10 Preset Adjustment Function
WARNING!
NOTICE!
Danger of death, serious physical injury and/or damage to property due to
uncontrolled start-up of the drive system during execution of the preset
adjustment function!
The relevant drive systems must be locked to prevent automatic start-up.
It is advisable to protect the preset triggering via the F-Host by means of
additional protective measures, such as e.g. key-operated switch, password etc.
The new position must be checked after execution of the preset function.
The preset adjustment function is used to set the currently output position value to any position
value within the measuring range. The displayed position can thus be set to a machine
reference position purely electronically.
The execution of the preset adjustment function is a critical process, as the resulting actual
value jump, e.g. when using a controller, could cause uncontrolled machine movements. The
preset adjustment function may therefore only be executed when the relevant system part is at
a safe standstill.
After completion of the preset process, you must check that the position output by the
measuring system matches the position transmitted to the measuring system.
The preset adjustment function is already locked in the measuring system and can only be
activated via the variable
IPAR_EN
in the F-Periphery-DB
DB1638
. Even if all preconditions are
fulfilled from the viewpoint of the F-Host, the preset adjustment function is only executed when
the shaft of the measuring system is stationary. However, a certain edge jitter, e.g. caused by
machine vibrations, is permitted within a certain tolerance window. This tolerance window can
be set with the iParameter
Idleness tolerance Preset
, see chapter 6.7.2.4 “Idleness
tolerance Preset“ on page 50.
