3. Encoder operating modes
3.1. Poll Mode
In Poll Mode the encoder will transmit upon request of another user. The data transferred may optionally
comprise position data or an additional warnflag and alarmflag.
3.2. Change of status Mode (COS)
The encoder will transmit position data without being requested by another user if the actual process value
has changed by a certain value (adjustable COS-Delta).
3.3. Cyclic Mode
The encoder will transmit position data without being requested by another user upon expiry of a
programmable time interval (adjustable 1…65535 ms).
4. Encoder operating parameters
Significance of operating parameters
Parameter Significance Value range Default
setting
decimal hex Bit (decimal)
Sense of
rotation Behaviour of the output code
depending on the sense of
rotation of the shaft when
looking at the flange
CW = increasing values with
clockwise rotation
CCW = increasing values with
counterclockwise rotation CW = 0
CCW = 1 CW = 0h
CCW = 1h CW = 0
