Offset / Scaling (Cplintr, Cplinsc, Cplouttr, Cploutsc) - Siemens SINUMERIK 840D sl Function Manual

M3: Coupled axes
8.5 Generic coupling
Example:
Programming
CPMPRT[X2]="ON"
Constraints
● The coupling characteristics set with CPMPRT is retained until the coupling module is deleted
with (CPDEL).
● If CPMPRT="NONE" is set, then the response at part program start during search run via
program test (SERUPRO) is defined by CPMSTART.
● For the set coupling type (CPSETTYPE="TRAIL", "LEAD", "EG" or "COUP"), the response
is defined by the following machine data at part program start during search run via program
test:
MD22620 $MN_START_MODE_MASK_PRT(definition of initial control system settings
with special start)
MD22621 $MC_ENABLE_START_MODE_MASK_PRT (activation of MD22620)
MD20112 $MC_START_MODE_MASK (Definition of the control default settings in case of
NC START)

Offset / scaling (CPLINTR, CPLINSC, CPLOUTTR, CPLOUTSC)

An existing coupling relationship between a following axis and a leading axis can be scaled
and offset.
The effect of these functions on the total setpoint value of the following axes can be viewed
from the following formula:
FA
Total
FA
Cmd
LA
1 / 2
SynPosLA
1 / 2
scaleIn
1 / 2
transIn
1 / 2
KF

scaleOut
1 / 2
transOut

Note
The scaling and offset values can be defined for each leading axis.
400
Total setpoint value of the following axis
Setpoint set in the part program
Setpoint or actual value of the 1st or 2nd leading axis/value
Synchronized position of the 1st or 2nd leading axis/value
Scaling factor of the 1st or 2nd lead value
Offset of the 1st or 2nd lead value
Coupling factor of the 1st or 2nd leading axis/value
Scaling factor of the 1st or 2nd output value
Offset of the 1st or 2nd output value
Comment
; At part program start during search run via program
test, coupling to following axis X2 is switched on.
