Command and Parameter Values (Code
L
)
0A
H
UpdatePermanentMemory (as of Firmware Version 2078):
This command (with its only allowable parameter value of Code
L
= 00
H
) causes
the currently set servo behavior to also be the default start behavior following
subsequent resets (also see page 160).
0E
H
SetControlDefinitionMode
This command specifies which information about a particular tuning (i.e. the
corresponding servo algorithm) is to be returned from the scan system via the
selected status channel. Code
L
[0…3] thereby defines the tuning number.
As with the SetMode command, tuning information are returned as signed 20-bit
values.

Bit #19 (MSB) = 0: Tuning available
= 1: Tuning not available

Bits #4…7 Tuning type:
= 0: Vector tuning (microvectorization)
= 1: Jump tuning
= 2,3: reserved
Bits #0…3 = 0

H
SelectControlDefinition (as of Firmware Version 2078):
For scan systems equipped with multiple tunings (i.e. servo algorithms), this
command selects a desired tuning (also see page 155). Code
L
thereby defines the
tuning number.
Default setting: Code
L
= 00
H
12
H
SetPositionScale (as of Firmware Version 2072):
This command can be used to set a (down) scale factor for the position values (the
servo electronic scales the position values received from the RTC
®
5 by the
specified factor, also see page 160). The command must be issued initially with
the parameter Code
L
= 83
H
and a second time with the desired parameter value
(see the following list).
In the default setting (Code
L
= 00
H
), the scale factor is 1 (no scaling).
Code
L
Effect on the scale factor
00
H
The scale factor is set to the value 1
(but first execute the command code
Data = 1283
H
!)
01
H
The scale factor is set to the value 1/2
(but first execute the command code
Data = 1283
H
!)
02
H
The scale factor is set to the value 1/4
(but first execute the command code
Data = 1283
H
!)
03
H
The scale factor is set to the value 1/8
(but first execute the command code
Data = 1283
H
!)
