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/3 W galvanically isolated encoder power source. When using absolute
encoders the 12 single ended inputs are used. For quadrature encoders, the six
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.
ATTENTION: 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.
