Ctrl Command auto_cal
Function controls the functions for (automatic self-) calibration of the scan system attached to the
specified scan head connector.
Call
ErrorCode = auto_cal( HeadNo, Command )
Parameters
HeadNo
Command
Result error code or type of sensor system as an unsigned 32-bit value:
3
6
the following error codes are only returned after Command = 0 ... 3:
0
1, 10, 11
2, 20, 22
4, 40, 44
5, 50, 55

the following error code is only returned after Command = 0 or 4, and even then only if no
other errors occurred:

10 Commands And Functions
Number of the scan head connector as an unsigned 32-bit value,
allowed values:
= 1: primary scan head connector
= 2: secondary scan head connector (activation required)
Control parameter (as an unsigned 32-bit value,
allowed value range: [0 ... 4]):
®
= 0: The RTC 5 detects the current Home-In positions, stores them in the
DLL and in the RTC
initializes the gain and offset values (Gain = 1.0, Offset = 0).
®
= 1: The RTC 5 detects the current Home-In positions,
calculates and sets the new gain and offset values and thereby
activates drift compensation.
®
= 2: The RTC 5 deactivates drift compensation by initializing the gain and
offset values (Gain = 1.0, Offset = 0).
®
= 3: The RTC 5 detects the current Home-In positions
(but – in comparison to Command = 1 – leaves the gain and offset
values unchanged and i.e. does not activate drift compensation
®
= 4: The RTC 5 checks the ASC hardware (i.e. checks whether a scan
system attached to the specified scan head connector is equipped
with an internal sensor system for automatic self-calibration – Home-
In sensors) and returns the type and status of the detected sensor
system. The detected type is also stored in the RTC
The command cannot be executed because the board is currently BUSY or INTERNAL-BUSY
Parameter error.
No error.
Home-In sensor not found (this could also mean a Home-In sensor is defective)
(1: for X axis (galvanometer scanner 2)
10: for Y axis (galvanometer scanner 1)
11: for both axes).
The spread in measured values during a measurement cycle is too high
(2: for X axis / 20: for Y axis / 22: for both axes).
Reference data not found (only for
(4: for X axis / 40: for Y axis / 44: for both axes).
Calibration error (Error during calibration or error in reference data)
(5: for X axis / 50: for Y axis / 55: for both axes);
(for DLL version 519 or lower) this return value could also mean the scan system contains no Home-
In sensor(s).
Error: automatic laser control activated in Mode 2
