Machine parameters for the axes and spindles.
TYPLSCRW
Type of compensation (type of coordinates).
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: Real / Theoretical.
Default value: Real.
Associated variable: (V.)[ch].MPA.TYPLSCRW.xn
Parameter included in the LSCRWCOMP table.
This parameter determines whether the leadscrew error compensation will be applied on to
theoretical or real coordinates.
BIDIR
Bi-directional compensation.
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.BIDIR.xn
Parameter included in the LSCRWCOMP table.
This parameter indicates whether the compensation is bidirectional or not; i.e. if the
compensation is different in each direction. If the compensation is not bidirectional, it applies
the same compensation in both directions.
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).
LSCRWCOMP
DATA
POSITION Axis position.
POSERROR Amount of error to compensate when moving in the positive
direction.
NEGERROR Amount of error to compensate when moving in the negative
direction.
