11.4.1 Configuration of a multi-axis group. Machine parameters.
Configuring a multi-axis group.
Multi-axis groups are configured via machine parameters. Each multi-axis group has the
following general machine parameters to configure it.
Defining the multi-axis groups of the system.
Parameter MULTIAXIS shows the multi-axis group definition table for defining the number
of groups of the system and the composition of each group.
Parameter MULNGROUP sets the number of multi-axis groups of the system. The table
shows a GROUP_n parameter for each multi-axis group.
Defining the axes or spindles that make up the multi-axis group.
Parameter MULNAXIS sets the number of axes and/or spindles making up the multi-axis
group. Since each axis or spindle of the CNC can have several parameter sets, the number
of axes of the group is limited by the 8 parameter sets available at the drive. The parameter
sets of the drive are distributed among all the axes and/or spindles that make up the multi-
axis group, so a group may be formed by 8 axes with 1 parameter set for each, 1 spindle
with 4 sets plus 2 axes with 2 sets each, etc.
The table shows a MUMLAXISNAME_n parameter for each axis or spindle that belong to
the multi-axis group. Any Sercos axis of the system may be part of a group, except those
that belong to gantry or tandem axes. The first axis of the group will be the master axis, the
one the drive will use by default; the order of the rest of the axes is irrelevant. On system
power-up, the CNC will use the parameters of the master axis to run the parameter matching
with the drive.
Setting the drive to be used.
At the axes that belong to a multi-axis group, parameter DRIVESET indicates the set to be
activated at the drive after a set or gear change at the CNC (G112 and M41 to M44). The
CNC sends the changes of Kv, feed-forward (parameter FFGAIN) and AC-forward
(parameter ACFGAIN) to the set indicated in this parameter.
Being parameter matching active, the CNC sends the parameters of set ·1· of the master
axis to the set ·0· and to the gear ·1· (first) of the drive. For the rest of the sets of the master
axis, the CNC only sends the gear data to the drive; set ·2· of the CNC to the gear 2 of the
drive and so on. At the master axis of multi-axis group, in order for parameter matching to
work properly, this parameter must coincide with the set number where it is; i.e. DRIVESET=1
in set ·1·, DRIVESET=2 in ·2· and so on. At the slave axis of a multi-axis group, this parameter
indicates the gear to be used at the drive. If the axis belongs to a multi-axis group, the
parameter does not admit a ·0· (zero) value.
