Ctrl Command set_auto_laser_control
Function initializes or deactivates position- and/or speed-dependent or encoder-speed-dependent laser
control
Call
ErrorCode = set_auto_laser_control( Ctrl, Value, Mode, MinValue, MaxValue )
Parameters
Ctrl
Control parameter (unsigned 32-bit value) for initializing or deactivating position-
and/or speed-dependent or encoder-speed-dependent laser control:
= 1 … 6: defines which signal parameter will be automatically corrected via position-
and/or speed-dependent or encoder-speed-dependent laser control:
= 1: 12-bit output value at the ANALOG OUT1 output port
= 2: 12-bit output value at the ANALOG OUT2 output port
= 3: output value at the 8-bit digital output port
= 4: pulse length (
PulseLength
) of the laser signals LASER1 and LASER2
= 5: output period (
HalfPeriod
) of the laser signals LASER1 and LASER2
= 6: output value at the 16-bit digital output
= 0 or > 6: deactivates position-, speed- and encoder-speed-dependent laser control
(for
Ctrl
> 6: get_last_error return code
RTC5_PARAM_ERROR
)
Value
defines the 100% value for the parameter selected via
Ctrl
(unsigned 32-bit value);
allowed values:
for
Ctrl
= 1/2: 12-bit values [0 … 4095], higher bits are ignored.
for
Ctrl
= 3: 8-bit values [0 … 255], higher bits are ignored.
for
Ctrl
= 4: [0 … (2
32
–
1)], 1 bit equals 1/64 µ s
for
Ctrl
= 5: [0 … (2
32
–
1)], 1 bit equals 1/64
µ
s
for
Ctrl
= 6: 16-bit values [0 … (2

–
1)], higher bits are ignored.
Mode
Control parameter (unsigned 32-bit value) for initializing or deactivating speed-
dependent or encoder-speed-dependent (but not position-dependent) laser control.
Speed-dependent laser control (
Mode
=1…5) lets you select which data is to be used
for calculating speed-dependent correction.

RTC5_PARAM_ERROR
)
MinValue
defines the lower range limit of the parameter selected via
Ctrl
for automatic
correction and that cannot be undercut (unsigned 32-bit value);
allowed values: see
Value
MaxValue
defines the upper range limit of the parameter selected via
Ctrl
for automatic
correction and that cannot be exceeded (unsigned 32-bit value);
allowed values: see
