Parameters
(cont’d)
Mode
(cont’d)
For Mode = 2 above, the following extensions are available in any combination:
• M = +4 encoder speed-dependent correction
• M = +16 for SCANahead scan systems (instead of intelliSCAN)
• M = +32 The angle-synchronous galvanometer scanner speed is converted
into an Image Field synchronous speed with the help of the assigned
correction table.
Then the following applies: Mode = 2 + sum of extensions M.
For Mode = 0 or none of the above described ones:
Disables the speed-dependent or encoder-speed-dependent laser control
(get_last_error-Returncode: RTC6_PARAM_ERROR ). The position-dependent laser
control always remains effective with a valid value for Ctrl . See also Section
”Position-Dependent Laser Control”, page 199.
MinValue Defines the lower range limit of the parameter selected by Ctrl for automatic
correction and that cannot be undercut.
As an unsigned 32-bit value. Allowed values: see Value .
MaxValue Defines the upper range limit of the parameter selected by Ctrl for automatic
correction and that cannot be exceeded.
As an unsigned 32-bit value. Allowed values: see Value .
Result ErrorCode .
As an unsigned 32-bit value.
0 No error.
1 No first scan head active.
2 No iDRIVE scan system (see Glossary entry on page 27) active.
3 Invalid Ctrl value.
4 Invalid Mode value.
5 Access denied (board locked, get_last_error return code RTC6_ACCESS_DENIED ).
6 Mode extension M = +16: No SCANahead System connected or not active.
Comments • For usage of set_auto_laser_control, see Chapter 7.4.9 ”“Automatic Laser Control“”,
page 197.
• MinValue and MaxValue are automatically exchanged if MinValue > MaxValue and
MinValue is clipped to  Value and MaxValue clipped to  Value .
• Control data for speed-dependent laser control is exclusively derived from the
scan system data at the first scan head connector and then also applied for the second
scan head connector (if that connector has been activated and a scan system is
attached). At the time set_auto_laser_controlis called, the first scan head connector
must already have been assigned a correction table, otherwise error code 1 is returned
and Ctrl is set to 0. If only the second scan head connector is being used and/or the
scan system at the first scan head connector is shut off, then speed-dependent laser
control does not function.
