Incremental Encoder

Digital 2/3 channel incremental encoder IP

The Incremental Encoder IP process 2/3 digital inputs from incremental encoder to generate motor electric angle.

In 3 channels mode the index channel is used to reset counting at every mechanical round and prevent accoumulation of missing/extra pulses accumulation in simple 2 channels mode.

An internal digital filter with linear interpolation creates intermediates angle values to reduce ripple torque in case of low resolution encoders when used with large pair poles motors.
