4.2.2
Digital Display - Operating Mode
During normal operation, the digital display shows the current position (in millimeters
or degrees) and the current state of the motor (Stopped or Moving). If the stage being
driven has been homed, the display will also show ‘Homed’.
Fig. 4.2 Digital Display - Normal Operation
For rotation stages, the position display will be restricted to the "Equivalent Angle"
display mode (see Section 6.3.6. for more details), so the position displayed will
always be a positive number between 0 and 360 degrees. If set to Total Angle in the
settings panel, the LED display will still show the equivalent 0 to 360° value but the
GUI screen will show the total rotation.
4.3
Velocity Wheel Operation
The velocity wheel is a sprung potentiometer, such that when released it returns to its
central position. In this central position the motor is stationary. Different types of move
can be initiated by the wheel, depending on its mode setting. The mode can be set
either via the GUI Settings panel, see Section 6.3.4. or via the top panel display menu,
see Section 4.4. The various operating modes are described in Section 4.3.1. to
Section 4.3.3.
4.3.1
Homing
A ‘Home’ move is performed to establish a datum from which subsequent absolute
position moves can be measured (see Section 5.3. and Section E.2.2. for further
information on the home position).
To initiate a ‘Home’ see Section 4.4.3.
4.3.2
Go to Position
In ‘Go To Position’ mode, two preset position values can be specified, such that the
motor moves to position 1 when the wheel is moved down, and to position 2 when it
is moved up. These ‘taught’ positions can be set through the software GUI - see
Section 6.3.4. or via the display menu, see Section 4.4.7.
