K-Cube Piezo Driver
Trig In Jog Down
-
Only applicable in Open Loop mode.
Input trigger for
absolute move. On receipt of the trigger, the drive voltage decreases by the value
set in the
Wheel Step Size
parameter.
When the
Trig 1 Mode
and
Trig 2 Mode
parameters are configured as outputs, the
TRIG ports can be used as a general purpose digital output as follows:
Digital Output
- Gen eral purpose logic output (set using the LLSetGetDigOPs
method).
Triggering Polarity
The polarity of the trigger pulse is specified in the
Trig. 1 Polarity
and
Trig 2 Polarity
parameters as follows:
Active is High
- The active state of the trigger port is logic HIGH 5V (trigger input
and output on a rising edge).
Active is Low
- The active state of the trigge r port is logic LOW 0V (trigger input
and output on a falling edge).
Disp. Brightness
In certain applications, it may be necessary to adjust the brightness of the LED display on the
top of the unit. The brightness is set in the
Active Level
parameter, as a value from 0 (Off) to
100 (brightest). The display can be turned off completely by entering a setting of zero, however,
pressing the MENU button on the top panel will temporarily illuminate the display at its lowest
brightness setting to allow adjustments. When the display returns to its default position display
mode, it will turn off again.
Furthermore, 'Burn In' of the display can occur if it remains static for a long time. To prevent
this, the display is automatically dimmed after the time interval specified in the
Timeout (min)
parameter has elapsed. The time interval is specified in minutes in the range 0 (never dimmed)
to 480. The dim level is set in the
Idle Level
parameter, as a value from 0 (Off) to 10 (brightest)
but is also limited by the
Active Value
parameter if this is lower.
Persist Settings to Hardware -
Many of the pa rameters that can be set for the DC
Driver K-Cube can be stored (persisted) within the unit itself, such that when the unit
is next powered up th ese 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 wheel, and trigger parameters described here 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.
