In the applications that need higher speed accuracy or in positioning applications,
motor shaft speed feedback with an incremental encoder is necessary.
The connection to the inverter is done through the terminals XC32:1 to XC32:9,
according to the table 2. This input presents encoder fault detection.
The auxiliary encoder connection is done through the terminals XC32:10 to
XC32:18, according to the table 2.
This input can be used in applications that need an external encoder to perform
positioning or following blocks.
However, it cannot be used for the motor speed feedback, which is done by the
main encoder. This input does not present encoder fault detection.
