too large. MOST USERS DO NOT NEED TO USE THIS FUNCTION! It’s an
Axis-Specific
Command.
Command: LCD
(not supported in TG-1000)
Command: LED
(PWM_LED_DIM Firmware Required)
Format:
[Addr#]LED [X=0 to 100]
Function:
Sets the brightness of ASIs LED illuminator by generating PWM thru TTL out. TTL out
mode should be set to ‘9’ (i.e.
TTL y=9
). Enable out from the LED illuminator should
be connected to TTL out on controller. This setting can be saved in non-volatile memory
using the
SAVESET
command. The PWM frequency is 1.3KHz. It’s a
Card-Addressed
command.
NOTE:
If you are encountering flickering, try adjusting your shutter speed to integer multiples
of the PWM period (0.77 ms).
Command: LLADR
Shortcut:
LL
Format:
LLADR [Axis]=### …
Function:
Sets the address of the axis used by the low-level command set. The default values are
X=24
,
Y=25
, and
Z=26
. Some systems require
X=1
,
Y=2
, and
Z=3
. This setting can be
saved in non-volatile memory using the
SAVESET
command. It’s an
Axis-Specific
Command.
Command: LOAD
(RING BUFFER Firmware Module Required)
Shortcut:
LD
Format:
LOAD [Axis]=### …
Function:
The
LOAD
function places a set of position coordinates in the next available internal
ring-buffer memory location. The position values are expressed as floating point
numbers representing tenths of a micron, the same as the MOVE command. If a
+
is
specified instead of
=###
, then the current position of the axis is stored in the ring
buffer (as of firmware v2.81). For example, the command
LOAD X+ Y+ Z=0.1
would store the current position of the X and Y axes and the Z position of 10nm to the
ring buffer. The ring buffer contains 50 positions by default; contact ASI for the option
of having 250 positions in the ring buffer (but this entails certain tradeoffs). The
