Studies of the Newport XPS controller by Vanik
These studies were done using halldxps1 XPS-C8 controller from Newport.
Contents
1. Configuration of the XPS Controller
1.1 Configuration of motor and stage
Building of "stages.ini" file which is located in the "CONFIG" folder of the controller.
- Connect to the XPS Controller halldxps1 using an internet browser.
- Login as Administrator.
- Select STAGE, then "Add Custom Stage" and fill all fields.
I defined Stage1 (Stage_ST55D) Stage for the stepper motor ST55D and Stage for microscope beam test as follows:
[Stage1]
SmartStageName=
- Position servo loop type
CorrectorType=NoEncoderPosition
MotionDoneMode=Theoretical
- Driver command interface
MotorDriverInterface=AnalogStepperPosition
ScalingCurrent=3
DisplacementPerFullStep=1
PeakCurrentPerPhase=1.3
StandbyPeakCurrentPerPhase=0.6
BaseVelocity=0.
- Motor driver model
DriverName=XPS-DRV01
DriverPWMFrequency=50
DriverStepperWinding=Half
- Position encoder interface
Backlash=0 CurrentVelocityCutOffFrequency=100
CurrentAccelerationCutOffFrequency=100
PositionerMappingFileName=
- Limit sensors input plug
ServitudesType=StandardEORDriverPlug
MinimumTargetPosition=-10000000
MaximumTargetPosition=+10000000
HomePreset=0
MaximumVelocity=400
MaximumAcceleration=100
EmergencyDecelerationMultiplier=4
MinimumJerkTime=0.005
MaximumJerkTime=0.05
TrackingCutOffFrequency=5
- Home search process
HomeSearchSequenceType=MinusEndOfRunHomeSearch
HomeSearchMaximumVelocity=250
HomeSearchMaximumAcceleration=70
HomeSearchTimeOut=600.
1.2 Configuration of system and motion groups
Building of "sistem.ini" file which is located in the "CONFIG" folder of the controller.
- Select SYSTEM, then "Manual Configuration" and define motion groups and stages on them.
I defined one MultipleAxes group - Mult1 with Stage1 stage as follows:
[GENERAL]
BootScriptFileName =
BootScriptArguments =
[GROUPS]
SingleAxisInUse =
SpindleInUse =
XYInUse =
XYZInUse =
MultipleAxesInUse = Mult1
[Mult1]
PositionerNumber = 1
PositionerInUse = P1
InitializationAndHomeSearchSequence = Together
[Mult1.P1]
PlugNumber = 1
StageName = Stage1
- Time flasher filter
TimeFlasherBaseFrequency = 40e6 ; Hz
2. Testing of the XPS Controller by WEB interface
- Connect to the XPS Controller halldxps1 using an internet browser.
- Login as Administrator or User.
- Select FRONT PANEL, then "Move".
- Select Initialize button for the initialization of the positioner (motion system).
- Select Home for homing.
After fineding Home position the Controller and the Positioner are ready. Now one can select some velocity and number of Absolute or Relative movements and push to the Go button. In the "Position" field indicates positon of the stage during movement. Using the Jog button under the FRONT PANEL I tested the jog motion, where only motion direction and speed are defined.
The TERMINAL tool allows to execute all functions (more 100) of the XPS controller.
The STAGE - Modify tool allows to review and modify all parameters of stage included in the stages.ini file.
No any problem. Everything is working.
