General procedure
(if the encoder is connected to the digital inputs DI1 and DI2)
1. Define the function of the digital inputs DI1 and DI2 in
2. Set the encoder increments in
.
3. Select "1: Encoder signal FreqIn12" in
4. Adapt the filter time of the speed measurement in
.
5. In the case of encoders with a very low resolution (number of increments < 120 increments):
Change the encoder evaluation procedure in
if necessary.
