Move slave to the curve position corresponding to the master position
POSA CURVEPOS
This command acts like POSA and moves the slave to the corresponding position on
the curve, which is given by the actual master position.
NB!:
If a temporary zero point, set via SET ORIGIN, exists and is active, then the
position result refers to this zero point.
NB!:
If an acceleration and/or velocity have not been defined at the time of the POSA
command, then the procedure will take place with the values of parameters 32-84
Default Velocity and 32-85 Default Acceleration.

POSA CURVEPOS
// Move slave to the curve position corresponding to the master position
Fix points of a curve:
Master Slave
0 0
500 500
700 300
1000 1200
Say the current master
position is 800 (the
darkened vertical line).
Case 1: Current Master Position is 800 and current slave position is 200.
POSA CURVEPOS will move the slave to 450.
Case 2: Current Master Position is 800 and current slave position is 700.
POSA CURVEPOS will move the slave to 450.
Positioning in relation to actual position
POSR d
d = distance to actual position in user units (UU); this corresponds in the standard
setting to the number of Quadcounts.
The axis can be moved to a position relative to the actual position by use of the
POSR command.
NB!:
If acceleration and/or velocity has not been defined at the time of the POSR
command, then the procedure will take place with the values of parameters 32-84
Default Velocity and 32-85 Default Acceleration.
