-
Usage ManLoadIdProc (Manipulator Load Identification Procedure) is used for load identification of payload for external manipulators by executing a user defined RAPID program. This instruction can only be used in the main task T_ROB1 or, if in a MultiMove system, in Motion tasks. Note An easier way to identify the payload is to use the interactive dialogue RAPID program ManLoadIdentify.This program can be started from the menu ProgramEditor/Debug/Call Routine.../ManLoadIdentify. Basic examples Basic examples of the instruction ManLoadIdProc are illustrated below. PERS loaddata myload : [6,[0,0,0],[1,0,0,0],0,0,0]; VAR bool defined; ActUnit STN1; ManLoadIdProc \ParIdType : IRBP_L \MechUnit : STN1 \PayLoad : myload \ConfigAngle : 60 \AlreadyActive \DefinedFlag : defined; DeactUnit STN1; Load identification of payload myload mounted on the mechanical unit STN1. The external manipulator is of type IRBP-L. The configuration angle is set to 60 degrees. The manipulator is activated before the load identification and deactivated after. After the identification myload has been updated and defined it is set to TRUE. Arguments ManLoadIdProc [\ParIdType] [\MechUnit] | [\MechUnitName] [\AxisNumber] [\PayLoad] [\ConfigAngle] [\DeactAll] | [\AlreadyActive] [DefinedFlag] [DoExit] [ \ ParIdType ] Data type: paridnum Type of parameter identification. Predefined constants are found under the datatype paridnum. [ \ MechUnit ] Data type: mecunit Mechanical unit used for the load identification. Can not be used together with argument \MechUnitName. [ \ MechUnitName ] Data type: string Mechanical unit used for the load identification given as a string. Can not be used together with argument \MechUnit. [ \ AxisNumber ] Data type: num Axis number within the mechanical unit, which holds the load to be identified. [ \ PayLoad ] Data type: loaddata Variable for the payload to be identified. The component mass must be specified. This variable will be updated after the identification is done. [ \ ConfigAngle ] Data type: num Specification of a specific configuration angle ± degrees to be used for the parameter identification. Min. or - 30 degrees. Optimum or - 90 degrees. [ \ DeactAll ] Data type: switch If this switch is used all mechanical units in the system will be deactivated before identification is done. The mechanical unit to identify will then be activated. It cannot be used together with argument \AlreadyActive. [ \ AlreadyActive ] Data type: switch This switch is used if the mechanical unit to identify is active. It cannot be used together with argument \DeactAll. [ \ DefinedFlag ] Data type: bool This argument will be set to TRUE if the identification has been made, FALSE otherwise. [ \ DoExit] Data type: bool If set to TRUE the load identification will end up with an EXIT command to force the user to set PP to main before continuing the execution. If not present or set to FALSE no EXIT will be done. Note that ManLoadIdProc always clears the current path. Program execution All arguments are optional. If an argument is not given the user will be asked for the value from the FlexPendant (except for \DoExit). The user will always be asked to give the mass and if the manipulator is of type IRBP R, z in mm. The mechanical unit will carry out a large number of relative small transport and measurement movements. After all measurements, movements, and load calculations the load data is returned in argument Payload if used. The following load data is calculated. Manipulator type/ Calculated load data IRBP-K IRBP-L IRBP-C IRBP_T IRBP-R IRBP-A IRBP-B IRBP-D Parameter PayLoad - cog.x, cog.y, cog.z in loaddata in mm cog.x cog.y cog.x cog.y cog.x cog.y cog.x cog.y cog.z Parameter PayLoad - ix, iy, iz in loaddata in kgm2 iz iz ix iy iz ix iy iz The calculated data will be displayed on the FlexPendant. Limitations Usually load identification of load for the external manipulator is done with the service routine ManLoadIdentify. It is also possible to do this identification with this RAPID instruction ManLoadIdProc. Any path in progress will be cleared before the load identification. The program pointer will be lost after the load identification if argument \DoExit:TRUE is used. It is not possible to restart the load identification movements after any type of stop, such as program stop, emergency stop, or power failure. The load identification movements must be again restarted from the beginning. Error handling At any error during execution of the RAPID NOSTEPIN routine ManLoadIdProc the system variable ERRNO is set to ERR_PID_MOVESTOP, ERR_PID_RAISE_PP, or ERR_LOADID_FATAL and the program pointer is raised to the user call of ManLoadIdProc. Syntax ManLoadIdProc [ \ParIdType : expression (IN) of paridnum] [ \MechUnit : variable (VAR) of mecunit ] | [\ MechUnitName : expression (IN) of string] [ \ AxisNumber : expression (IN) of num ] [ \ PayLoad : var or pers (INOUT) of loaddata [ \ ConfigAngle : expression (IN) of num] [ \ DeactAll] | [ \ AlreadyActive] [ \ DefinedFlag : variable (VAR) of bool ] [ \ DoExit : expression (IN) of bool ] ;
