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

M3: Coupled axes
14.5 Generic coupling
Supplementary conditions
● The coupling characteristics set with CPMPRT is retained until the coupling module is deleted
with (CPDEL).
● If CPMPRT="NONE" is set, then the response when the part program starts under block
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 when the part program starts during block 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 initial control settings for NC-START)
→ See Section "Defaults" in " Coupling types (CPSETTYPE) (Page 543) ".

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:
