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.
