Jog
- used to increment or decrement the motor position. When the button is clicked,
the motor is driven in the selected direction at the jog velocity one step per click. The
step size and jog velocity parameters are set in the 'Settings' panel (see Section 5.3.).
Travel
- the travel (in mm or degs) of the actuator associated with the GUI panel.
Digital display
- shows the position (in millimetres or degrees) of the motor. The
motor must be 'Homed' before the display will show a valid position value, (i.e. the
displayed position is relative to a physical datum, the limit switch).
Home/Zero
- sends the motor to its 'Home' position. The LED in the button is lit while
the motor is homing.
Homed
- lit when the motor has previously been 'Homed' (since power up).
Moving
- lit when the motor is in motion.
Stop
- halts the movement of the motor.
Enable
- applies power to the motor. With the motor enabled, the associated Channel
LED on the front panel is lit.
Position Error
- lit when the associated axis has exceeded the position error limit
setting - see Section 5.3.3.
Current Limit
- lit when an ‘current foldback’ condition exists - Section 5.3.4.
Limit switches
- the LEDs are lit when the associated limit switch has been activated
Settings display
- shows the following user specified settings:
Driver -
the type of control unit associated with the specified channel.
Stage
- the stage type and axis associated with the specified channel.
Calib File
- the calibration file associated with the specified channel.
Min/Max V
- the minimum velocity at which a move is initiated, and the maximum
velocity at which the move is performed. Values are displayed in real world units
(mm/s or degrees/s), and can be set via the 'Settings' panel (see Section 5.3.).
Accn
- the rate at which the velocity climbs to, and slows from, maximum velocity,
displayed in real world units (mm/s/s or degs/s/s). The acceleration can be set via
the 'Settings' panel (see Section 5.3.) and is used in conjunction with the Min/Max
velocity settings to determine the velocity profile of a motor move.
Jog Step Size
- the size of step (mm or degs) taken when the jog signal is initiated. The
step size can be set either via the Settings panel or by calling the SetJogStepSize method.
Settings button
- Displays the 'Settings' panel, which allows the motor drive’s
operating parameters to be entered - see Section 5.3.
Note
The software automatically associates the stage/actuator type on bootup.
Note
Calibration files are not applicable for the Thorlabs Brushless DC motor
stages such as the MLS203.
