Keyword Coupling characteristics / mean‐
ing
Syntax
CPMBRAKE Response of the following axis
to certain stop signals and stop
commands
CPMBRAKE[FAx]=<bit-coded value>
CPMVDI Response of the following axis
to certain NC/PLC interface sig‐
nals
CPMVDI[FAx]=<bit-coded value>
CPMALARM Suppression of special cou‐
pling-related alarm outputs
CPMALARM[FAx]=<bit-coded value>
CPSETTYPE Coupling type CPSETTYPE[FAx]="<coupling type>"
"<coupling type>": "CP" Freely programmable
"TRAIL" Coupling type "Coupled
motion"
"LEAD" Coupling type "Master Val‐
ue Coupling"
"EG" Coupling type "Electronic
gearbox"
"COUP" Coupling type "Synchron‐
ized spindle"
FAx: Following axis/spindle
LAx: Leading axis/spindle
Note
Coupling characteristics, which are not explicitly programmed (in part program of synchronized
actions), become effective with their default settings.
Depending on the settings of the keyword CPSETTYPE instead of the default settings
(CPSETTYPE="CP") preset coupling characteristics can become effective.
Further information
For detailed information on generic couplings, see:
● Function Manual Axes and Spindles
3.16.7 Tangential control
3.16.7.1 Defining coupling (TANG)
Via the predefined procedure TANG(...), a tangential coupling between a rotary axis is defined
as the following axis and two geometry axes as the leading axes. The following axis is
continuously aligned with the path tangent of the leading axes.
