POSA CURVEPOS
Summary Move slave to the curve position corresponding to the master position
Syntax POSA CURVEPOS
Description 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 .
Command Group ABS, CAM
Cross Index CURVEPOS, SET ORIGIN
Syntax Example POSA CURVEPOS
// Move slave to the curve position corresponding to the master position
Sample Fix points of a curve:
Master Slave
0
500
700
1000 0
500
300
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.

POSR
Summary Positioning in relation to actual position
Syntax POSR d
Parameter d = distance to actual position in user units (UU); this corresponds in the standard
setting to the number of Quadcounts.
Description 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 .
Command Group REL
Cross Index VEL, ACC, POSA,
Parameters: 32-12 User Unit Numerator , 32-11 User Unit Denominator
Syntax Example POSR 50000 /* move axis relative 50000 UU */
