Parameters
(cont’d)
PreviewTime
Precalculation time for galvanometer scanner control.
In 10 µs.
PreviewTime
is ignored in
Mode = 0
and
Mode = 1
.
As an unsigned 32-bit value.
Vmax
Velocity limit as control bits (galvanometer scanner rotation angle).
In bits/10 µs.
Vmax
is ignored in
Mode = 0
and
Mode = 1
.
As an unsigned 32-bit value.
Amax
Acceleration limit as control bits (galvanometer scanner rotation angle).
In bits/(10 µs)².
Amax
is ignored in
Mode = 0
and
Mode = 1
.
As a 64-bit IEEE floating point value.
Result Error code. As an unsigned 32-bit value.
Value Description
1 Option “SCANa“ is not present.
(get_last_error return code:
RTC6_REJECTED
).
3 No excelliSCAN scan head attached or excelliSCAN tuning is not active
(get_last_error return code:
RTC6_PARAM_ERROR
).
5 A list is currently active
(get_last_error return code:
RTC6_BUSY
).
6
HeadNo
=
0
and
HeadNo
>2
(get_last_error return code:
RTC6_PARAM_ERROR
).
7 The determined scaling factor exceeds 16 or is below 1/16 (possibly no
correction file was loaded). The scaling factor is set to 1.
8 The RTC6 board is not responding. Probably a program
has not been loaded yet
(get_last_error return code:
RTC6_TIMEOUT
).
11 A PCI error occurred
(get_last_error return code:
RTC6_SEND_ERROR
).
Comments •
Vmax
and
Amax
are used for automatic calculation of Scanner Delays and Laser Delays,
see activate_scanahead_autodelays.
• The values for
Vmax
and
Amax
are specified as control bits (galvanometer scanner
rotation angles). Information is read out from the correction file and used for an
internal conversion into programing bits (sample values). Therefore, the correction file
needs to be specified in the
TableNo
parameter. At conversion time, the correction file
must have been already loaded onto the RTC6 board, but does not yet need to be
assigned. The system cannot reliably detect correction files that have not been loaded.
The
Vmax
and
Amax
values which have been converted into programing bits can be
queried by get_scanahead_params(
HeadNo
=
256 )
.
