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 C00115/1
.
2. Set the encoder increments in C00420/1
.
3. Select "1: Encoder signal FreqIn12" in C00495/1
.
4. Adapt the filter time of the speed measurement in C00497/1
.
5. In the case of encoders with a very low resolution (number of increments < 120 increments):
Change the encoder evaluation procedure in C00496
if necessary.
