• If activated by set_wobbel_control and set_wobbel_mode ( Mode = 3 ), the following
applies:
– The RTC6 varies the current laser power P within the wobbel shape section according
to
– P100 (as with Mode = 2) is the nominal laser power as it would be without the
wobbel figure. It is set by set_wobbel_control( Ctrl, Value, MinValue, MaxValue ) :
• With Value = 0…65,535, the specified Value value is used
• With Value = 0xFFFFFFFF, the value is taken over that has been last outputted to
the port Ctrl .
– Factor is an unsigned 16+bit value with scaling 16,384 = one (default value). The
initial Factor value can be set to nnnn by Value = 0xFF00nnnn and another
set_wobbel_control call. The parameters Ctrl , MinValue and MaxValue are taken over
from the latest set_wobbel_control call.
– To change the 100% performance, set_wobbel_control can be called at any time.
However, the initial Factor value only becomes effective when the Wobbel Mode is
switched on newly. At wobbel shape runtime, Factor cannot be changed by
set_wobbel_control.
– Factor is changed per Microstep additively by the dPower value from
set_wobbel_vector( dTrans, dLong, Period, dPower ) . The maximum value is
65,535 (Factor 4) and cannot be exceeded.
– Power modulation via McBSP (as with Mode = 2) is not possible.
