MACHINE PARAMETERS.
(REF: 1402)
General machine parameters.
Requirements of the gantry axes.
Each pair of axes (master and slave) must meet the following requirements:
• The master axis must be defined in the AXISNAME table before the slave axis. Both axes
must belong to the same channel. The first three axes of the channel cannot be slaves.
• Both axes and drives must be of the same type (same AXISTYPE and DRIVETYPE
parameters for both axes).
• The channel changing permission (parameter AXISEXCH) must be the same in both
axes.
• Both axes and drives must have the same software limits (same LIMIT+ and LIMIT-
parameters for both axes).
• When the axes are rotary, both axes must be of the same type (same AXISMODE and
SHORTESTWAY parameters for both axes). Rotary axes that only turn in one direction
(parameter UNIDIR = YES) cannot be gantry.
• Hirth axes (HIRTH = YES) cannot be gantry axes.
• The I0 type (parameter I0TYPE) must be the same for both axes either non-distance-
coded or distance-coded (increasing or decreasing).
• When the gantry axis does not have distance-coded reference marks (I0), either both
axes or just the master axis may have a home switch ( parameter DECINPUT). The fast
and slow home search speeds (parameters REFFEED1 and REFFEED2) must be the
same for both axes.
• If cross compensation is active and the axis to be compensated is gantry, 2 compensation
tables must be included, one for the master axis of the gantry and another one for the
slave axis.
GANTRY n
Configuration of the gantry axes.
This parameter shows the parameter table to define the gantry axes of the system. Each
gantry axis has the following machine parameters to configure it.
MASTERAXIS
Gantry axis Master or main axis,
Possible values: Any axes defined in AXISNAME.
Associated variable: (V.)MPG.MASTERAXIS[nb]
Parameter included in the GANTRY table.
This parameter sets which is the master axis of the gantry pair.
SLAVEAXIS
Gantry axis. Slave axis.
Possible values: Any axes defined in AXISNAME.
Associated variable: (V.)MPG.SLAVEAXIS[nb]
Parameter included in the GANTRY table.
This parameter sets which is the slave axis of the gantry pair.
GANTRY
MASTERAXIS Gantry axis. Master or main axis,
SLAVEAXIS Gantry axis. Slave axis.
WARNCOUPE Gantry axis. Difference between the following errors of both
axes for issuing a warning.
MAXCOUPE Gantry axis. Difference between the following errors of both
axes for issuing a warning.
DIFFCOMP Gantry axis. Compensate for the coordinate (position)
difference between the two axes after G74.
MAXDIFF Gantry axis. Maximum position value (coordinate)
difference between both axes to compensate for.
