Command
set_wobbel_control
Function specifies laser control parameters for laser power variation with “freely definable wobbel
shapes”.
Call
set_wobbel_control( Ctrl, Value, MinValue, MaxValue )
Parameter Ctrl control parameter for initializing or deactivating laser power variation as an
unsigned 32-bit value:
= 1…6: specifies which signal parameter to vary: For more information, see
set_auto_laser_control.
= 0 or > 6: deactivates laser power variation (for
Ctrl > 6: get_last_error
return code
RTC5_PARAM_ERROR ).
Value Nominal laser power P0 (100%) as an unsigned 32-bit value.
For the allowed range, see set_auto_laser_control; the maximum is
[0 … 65535] or 0xFFFFFFFF. Excessive values will be clipped.
MinValue ,
MaxValue
Limits that can’t be exceeded, as unsigned 32-bit values (see
set_auto_laser_control).
The allowed ranges depend on the selected
Ctrl parameter and on Value .
Comments • For
Ctrl = 0 and Ctrl > 6, laser power variation will be switched off (initialization state
after load_program_file). The values for McBSP multi transfers will then not be used.
•The limits for
Value , MinValue , MaxValue are the same as for automatic laser control (see
set_auto_laser_control), but with a maximum of [0 … 65535]. Initialized values are
MinValue = 0 and MaxValue = 0xFFFFFFFF, i.e. no restrictions.
• If you want variable laser power along a wobbel shape, then the command must
execute before you activate the “freely definable wobbel shape”. Otherwise, laser
power won’t be varied, even if you make a change in the data sets.
• Special case: if
Value = 0xFFFFFFFF, then the nominal laser power will be derived from
the port assigned by the signal parameter
Ctrl , instead of from the command. This will
then be the current content at this timepoint set via other normal commands, e.g.
write_da_1_list for
Ctrl = 1.
But beware: with execution of a “freely definable wobbel shape”, the value at the port
can change at any time. Subsequent calls of set_wobbel_control will then return other
values for the nominal laser power.
