80190-759-01, 80190-759-02 Universal Encoder Interface
The Universal Encoder Interface enables connections between the drive and to
an absolute position encoder or a standard quadrature encoder, providing 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, use the 12 single ended inputs. For quadrature
encoders, use the 6 differential inputs.
Either encoder with frequencies up to 200 KHz connects 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.

ATTENTION: Removing the Universal Encoder Interface with active control
power may damage the board. Disconnect the control power before removing
the board.
