Detailed description
2.4 Actions in synchronized actions
TRAILON - Coupled motion from a synchronized action
From a synchronized action it is possible to define and simultaneously activate the
assignment of a following axis to a leading axis using a coupling factor:
... DO TRAILON(FA, LA, Kf)
where:
FA
LA
Kf
The commands for separating the coupled-axis grouping are as follows:
... DO TRAILOF(FA, LA, LA2)
... DO TRAILOF(FA)
where:
FA
LA
LA2
Curve tables
The relationship between a master quantity and a slave quantity stored in curve tables can
be utilized in synchronized actions in the same way as other REAL functions (e.g. SIN,
COS).
Calculate slave value
The slave value calculated from a master value on the basis of curve table n must be
assigned to an arithmetic variable.
Example
... DO $R17=CTAB(LW, n, degree)
where:
LW
n
degrees
Example
DEF REAL GRADIENT
...
WHEN $A_IN[1] == 1 DO $R17 = CTAB(75.0, 2, GRADIENT)
