using the ‘Settings’ button (bottom right hand corner of the GUI) and subsequently
displayed in the 'Settings' panel.
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 6.3.).
Travel - displays the range of travel (in millimeters or degrees) of the motor.
Moving - lit when the motor is in motion.
Enable - applies power to the motor. With the motor enabled, the LED in the button
is lit.
Note. To position a motor manually, (e.g. via a knob on the shaft) it should first be
disabled (de-energised). After manual positioning is complete, remember to enable
(re-energise) the motor so that it can be moved via the software.
Digital display - shows the position (in millimetres or degrees) of the motor. The
motor must be 'Homed' before the display will show a meaningful value, (i.e. the
displayed position is relative to a physical datum, the limit switch).
Home - sends the motor to its 'Home' position - see Appendix D Section D.2.2. The
LED in the button is lit while the motor is homing.
Homed - lit when the motor has previously been 'Homed' (since power up).
Stop - halts the movement of the motor.
Limit switches - the LEDs are lit when the associated limit switch has been activated
- see Appendix D Section D.2.3. for further details on limit switches.
Settings display - shows the following user specified settings:
Stage - the stage type and axis associated with the specified channel.
Calib File - the calibration file associated with the specified channel.
See the APTConfig utility helpfile for more details on assigning and using calibration
files.
Backlash Dist - the backlash distance in mm or degrees. The backlash can be set via
the 'Settings' panel (see Section 6.3.).
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 6.3.).
Accn - the rate at which the velocity climbs to, and slows from, maximum velocity,
displayed in real world units (mm/s/s or degrees/s/s). The acceleration can be set via
the 'Settings' panel (see Section 6.3.) and is used in conjunction with the Min/Max
velocity settings to determine the velocity profile of a motor move. See Appendix D
Section D.1.3. for more information on velocity profiles.
Jog Step Size - the size of step (in mm or degrees) 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 6.3. Note. The channel settings
