Configure the ESUM
The ESUM combines the quadrature outputs of two encoders into a single quadrature output. The output quadrature may be selected to be either the sum or difference of the two quadrature inputs. The index from encoder 0 is wired to the index of the output. The index from encoder 1 is not used. Connectors are 5-pin positive latching.
Applications for the ESUM include:
The ESUM functions by sampling the two encoder inputs, decoding the quadrature inputs into up/down signals, combining the up/down signals, and synthesizing new quadrature on the output. The sampling nature of the operation limits the maximum quadrature frequency to 46.8 kHz.
To use, place the ESUM in line with the encoder cables. The ESUM derives its power from the +5V pin of the encoder cable. DIN rail mounting is available. Only SW1 affects the function of the ESUM. SW2, SW3, and SW4 are not used.
