Operating Instructions COMPAX-M / -SAbsolute positioning [POSA]968.4.1 Absolute positioning [POSA]Reference point is real zero (RZ).Positioning is executed with the acceleration speed set using ACCEL and thevelocity set using SPEED. If these values have not previously been set, substitutevalues will apply:SPEED: parameter P2; ACCEL: parameter P6 (see Page 212)POSA valueValue: figure with two digits after the decimal point (three for inches) in the unitdefined in P90; a control parameter (P40..P49) or a variable (V1..V39)e.g. POSA .P40The range is defined by the software end limits P11 and P12.N005: POSA 150.50 Absolute positioning to +150.5 unitsN006: POSA -500 Absolute positioning to -500 units♦ A position approached manually can be transferred as a POSA command into apreviously selected data record using "TEACH data record" (via an interface).♦ POSA HOME command via interface triggers "find machine zero".POSA HOME is not permitted in the COMPAX ñ program.When in continuous mode, relative positioning is also adopted with POSA.8.4.2 Relative positioning [POSR]The reference point is the current position.POSR valueValue: two digits after the decimal point (three for inches) in the unit defined inP90; a control parameter (P40..P49) or a variable (V1..V39)e.g. POSR .P40The range is defined by the software end limits P11 and P12.N005: POSR 2000N006: POSR-100.25Relative positioning by +2000Relative positioning by -100.25The positioning commands POSR and POSA can be controlled using binary input I15 "Fast start". Thisfunction is switched on using P18. COMPAX then waits until I15="1" before it executes POSR orPOSA (see Page 151).POSASyntax:Example:Additional function:POSRSyntax:Example:POSAPOSRSPEEDACCELOUTPUTPasswordSPEEDSYNCMarkreferencePOSRSPEEDPOSROUTPUTCamcontrollerWAITGOTOGOSUBRETURNENDREPEATIF I..ComparisonWAIT StartGOTO /GOSUB EXTIF Error/ StopArithmeticPositionmonitoringIdle displaySpeedmonitoringEngage /disengagebrake / finalstageVariablevoltage
