5.6.2 iParameters (F_iPar)
Application-dependent device characteristics are defined with the iParameters. A CRC
calculation is necessary for safe transmission of the iParameters, see chapter
"iParameters" on page 45.
The iParameters supported by the measuring system are listed below.

5.6.2.1 Integration time Safe
This parameter is used to calculate the safe speed, which is output via the cyclical
data of the safety module. High integration times enable high-resolution
measurements at low speeds. Low integration times show speed changes more
quickly and are suitable for high speeds and high dynamics. The time basis is
predefined to 50 ms. 50…500 ms can thus be set using the value range of 1…10.
Standard value = 100 ms.
5.6.2.2 Integration time Unsafe
This parameter is used to calculate the unsafe speed, which is output via the process
data of the non-safety module. High integration times enable high-resolution
measurements at low speeds. Low integration times show speed changes more
quickly and are suitable for high speeds and high dynamics. The time basis is
predefined to 5 ms. 5…500 ms can thus be set using the value range of 1…100.
Standard value = 100 ms.
5.6.2.3 Window increments
This parameter defines the maximum permissible position deviation in increments of
the master / slave scanning units integrated into the measuring system. The
permissible tolerance window is basically dependent on the maximum speed occurring
in the system and must first be determined by the system operator. Higher speeds
require a larger tolerance window. The value range extends from 50…4000
increments. Standard value = 1000 increments.
The larger the window increments, the larger the angle until an error will be
recognized.
