Preset functions
Preset functions are used to set the position system according to a parameter value
(preset position) or actual position. The physical position of the driven machinery is
not changed, but the new position value is used as home position. Preset functions
can be used e.g. in synchron control to change the follower position without moving
the master.
The preset function trigger signal is selected by parameter 62.12 PRESET TRIG.
