PROGRAMMABLE PARAMETERS

Resolution: defines the resolution per revolution (0 à 4 096).

Transmission speed : programmable from 10kBaud (1 000m) to 1 Mbaud (25 m) ; value per default : 20 Kbaud.

Address : defines the software address of the encoder on the bus (1 à 127, Value per default : id = 1).

Direction : defines the direction of count of the encoder.

RAX : define the value of the current position (stationnary shaft).

Cames : high and low limits.

COMMUNICATION MODES

Encoder configuration : Reading/Writing of the encoder objects dictionnary (SDO mode).

3 modes are available to interrogate the encoder position/speed :

CYCLIC mode : the encoder transmits its position in an asynchronous manner. The frequency of the transmission is defined by the

programmable cyclic timer register from 0 to 65 535 ms,

SYNCHRO mode : the encoder transmits its position on a synchronous demand by the master.

POOLING mode (Answer to a RTR signal) : the encoder only answers to a request.
