Ctrl Command set_softstart_mode
Function switches softstart mode on or off.
Call
set_softstart_mode( Mode, Number, Delay )
Parameters All parameters are unsigned 32-bit values.
Parameter
Mode

Comments • The command set_softstart_mode must be called before first-time use of the
set_softstart_level
analog voltage values (default setting for softstart value handling: Mode = 3).
• The individual softstart values Level(0) – Level(Number – 1) must be provided individ-
ually via separate calls of set_softstart_level. Indices for which no Level value was
supplied are undefined.
• If the values for Mode or Number are invalid, then softstart mode will be switched off.
• When softstart mode is switched off, the already transmitted values are not deleted and
can be further used after a renewed switch-on. Here, you shouldn't unintentionally
switch between analog voltage values (Mode = 1, 2, 11 or 12) and pulselenghts (Mode
= 3 or 13). In contrast, you can switch at any time between ANALOG OUT1 (Mode = 1
or 11) and ANALOG OUT2 (Mode = 2 or 12).
• The softstart mode is incompatible with the pixel mode (see
set_softstart_mode will be executed, but softstart will not be executed while pixel
mode is operational.
• The softstart mode should not be used in conjunction with automatic laser control (see
page
ANALOG OUT1 or ANALOG OUT2 output ports or pulse lengths (PulseLength) or
output periods (HalfPeriod) of the laser signals LASER1 and LASER2.
Softstart mode cannot be combined with "freely definable wobbel shapes". If one is
defined and activated, the command will have no effect.
