11
step size according to the encoder resolution. The current value for this setting can be
viewed using the
INFO
command. It’s an Axis-Specific Command.
Example:
PC X=.00005 Y=.00002 Z=.00005
:A
Values equal to or less than zero are acknowledged by "
:A
", but ignored.
The command in this example will make the controller consider a
MOVE
command
complete when the difference between the target and the current position is 50 nm for
X, 20 nm for Y, and 50 nm for Z.
Warning: If the
PCDOS
value is extremely small, moves
may take an excessively long time to complete.
Command: MULTIMV

: [Addr#]MM [X=radius] [Y= speed] [Z= width] [F=mode]

Function: The
MULTIMV
command allows several common multi-axis move patterns to be
executed. Presently the patterns supported include circles and spirals. If users have
other special requirements, they should contact ASI for assistance.
The command, without any arguments, initiates the multi-axis pattern move.
The patterns are initiated from the current stage position. The movement is
parameterized in terms of the speed (feed rate) in mm/sec and pattern parameters. For
circles, the radius in millimeters is the only required parameter. For spirals the width
per spiral turn in millimeters is required as well as the maximum radius.
The mode is a bit-mapped character that determines the characteristics of the motion.
The mode bits are used according to the following table.
Bit Set Clear
0 Lead-in Move Used No Lead-in Move
1 Controlled acceleration along path, set by ACCEL
command, to programmed speed.
No controlled acceleration
2 Move pattern repeated indefinitely Only single cycle of move pattern
executed
