Response Description
Reports value of O allowing for joystick speed buttons effect (if the button
s
speed is ½ and O is set to 50 the returned value will be 25)
Reports absolute position of x,y and z axes. This can be used whilst any axis
x,y,z is moving to give 'position on the fly' Note <CR> only will also return
position.
Sets absolute position of x, y, and z axis. No axis can be moving for this
0
command to work
x Reports position of x only.
Sets Absolute position of x axis. No axis can be moving for this command to
0
work.
y Reports position of y only.
Sets Absolute position of y axis. No axis can be moving for this command to
0
work.
R Moves Right by u steps as defined by 'X' command.
R Moves Right by x steps.
Sets the user unit step size in microsteps for the stage. By default this value is
0 the number of microsteps/micron as detailed in the STAGE command. This
value is linked with RES,S and XD/YD values
Returns the current number of microsteps per user unit.
s NOTE: in COMPATABILITY mode this value is based on the older 100
microsteps/fullstep of H127/128 systems!
Sets the desired resolution for the stage, s is X and Y axes, r can be a non
integer number setting the resolution for the axis in units of microns.
e.g.
RES,S,1.0
Resolution set to 1.0 micron
Not all resolutions are achievable accurately. Only those that are direct
multiples of the base microstep resolution. See Appendix B and SS
commands.
Returns resolution for axis a.
Restore Index of Stage. This command is only effective if the SIS command
has been used on installation. This Command can be used at any time and
will re synchronise the stage and controller position should the stage have
R been manually moved when the controller was off. The stage will hit limits
and then return to the position stored by the controller prior to the last
power down. If the stage has not been manually moved this command will
not normally be needed.
Sets the maximum stage acceleration to a. 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.
a Report current stage acceleration
n=number of intrinsic units/s/s the stage current stage acceleration is set to.
n Intrinsic units would be microsteps for stepper stages and encoder counts
for linear stages.
0 Sets the current stage acceleration to n intrinsic units/s/s
n n=number microns per second the stage current stage acceleration is set to.
0 Sets the current stage acceleration to n microns per second.
Sets the current stage S-curve value. This is the rate of change of
acceleration during the transition from stationary until the stage reaches the
0 full acceleration set by SAS. Range of c is 1 to 1000.
Prior chooses to express curve in time units rather than units/s/s/s. So at
default 100 setting curve time = 13ms. At 200 curve time = 6.5ms
