8 Advanced Functions for Scan Head Control and Laser Control

This ASC hardware check also occurs
automatically by auto_cal(
Command
= 0 ) and if
required, for auto_cal(
Command
= 1 and 3 ), see
also auto_cal command description and
get_auto_cal.
• During execution of the measurement routine
determining the Home-In positions:
– the laser should be switched off
– no other commands should be sent to the
scan system
• For Gain/Offset Correction:
See Chapter 7.3.6 ”Output Values to the Scan
System”, page 181 #9.
After an initialization by load_program_file or
auto_cal(
Command
= 2 ), the following is set:
– Gain = 1.0
– Offset = 0
• For iDRIVE scan systems
(1)
, the following applies
in addition:
– At the beginning of a measurement routine,
the XY2-100 status word is automatically set as
to-be-returned by the scan system. At the end
of the measurement routine, the previously set
data type is restored.
– auto_cal aborts with an error result value 7 if
• auto_cal is to be executed for the first
scan head connector, and
• an “Automatic Laser Control“ in
Mode
= 2
(basic mode) has been activated, see Section
”Speed-Dependent Laser Control”, page 201.
The “Automatic Laser Control“ must be
deactivated before performing automatic self-
calibration.
– auto_cal also aborts (result value 1, 10 or 11),
if the scaling factor has been set by
control_command(
Data
= 12xx
H
) to a
value < 1. This is because the sensor positions
then are not reachable, see also
control_command(
Data
= 053F
H
). The
scaling factor must have been set to 1 (default
setting) by prior to automatic self-calibration
• control_command(
Data
= 1283
H
) and
• control_command(
Data
= 1200
H
).
