Fig. 9-11 Possible baud rate depending on the cable length
The EQN1325, ECN1313 and EQI1325 encoders require a
6FX_002-2EQ10-____ connecting cable.
Not all measuring system manufacturers support baud rates up to
2 Mbaud. The serial protocol for the motor encoder is only required for
initialization and redundancy monitoring. These functions are non-time-
critical. A baud rate of 100 kHz (standard setting) is recommended for
immunity to interference.
Only encoders which generate incremental tracks, in addition to
transmitting the position using the serial protocol, are suitable as motor
encoders. The sensor board supports the serial SSI and EnDat
protocols.
Recommended coded rotary encoders:
