SCALING FUNCTION PARAMETERS

SCALING FUNCTION PARAMETERS
Using the scaling function parameters the absolute position value of the encoder is con -
verted by the software in order to customize the resolution of the encoder according to
needs. The scaling parameters will only be activated if the parameters Class 4 function -
ality and Scaling function control are enabled.
The permissible range for the scaling parameters is limited by the hardware resolution
of the encoder.
Example
In a 27-bit encoder having a singleturn resolution of 13 bits (8,192 cpr) and a number of
revolutions of 14 bits (16,384 revolutions), the permissible value for the Measuring
units / Revolution is between 2
0
and 2
13
(2
13
= 8,192) while the permissible value for
the Total measuring range is between 2
0
and 2
27
(2
27
= 2
13
* 2
14
= 134,217,728).
Measuring units / Revolution
[Index 523]
It is used to program a user specific resolution per each revolution (singleturn resolu
-
tion). Allowed values are less than or equal to the hardware counts per revolution
(physical singleturn resolution). We suggest setting values that are a power of 2 (1, 2, 4,
… 2048, 4096, …). See the parameter Total measuring range below.
Default = 8192 (min. = 1, max. = 8,192)
Example
The AMT58...13X14-PN multiturn encoder has a singleturn resolution of 13 bits (8,192
cpr); the permissible value for the Measuring units / Revolution will be between 2
0
and
2
13
(2
13
= 8,192).
NOTE
There is no functionality of this parameter if the Scaling function control
parameter is disabled.
NOTE
When you change the value next to this parameter, then you are required to
enter a new preset.
