Call
control_command( Head, Axis, Data )
Parameter
Head
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)
Axis
Number of the axis as an unsigned 32-bit value; allowed values:
= 1: X axis (STATUS channel, galvanometer scanner 2)
= 2: Y axis (STATUS1 channel, galvanometer scanner 1)
Data
Command code with optional parameter as unsigned 32-bit value:
The upper part (bits#16-31) of this parameter is
not evaluated, only the lower part (bits#0-
15) is evaluated. The more significant data byte of the lower part Code
H
(bits#8-15)
represents a command code and the less significant data byte Code
L
(bits#0-7) an
optional parameter. For each command code the corresponding command and its allowed
parameter values are described below.
Example: With
Data
= 0501
H,
i.e. Code
H
= 05
H
(command SetMode ) and Code
L
= 01
H
, the
actual position is selected to be returned from the scan system.

Command and Parameter Values (Code

)
05
H
SetMode : This command selects the data signal to be returned from the scan
system for the specified axis via the respective status channel (also see page 153 ).
Each Code
L
parameter value c orresponds to a particular data type.
• Default setting: Code
L
= 00
H
(XY2-100 status word)
• The data types marked in grey are only relevant for the intelli WELD
®
.
i DRIVE
®
scan systems with SL2-100 interface return signed 20-bit values. Scan
systems with XY2-100 Enhanced interface return signed 16-bit values; here the
XY2-100 converter converts (by multiplying by 16) the returned values to signed
20-bit values.

Bit #19 (MSB), 11 = 1: Internal voltages normal
Bit #18, 10 = 1: Galvanometer scanner temperature within normal range
Bit #16, 15, 8, 7 = 1: X- and Y-axis position error within normal range
Bit #17, 12, 9, 4 = 1
Bit #14, 6 = 1 (for intelli WELD
®
and for scan systems with sensors for
automatic self calibration: Reserved)
Bit #13, 5 = 0
Bit #0…3 = 0
