Concepts & Terminology:
Auto-Retract:
Pressing and holding the zero button for approximately three seconds will initiate the auto-retract function. Once initiated,
the controller will retract the motor at top speed to the origin point. If an initial offset has been specified, this is where the drive will stop.
Initiating the auto-retract function while at the initial offset origin will cause the drive to retract to the zero point. Pressing any control
during the auto-retract cycle will immediately cancel the auto-retract cycle.
Display Mode:
The controller can be configured to display the current depth value in distance from zero mode where it will always match
the reading obtained from the scale of the drive or in distance from target mode where the target depth will be the zero point with positive
depth values below target and negative values above.
Display Units:
The controller can be configured to display the current depth in microns (XXXXXµm) or in millimeters (XX.XXmm) according
to user preferences.
Drive:
The micropositioner, this should be either a microTargeting™ Drive or a STar™ Drive.
Initial Offset:
When desired, the origin point used while zeroing the drive need not be the 0 mm mark of the drive. If desired, an initial
offset value can be entered through the USB interface to begin the procedure at a depth other than zero. For instance, if an initial offset of
15mm is entered, to zero the drive – one would position it at the 15mm mark and press the zero button. The initial offset value will reset to
0mm every time the controller is powered down.
Language Support:
The controller is capable of displaying all front panel information in numerous languages. The language setting is
changed through the USB interface. Supported languages include: English, French, German, Italian, Spanish, Danish, and Swedish (others
may be added in later updates).
Limit:
A depth limit value that can be entered through the USB interface. The controller will not allow the drive to be advanced beyond
this point. The limit value will be retained when the controller is powered down and is set to 50mm by default. Note that both the
microTargeting™ Drive and the STar™ Drive provide a physical stop at approximately 55mm.
Querying Settings:
The current settings for initial offset, target and limit depths will be displayed by the controller when the zero button is
pressed any time after zeroing the drive.
Speeds:
There are four speed options available, they can be set from 1 micron per second up to 500 microns per second. The default drive
speeds are set to: 10, 50, 225 and 500 µm/s. These can be adjusted through the USB interface according to preferences. To select a speed,
simply adjust the speed slider switch on the remote control. The first speed position of the slider switch is always STOP (or 0 microns per
second) and will prevent the controller from moving.
Stop Points:
The controller can automatically stop advancing periodically to facilitate MER, once every mm for instance. Through the USB
interface, one sets a step size then presses and holds the Advance rocker switch on the hand held remote control. The controller will
automatically stop advancing once the step size distance has been traveled. To advance to the next stop point, one releases the advance
button and re-engages it. Alternately, one can issue a GO command through the USB interface to resume advancing.
Target:
The depth at which the target is expected to be reached can be set to any value between the initial offset and the limit values.
The target value will be retained when the controller is powered down and is set to 30mm by default.
USB Interface:
The controller’s USB interface emulates a serial (COM) port. When first plugged into a PC, the driver for the controller will
be installed and a virtual COM port will appear. To establish communications with the controller, a terminal emulator application will need
to be installed and run on the PC (such as Window’s HyperTerminal). Baud rate should be set to 19200 bps, 8 bit words. See the reference
information section for a description of commands supported.
User Profiles:
The controller can save and store up to 5 different user profiles to allow users to easily configure the controller according to
different user’s speed preferences and/or optimized settings for different types of procedures. A user profile contains all available speed
settings. Profiles are loaded and saved through the USB interface.
Zeroing the Drive:
Mounting the motor unit onto the drive and using the hand held remote control to adjust the drive depth to the
origin. Once the drive is positioned at the origin, press the zero button on the hand held remote control and the depth of the drive will
be tracked by the controller for the remainder of the procedure.
