5.8.6 Starting position
The starting position is the position which is automatically assumed after the reference
run has been effected before the travel program is started. If no starting position is
specified, the drive remains in the position in which the reference run has ended until a
travel data set is started.
The following options are provided:
ƒ None:
The drive stops near the home position after the reference run has been completed.
The distance to the home position depends on the reference speed and the negative
acceleration.
ƒ Software limit switch, left/right
The drive traverses to the position of the left or right software limit switch and
remains in this position until a travel data set is started.
ƒ
Resolver offset
The drive traverses to the position of the resolver offset. The resolver offset is set on
the ”System” tab.
5.8.7 Reference
If a manual reference start is set, it can be actuated via the ”Start”, ”Mark”, or ”Position”
keys. The individual functions are specified in the following.
Start
By means of the ”Start” key, the reference run is started according to the settings effected
in the ”Reference” tab (reference type, reference speed,…).
Mark
The current actual position of the drive is accepted as zero position and therefore as home
position. All further settings of the ”Reference” tab in this connection are ignored. After
activating the ”Mark” key, the drive is considered as referenced.
Position
Below the ”Position” key, a position value in the default unit can be entered, which is
directly accepted as zero position or as a current actual position when the ”Position” key
is activated. After the ”Position” key has been activated, the drive is considered as
referenced.
