5.8.2
Speed or velocity reference
The selection of the speed/velocity reference is effected at the output end in the value and
units defined by the conversions and display units. The direction and amount of the
reference speed is adjustable depending on the process and influence the course of the
referencing. More detailed information can be gathered from the individual descriptions
of the reference type.
5.8.3
Torque/force reference
The selection of the torque/force reference is effected in the value and units defined by the
conversions and display units. Limiting the reference torque is particularly required with
regard to the reference type ”Limit stop, left/right”, in order to avoid damages on the
mechanics or in the drive train. The value of the reference torque is to be selected
depending on the respective process.
5.8.4
Start reference
The definition of when the reference run is to be carried out or started is effected under
”Reference start”. The following options can be selected.
Powerup
Immediately on connection of the supply voltage (without calling up a travel data set), a
reference run in accordance with the programmed settings is automatically carried out.
First start
With regard to the first start of a travel data set, the reference run is carried out directly
before the travel data set is effected. The reference run is carried out according to the
programmed settings.
Manually
A reference run is carried out if the ”Start” key in the ”Reference” menu is pressed.
Input
The reference run is started by activating the digital input of a function module. For this,
the ”Start reference” function has to be assigned to the freely configurable input. The
reference run is effected in the programmed settings.
5.8.5
Reference type
None
In applications for which no referencing is required, the reference type ”None” is to be
selected. This setting for example is reasonable for speed-controlled systems.
Note!
If no reference run is required for the process, the following setting is
recommended:
