Scaling Function Parameters; Measuring Units / Revolution - Datalogic AMT58 Series Manual

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
the Total measuring range is between 2

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)
NOTE
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
