coordinates for the next move may be queried by using the command
LD X? Y?
Z?
. Setting the current buffer position and initiating moves to locations stored in the
buffer can be done using the
RBMODE
command (see below), or by using a front panel
button. The
LOAD
operation increments the
number-of-positions
counter accessed
using
RM X?
(see the
RBMODE
command). In TG-1000 the ring-buffer is stored and
executed on a per-card basis. If positions for one or more axes on one card are specified
but others are not, the position of the unspecified axes during the ring buffer execution
will not be well-defined. To clear the buffer, type
RM X=0
(see the
RBMODE
command). It’s an
Axis-Specific Command.
The current stage position (for all axes with RING_BUFFER firmware) may be loaded into
the ring-buffer by pressing the Joystick button for 3 seconds and releasing.
Command: LOCK
(For CRIFF and AF-DUAL Systems)
Shortcut:
LK
Format:
[
Addr#]LK [X] [Y] [Z] [F]
Function:
Without argument, advances to the next system state until the
Cal_OK
state is reached.
Once a good calibration is obtained, a subsequent
LK
command initiates the
Lock
state
in which the servo loop error signal is supplied from the focus system. For CRIFF the
lock is made at current location reference. (See
RELOCK
command.). It’s a
Card-
Addressed command.
LK X
returns the current system state code.
LK Y
returns current focus error signal.
LK Z
Unconditionally advances to the next system state.

Command: LOCKRG
(For CRIFF and AF-DUAL Systems)
Shortcut:
LR
Format:
[Addr#]LR [Z=lock_range]
Function:
The Z parameter of the LOCKRG command allows the user to control the maximum
excursion of the stage before the system generates an error condition and unlocks. The
value
lock_range
is in millimeters. The default value is 0.050mm. It’s a
Card-Addressed
command.
