Response Description
c Report current stage S-curve setting.
Set Index of Stage. This command would normally only be used on first
installation of the system. The stage moves to limits and sets absolute
R
position to 0,0. The controller will always remember this internally as zero
even with subsequent uses of Z and P, x , y command.
Sets the current Stage (x, y) maximum speed to m. Range is 1 to 1000.
Default setting is 100 and used by Prior during long life testing. Higher values
0
are allowed but their efficacy is constrained by varying factors such as stage
type, users stage payload motor type etc.
m Report the current Stage (x, y) maximum speed setting m
n=number of intrinsic units per second the stage current stage speed is set
n to. Intrinsic units would be microsteps for stepper stages and encoder counts
for linear stages.
Sets the current stage speed to n. n is the number of intrinsic units per
0
second.
n n=number microns per second the stage current stage speed is set to.
0 Sets the current stage speed to n. microns per second.
Prints information about the currently connected stage. The final line of
information is always a line saying END. This allows for the addition of extra
fields of information without effecting application software. Users should
always read lines in until the END is seen.
Example
STAGE = H101/2
TYPE = 1
SIZE_X = 108 MM
SIZE_Y = 71 MM
Text string
MICROSTEPS/MICRON = 25
LIMITS = NORMALLY CLOSED
END
The sizes are approximate based on the original stage designate and are
variable as limit switches can be mechanically adjusted by users. Prior
recommendation is to measure the stage from software by moving between
back and left and front right limits and calculating the travel from the
returned XY positions.
Returns the skew angle a, in degrees, that had previously been set by the
a
SKEW,A and SKEW,S commands or the SKEW,A command.
Sets the direction of the X axis move (mechanical) with respect to the
0 software move. Use this command if 'L' command moves stage mechanically
right. d=1 or –1.
Sets the direction of the Y axis move (mechanical) with respect to the
0 software move. Use this command if 'F' command moves the stage
mechanically backwards. d=1 or –1.
0 Sets the stage and focus position to ZERO (0,0,0).
Turn the given axis a to motor state b.
E.g.
MOTOR, X, 1 turns X motor on.
MOTOR, 2, 1=0 turns Y motor off.
Axes are identified by their number or character:
0
NOTE: for stepper stages, turning motors off then on may result in a small
position error
