Absolute Encoders
Device Net
The encoders with Device Net interfaces are available in all mechani-
cal configurations.
They conform to the ISO 11898 and meet the V 2.0 specifications of the
ODVA.

Programmable parameters
Steps-turns : the resolution of the encoder is defined by the six following
terms :
- 13 bits multi-turn (29 bits) - 0 bit multi-turn (16 bits)
- 10 bits multi-turn (26 bits) - 13 bits single turn (13 bits)
- 2 bits multi-turn (18 bits) - 10 bits single turn (10 bits)
Rax : sets the output code to zero
Speed of transmission : configurable to :
- 125 Kb aud (value by default)
- 250 Kbaud
- 500 Kbaud
Address : defines the software address of the encoder on the 1 to 63 bus.
Value by default : id = 63
Methods of communication :
The interrogation of the encoder can be carried out following 4 modes :
• CYCLIC Mode
The encoder transmits its position on the activation of a programmed
Timer via the bus (with no answer).
With an answer , the master must send an acknowledgement of the posi-
tion of each frame.
• BIT STROBE Mode
A general demand by the master (broadcaster) permits the simultaneous
interrogation of a maximum of 64 devices.
• EXPLICIT Mode
This mode permits the programming and the interrogation of the parame-
ters of the encoder as well as its position.
• POLLING Mode :
The encoder transmits its position on the demand of the master.
BA output connection : Cable Gland output with a Mini C
connector at the end of a 1 m cable.
