Digital positioner setup
The Digital positioner screen contains fields for calibrat-
ing and configuring digital positioner motion.
Enabling digital positioner mo-
tion
Check an axis Enable box to enable digital positioner
motion, or clear the box to
disable digital positioner
motion on that axis.
Reversed axis direction
The direction of motion controlled by the digital positioner on an
axis is reversed to accommodate different digital positioner and sys-
tem hardware by checking the Reversed
axis box.
Normal and fine axis velocity
The normal and fine axis velocities controlled by the digital positioner are specified by selecting a Normal
or Fine velocity field and entering the desired percentage of maximum axis velocity. Normal and fine
speed control is assigned to a joystick button in the Buttons setup screen.
Acceleration (Accel%)
The axis acceleration controlled by the digital positioner is specified by selecting an axis field and entering
the desired percentage of maximum axis acceleration.
Debounce counts
An area of digital positioner inactivity is specified around the current rest position of each axis to eliminate
erroneous axis motion due to digital positioner vibration or noise. The default values are expressed as
positioner counts and will satisfy the requirements of most environments, however these values can be
increased or decreased by selecting the Debounce Cnts field and entering
the desired value.
