REFNEED
Mandatory home search.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Yes / No.
Default value: No.
Associated variable: (V.)[ch].MPA.REFNEED.xn
Parameter included in the LSCRWCOMP table.
This parameter indicates whether the axis must be homed or not before applying the
compensation.
DATA
Leadscrew error compensation at each point.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
This parameter shows the list of compensation points and values. The CNC only lets access
this table when parameter NPOINTS has been set.
The DATA table must indicate the amount of error to be compensated in specific positions
of the axis. The number of points is set by parameter NPOINTS. Parameters POSITION,
POSERROR and NEGERROR must be set for each point. Parameter NEGERROR only if
the table has been defined with bidirectional compensation (BIDIR = YES).
POSITION
Position of each point.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values (1): Within ±99999.9999 mm.
Possible values (2): Within ±3937.00787 inch.
Possible values (3): Within ±99999.9999 degrees.
Default value: 0.
Associated variable: (V.)[ch].MPA.POSITION[pt].xn
Parameter included in the LSCRWCOMP // DATA table.
Each parameter of the table represents a profile point to be compensated. The position that
occupies the point in the profile will be referred to machine zero. When defining the various
points in the table, the following requirements must be met.
• The points of the table must be ordered by their position on the axis and the table must
begin by the most negative point (or least positive) to be compensated. For axis
positioning outside this area, the CNC will apply the compensation that was defined for
the nearest end.
• The maximum slope of the table is ·1·; i.e. the compensation steps must not exceed the
position step between two consecutive points.
Import leadscrew compensation tables.
In order to save time and eliminate transcription errors, instead of entering the data manually,
it is possible to adapt the format of a text file that contains the result of the measurement
and import it later on.
