ENCODER PARAMETERS

Total measuring range

[Index 524]
This parameter sets the number of distinguishable steps over the total measuring range.
Allowed values are less than or equal to the total hardware resolution value (physical
multiturn resolution = number of physical counts per revolution + number of physical
revolutions).
We recommend the Number of revolutions to be set to a power of 2.
The set Number of revolutions results from the following calculation:
Number of revolutions =
Setting the Number of revolutions to a value which is a power of 2 is meant to avoid
problems when using the device in endless operations requiring the physical zero to be
overstepped. If you set the Number of revolutions which is not a power of 2, a so-called
"Red Zone" is generated before the physical zero. For more detailed information refer to
"
Red Zone" on page 70
Default = 134217728 (min. = 1, max. = 134,217,728)
NOTE
Example
The AMT58...13X14-PN encoder has a singleturn resolution of 13 bits (8,192 cpr) and a
multiturn resolution of 14 bits (16,384 revolutions). The permissible value for the Mea-
suring units / Revolution will be between 2
value for the Total measuring range will be between 2
