8.24 Encoder as drive object
Figure 8-15
Supplementary conditions
To be able to create an "Encoder" drive object, the following conditions must be fulfilled:
● All encoders that can be assigned to a drive can be used.
● Encoder drive objects may be connected to all DRIVE-CLiQ ports.
● Up to 4 DRIVE-CLiQ HUBs (DMC20 or DME20) can be used to establish a star-shaped
wiring of the Encoder drive objects. This means that a maximum of 19 possible "Encoder"
drive objects can be connected to one Control Unit. This means that the number of possible
"Encoder" drive objects is restricted so that a maximum of 24 drive objects can be
connected to one Control Unit.
● The DRIVE-CLiQ HUBs must be directly connected to the Control Unit.
● All encoders that can be assigned to a drive can be used.
● "Encoder" drive objects may be connected to all DRIVE-CLiQ ports.
● Up to 4 DRIVE-CLiQ HUBs (DMC20 or DME20) can be used to establish a star-shaped
wiring of the "Encoder" drive objects. This means that a maximum of 19 possible "Encoder"
drive objects can be connected to one Control Unit.
(This means that the number of possible "Encoder" drive objects is restricted so that a
maximum of 24 drive objects can be connected to one Control Unit.)
● The DRIVE-CLiQ HUBs must be directly connected to the Control Unit.
Procedure
To create an "Encoder" drive object, proceed as follows:
1. Double-click "Insert encoder".
The "Insert Encoder" dialog box opens.
2. Enter a name for the encoder in the "Name:" input field.
3. Click the "Drive object no." button.
4. Enter a new drive object number in the "Drive object no." input field.
All assigned drive object numbers are shown in the "Assigned drive object no." list.
