouldbe changed is a num, a runtime error will be generated. The combination ofarguments is not possible (see Example 4 above how to solve this).

SyntaxAdd

[ Name ':=' ] < var or pers (INOUT) of num >

| [ Dname := ] < var or pers (INOUT) of dnum > ,

[ AddValue ':=' ] < expression (IN) of num >

| [ AddDvalue := ] < expression (IN) of dnum > ;

1.5 AliasIO - Define I/O signal with alias name

UsageAliasIO is used to define a signal of any type with an alias name or to use signalsin built-in task modules.Signals with alias names can be used for predefined generic programs, withoutany modification of the program before running in different robot installations.The instruction AliasIO must be run before any use of the actual signal. SeeBasic examples on page 27 for loaded modules, and More examples on page 28for installed modules.

Basic examplesThe following example illustrates the instruction AliasIO:See also More examples on page 28.

Example 1VAR signaldo alias_do;

PROC prog_start()

AliasIO config_do, alias_do;

ENDPROC

The routine prog_start is connected to the START event in system parameters.The program defining digital output signal alias_do is connected to the configureddigital output signal config_do at program start.

ArgumentsAliasIO FromSignal ToSignal

FromSignal

Data type: signalxx or stringLoaded modules:The signal identifier named according to the configuration (data type signalxx)from which the signal descriptor is copied. The signal must be defined in the I/Oconfiguration.Installed modules or loaded modules:A reference (CONST, VAR or parameter of these) containing the name of the signal(data type string) from which the signal descriptor after search in the system iscopied. The signal must be defined in the I/O configuration.

ToSignal

Data type: signalxxThe signal identifier according to the program (data type signalxx) to which thesignal descriptor is copied. The signal must be declared in the RAPID program.The same data type must be used (or found) for the arguments FromSignal andToSignal and must be one of type signalxx (signalai, signalao, signaldi,signaldo, signalgi, or signalgo).



1 Instructions1.5 AliasIO - Define I/O signal with alias name

Program executionThe signal descriptor value is copied from the signal given in argument FromSignalto the signal given in argument ToSignal.

Error handlingThe following recoverable errors are generated and can be handled in an errorhandler. The system variable ERRNO will be set to:

The FromSignal is not defined in the IO configurationERR_ALIASIO_DEFor the ToSignal is not declared in the RAPID programor the ToSignal is defined in the IO configuration.

The data types for the arguments FromSignal and ToSignalis not the same type.

ERR_ALIASIO_TYPE

More examplesMore examples of the instruction AliasIO are illustrated below.

Example 1VAR signaldi alias_di;

PROC prog_start()

CONST string config_string := "config_di";

AliasIO config_string, alias_di;

ENDPROC

The routine prog_start is connected to the START event in system parameters.The program defined digital input signal alias_di is connected to the configureddigital input signal config_di (via constant config_string) at program start.

LimitationWhen starting the program, the alias signal cannot be used until the AliasIOinstruction is executed.Instruction AliasIOmust be placed

either in the event routine executed at program start (event START) or in the program part executed after every program start (before use of the

signal)To prevent mistakes it is not recommended to use dynamic reconnection of anAliasIO signal to different physical signals.

SyntaxAliasIO

[ FromSignal ':=' ] < reference (REF) of anytype> ','

[ ToSignal ':=' ] < variable (VAR) of anytype> ';'

1.6 ":=" - Assigns a value

UsageThe := instruction is used to assign a new value to data. This value can beanything from a constant value to an arithmetic expression, forexample,reg1+5*reg3.

Basic examplesThe following examples illustrate the instruction :=:See also More examples on page 30.

Example 1reg1 := 5;

reg1 is assigned the value 5.

Example 2reg1 := reg2 - reg3;

reg1 is assigned the value that the reg2-reg3 calculation returns.

Example 3counter := counter + 1;

counter is incremented by one.

ArgumentsData := Value

Data

Data type: AllThe data that is to be assigned a new value.

Value

Data type: Same as DataThe desired value.

More examplesMore examples of the instruction := are illustrated below.

Example 1tool1.tframe.trans.x := tool1.tframe.trans.x + 20;

The TCP for tool1 is shifted 20 mm in the X-direction.

Example 2pallet{5,8} := Abs(value);

An element in the pallet matrix is assigned a value equal to the absolute valueof the value variable.

LimitationsThe data (whose value is to be changed) must not be

a constant

1.9 BookErrNo - Book a RAPID system error number

UsageBookErrNo is used to book a new RAPID system error number.

Basic examplesThe following example illustrates the instruction BookErrNo:

Example 1! Introduce a new error number in a glue system

! Note: The new error variable must be declared with the initialvalue -1

VAR errnum ERR_GLUEFLOW := -1;

! Book the new RAPID system error number

BookErrNo ERR_GLUEFLOW;

The variable ERR_GLUEFLOW will be assigned to a free system error number foruse in the RAPID code.

! Use the new error number

IF di1 = 0 THEN

RAISE ERR_GLUEFLOW;

ELSE

...

ENDIF

! Error handling

ERROR

IF ERRNO = ERR_GLUEFLOW THEN

...

ELSE

...

ENDIF

If the digital input di1 is 0, the new booked error number will be raised and thesystem error variable ERRNO will be set to the new booked error number. The errorhandling of those user generated errors can then be handled in the error handleras usual.

ArgumentsBookErrNo ErrorName

ErrorName

Data type: errnumThe new RAPID system error variable name.

LimitationsThe new error variable must not be declared as a routine variable.The new error variable must be declared with an initial value of -1, that gives theinformation that this error should be a RAPID system error.
