The table below gives an overview of the available registers. The individual meaning
is described in the following chapters
Register
Index
Name Function Units
Value range
Read / write registers
0 CMode Sets the way the
set current will be
determined
- 0 = digital current setting
1 = profile current setting
2 = analogue current setting
Bit 0 reset
(default)
If a pyrometer is connected, the
measured values are being
used.
Bit 0 set If a pyrometer is connected, the
calibrated values are being
used.
Bit 1 reset
(default)
Current is set as defined in
analogue or digital current set.
1 Rmode Closed loop
control mode
-
Bit 1 set Two-Point temperature closed
loop control is active. Current
will switch between threshold of
the laser diode and the analogue
or digitally defined current max.
Bit 0 reset Gate signal of customer IO is
being ignored.
Bit 0 set
(default)
In addition to the other
conditions, the gate signal of the
customer IO needs to be active
in order to allow for emission of
laser light.
Bit 1 reset Ready Signal is active, if laser
unit is ready. Interlock does not
need to be closed.
2 Gmode Regulates the
control
characteristics of
the inputs and
outputs. Bit coded.
See description.
-
Bit 1 set
(default)
Ready Signal is only active, if
laser unit is ready and Interlock
is closed and secured.
0: Laser off/ profile stopped
0->1: Laser switches on or profile is
started
3 Activation Defines the
conditions for the
laser to be
switched on or off
or, if in profile
mode, for a pulse
train to be
triggered.
-
2 (default):
Laser will switch on or profile will
be started if the trigger signal
switches from inactive to active
