7.10 Preset adjustment function
Risk of injury and damage to property by an actual value jump when the
Preset adjustment function is performed!
•
The preset adjustment function should only be performed when the
measuring system is at rest, otherwise the
resulting actual value jump must
be permitted in the program and application!

● In order that the preset adjustment function can be used in PNO CLASS 2
configurations, the operating parameter "Scaling function" must be
switched on!
● TR-Mode Position/TR-Mode Position+Velocity:
– Teach-In function, enabled with status:
Count direction and Preset adjustment can not be executed at the same
time. The bits 2
29
and 2
30
must be set to “0”.
The measuring system can be adjusted to an arbitrary position value in the range 0 to
(measurement length in steps - 1) via the PROFIBUS.
This is achieved by setting the highest value output data bit
(2
31
for PNO CLASS 2-32 bit configurations and the TR-Modes, or 2
15
for the PNO
CLASS 2-16 bit configuration).
The preset adjustment value sent in the data bytes with the rising flank of the bit
"preset execution" is adopted as the position value.
There is no acknowledgement of the process via the inputs in CLASS 2 mode.
