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, eg, in synchron control to change the follower position without moving
the master.
The preset function trigger signal is selected by parameter
There are three different preset functions:
• SYNCH REF: Preset drive synchron reference chain
to the value of
• ACT TO SYNCH: Preset drive synchron reference chain
GEARED) to the value of actual position
• WHOLE SYSTEM: Preset whole position system of the drive to the value of
