/i
Description
The
BASE
command is used to set the default base axis or to set a specified
axis sequence group. All subsequent motion commands and axis parameters
will apply to the base axis or the specified axis group unless the
AXIS
com-
mand is used to specify a temporary base axis. The base axis is effective until
it is changed again with
BASE
.
Each BASIC process can have its own axis group and each program can set
its own axis group independently. Use the
PROC
modifier to access the
parameter for a certain task.
The
BASE
order grouping can be set by explicitly assigning the order of axes.
This order is used for interpolation purposes in multi-axes linear and circular
moves. The default for the base axis group is
(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) at start-up or when a program starts
running on a task. The
BASE
command without any arguments returns the
current base order grouping.
Note: If the
BASE
command does not specify all the axes, the
BASE
com-
mand will “fill in” the remaining values automatically. Firstly it will fill in any
remaining axes above the last declared value, then it will fill in any remaining
axes in sequence.
So
BASE(2,6,10) will set the internal array of 16 axes to:
2,6,10,11,12,13,14,15,0,1,3,4,5,7,8,9.
Arguments
The command can take up to 16 arguments.
•
axis_i
The number of the axis set as the base axis and any subsequent axes in
the group order for multi-axis moves.
Example
BASE(1)
UNITS = 2000 ' Set unit conversion factor for axis 1
SPEED = 100 ' Set speed for axis 1
ACCEL = 5000 ' Set acceleration rate for axis 1
BASE(2)
UNITS = 2000 ' Set unit conversion factor for axis 2
SPEED = 125 ' Set speed for axis 2
ACCEL = 10000 ' Set acceleration rate for axis 2
It is possible to program each axis with its own speed, acceleration and other
parameters.
Example
BASE(0)
MOVE(100,-23.1,1250)
In this example, axes 0, 1 and 2 will move to the specified positions at the
speed and acceleration set for axis 0.
BASE(0)
sets the base axis to axis 0,
which determines the three axes used by
MOVE
and the speed and accelera-
tion rate.
Example
>> BASE(0,2,1)
On the command line the base group order can be shown by typing
BASE
.
Example
>> RUN "PROGRAM",3
>> BASE PROC(3)(0,2,1)
Use the
PROC
modifier to show the base group order of a certain task.
Example
>> BASE(2)
>> PRINT BASE
2.0000
Printing
BASE
will return the current selected base axis.

Syntax
BASICERROR
Description
The
BASICERROR
command can be used to run a routine when a run-time
error occurs in a program.
BASICERROR
can only be used as part of an
ON
... GOSUB
or
ON ... GOTO
command. This command is required to be exe-
cuted once in the BASIC program. If several commands are used only the
one executed last is effective.
