n
With
1-fold
evaluation one signal edge 0-1 of
Track A
corresponds to one counter
pulse respectively one division of the system to be scanned corresponds to one
counter pulse.
n
With
4-fold
evaluation one signal edge of
Track A
and
Track B
corresponds to one
counter pulse. The 4-fold evaluation is very often used.

Encoder - deployment
There is the possibility to connect an encoder via I/O1 and I/O3 respectively via I/O2 and
I/O4. With the value 1 of object
‘0x8F00-01 - Encoder Feedback configuration’
the encoder function for I/O1 and I/O3 of drive 1 is enabled. The System
SLIO motion module works in a closed-loop mode Positioning and velocity loops are
closed Current values of position, velocity, acceleration and deceleration are calculated
by the System SLIO motion module itself. Via
‘0x8F00-02 - Encoder actual value’
the encoder value can be read and further processed in you user program. If
there is one encoder connected, the unused digital in-/outputs are further free for usage.

*) For each drive, there is an object dictionary whose structures are identical. Please note that the descriptions always relate to drive 1, unless otherwise noted. To access drive 2,
you have to add 0x1000 to the corresponding object.
