Ctrl Command set_auto_laser_control
Function Initializes or deactivates “Automatic Laser Control“, see Chapter 7.4.9 ”“Automatic Laser
Control“”, page 197.
Call ErrorCode = set_auto_laser_control( Ctrl, Value, Mode, MinValue, MaxValue )
Parameters Ctrl Control parameter.
As an unsigned 32-bit value.
= 1…7: Defines which signal parameter is corrected by “Automatic 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 Control Signals
LASER1 and LASER2.
= 5: Output period ( HalfPeriod ) of the Laser Control Signals
LASER1 and LASER2.
= 6: Output value at the 16-bit digital output.
= 7: As 5. However, the pulse distance is geometrically constant
(“Spot Distance Control”).
= 0 or > 7: Deactivates “Automatic Laser Control“
(for Ctrl > 7: get_last_error return code RTC6_PARAM_ERROR ).
Value Defines the 100% value for the parameter selected by Ctrl .
As an 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 µs.
For Ctrl = 5: [0…(2
32
–1)].
1 bit equals 1/64 µs.
For Ctrl = 6: 16-bit values [0…65,535].
Higher bits are ignored.
Mode Speed-dependent laser control ( Mode =1…5) lets you select which data is to be
used for calculating speed-dependent correction.
As an unsigned 32-bit value.
=1: Set speed.
=2: Actual speed (as well as extensions, see below).
=3: Reserved.
=4: Reserved.
=5: Encoder speed (counter pulse rate).
