TIM101 Piezo Motor Controller
Note. The following parameters are applicable only if 'Go to Position is selected in the
'Button Mode' field.
Top Button Position: The position to which the motor will move when the top button is
pressed. The position is entered in 'Steps, measured from the Zero position.
Bottom Button Position: The position to which the motor will move when the bottom
button is pressed.
Note. The motor can be zeroed by clicking the 'Zero' button on the gui panel, or by
pressing and holding both buttons on the hardware unit for 2 seconds. Doing this will
zero the position counter, and subsequent moves will be measured from the position
the motor was at when the counter was zeroed..
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
a function of slider deflection. Bidirectional control of motor moves is possible by
moving the slider in both directions.
The speed is entered as a step rate (drive pulses per second) in the Max Step Rate
parameter, in the range 1 to 2,000.
Persist Settings to Hardware
Many of the parameters that can be set for the Piezo Driver T-Cube can be stored
(persisted) within the unit itself, such that when the unit is next powered up these
settings are applied automatically. This is particularly important when the driver is
being used manually in the absence of a PC and USB link. The potentiometer, button
and LED parameters described above are good examples of settings that can be
altered and then persisted in the driver for use in absence of a PC. To save the
settings to hardware, check the 'Persist Settings to Hardware' checkbox before
clicking the 'OK button.
Caution
The 'Persist Settings' functionality is provided to simplify use of the unit
in the absence of a PC. When the unit is connected to a PC and is
operated via APTUser, the default APTServer settings will be loaded at
boot up, even if the 'Persist Settings' option has been checked.
