6.12. Buffered Interpolation Moves
PMX-4EX-SA supports buffered linear coordinated motion for X, Y, and Z-axes
using the
I
command. This allows for the contouring of unique patterns without
any delay between multiple moves. Each move has its own constant speed
setting.
The buffer for the linear interpolation buffer mode contains 36 separate position
points. To turn on and off buffer move, use the
BO
and
BF
ASCII command
respectively. For standalone mode, the
BUFON
and
BUFOFF
commands
should be used. When enabled, motion will start as soon as the first buffered
move command is issued. The buffered move operation cannot be used while
StepNLoop is enabled.
The motor status of the PMX-4EX-SA contains the status of the buffer operation.
See section 6.15 for more information on this.
In ASCII mode, a buffered move command will have the syntax
I[X pos]:[Y
pos]:[Z pos]:[speed]
. For example, to enter the position (1000,2000,3000) at a
speed of 5000 into the buffer, the
I1000:2000:3000:5000
command should be
used. If buffered mode is note enabled,
I
commands will not be processed by the
controller.
In standalone mode, the buffered move command will have the syntax
X[pos]Y[pos]Z[pos]
and the speed for the move command will use the current
global high speed setting. If buffered mode is not enabled, these standalone
commands will be process as regular linear interpolation commands.
Circular and arc interpolation moves can also be added to the buffer. The
ARC
and
CIR
commands, described in section 6.10 and 6.11, can be used when
buffer mode is enabled. The syntax for these commands will stay the same in
ASCII and standalone mode.
The buffered interpolation feature includes an automatic acceleration option. The
IACC
command is used to control this feature. When
IACC=0
, acceleration and
deceleration must be done manually. To control the acceleration or deceleration
manually, gradually increase or decrease the speed value for each interpolated
move.
When
IACC=1
, acceleration and deceleration are processed automatically. In
this case, the speed acceleration profile will be automatically generated between
sequential buffered moves. The acceleration/deceleration value used for
automatic acceleration control is found in the global acceleration value (
ACC
).
