80190-759-01, 80190-759-02 Universal Encoder Interface

The Universal Encoder Interface allows the drive to be connected to an
absolute position encoder or a standard quadrature encoder and also
provides the option for dual or redundant quadrature encoders. The
Universal Encoder Interface provides 12 single ended or 6 differential,
optically isolated inputs as well as a 12V/3Watt galvanically isolated
encoder power source. When using absolute encoders the 12 single ended
inputs are used. For quadrature encoders the 6 differential inputs are used.


Either type of encoder with frequencies up to 200 KHz, can be interfaced
to the Universal Encoder Interface.


The 80190-759-02 Universal Encoder Interface is functionally identical to
the 80190-759-01 with the addition of conformal coating. The Universal
Encoder interface is configured via jumpers installed on the 12-position
header J4. The header has three positions labeled ‘Park’ and used to store
the jumpers when indicated as “Removed” in the table below. Each
function is selected by moving its corresponding jumper from the ‘park’
location to the selected function location if labeled “Installed”. The
following table describes the functions available.

Removing the Universal Encoder Interface while
control power is applied may result in damage to
the board. Only remove the board when the
control power is Off.
