Ctrl Command move_to
Function moves the focusing optic of a varioSCAN
Call
move_to( Pos )
Parameter
Pos
Comments • It's only practical to use this command if a varioSCAN

• Rough position values for several working distances are listed in the varioSCAN
manual. The varioSCAN
position value.
• The first time the move_to command is called after
Pos = 0, the varioSCAN
reference position. In doing so, the varioSCAN
the step motor directly nearby. This position then serves as the null point. If an error
occurs during the reference motion, then the
to RTC5_PARAM_ERROR and positioning to Pos > 0 won't be performed.
• For Pos > 0, the varioSCAN
because the end stop is reached), then the
RTC5_PARAM_ERROR. In this case, you should check the varioSCAN
stops, stepper motor, etc.) for proper functioning and call move_to(0) for another
reference movement, followed by another call of the normal command move_to(Pos).
• If the RTC
header, then only a subset of the respective signals will be usable:
– Bits #12–15 of the 16-bit digital output are used for controlling the varioSCAN
To ensure that these four bits are set only via the move_to command (and not mis-
takenly via I/O commands, see below), they will be reserved exclusively for
varioSCAN
ity remains in effect until the next
move_to command executes, the four bits are still available but won't influence
varioSCAN
RTC
– Even when using the move_to command, you can continue altering the lower (but
not the upper) 8 bits of the16-bit digital output (without LATCH synchronization) for
other purposes via the commands write_io_port_list, write_io_port,
write_io_port_mask_list, write_io_port_mask, set_io_cond_list,
clear_io_cond_list
– Also available (via the RTC
upper) 8 bits of the 16-bit digital input (without SYNC synchronization) and the
BUSY-OUT signal.
