Indicator LED Modes
A single LED is fitted to the front panel of the unit. This LED can be configured to
indicate certain driver states as follows:
Limit Switch Activation: When this option is selected, the LED will flash when the
motor reaches a forward or reverse limit switch.
Ident: When this option is selected, the LED will flash when the ‘Ident’ button is clicked
on the APT Software GUI panel.
Motor Moving: When this option is selected, the LED is lit when the motor is moving.
It is recognised that, in a light sensitive environment stray light from the LED could be
undesirable. Therefore it is possible to disable selectively, one or all of the LED
indicator modes described above by clearing the associated check boxes in the ‘LED
Indicator Modes’ field.
Potentiometer Control Settings
The potentiometer slider is sprung such that when released it returns to it’s central
position. In this central position the motor is stationary. As the slider is moved away
from the center, the motor begins to move; the speed of this movement increases as
the slider deflection is increased. Bidirectional control of motor moves is possible by
moving the slider in both directions. The speed of the motor increases by discrete
amounts rather than continuously, as a function of slider deflection. These speed
settings can be altered via the ‘Potentiometer Control Settings’ parameters.
There are 4 pairs of parameters, each pair specifies a pot deflection value (in the
range 0 to 127) together with an associated velocity (set in real world units, mm or
degrees) to apply at or beyond that deflection. As each successive deflection is
