QUADRA-602A Encoder Module Operations Manual
l
TTL single ended input for both X channel, Y channels, XINDEX and YINDEX
l
Operating environment 0 to 50 degree centigrade
Note
l
Quadra-602a is designed for single ended TTL input, but it is also applicable for differential
input by connecting mnus signals to the RESERVED screw termnal blocks on the opposite
edge of the board.
l
Since noises are most sensitive to LS7266, XINDEX and YINDEX is recommended wiring to
GND of the board if they are not used for the application.
l
If XINDEX and YINDEX have to be used and too much noises at these lines, the counter
l
Quadra-602a is for Mcrosoft Windows.
Connecting sensors
The +12v supply fromthe board can only provides 150mA current, and you have to make sure
the total current requirement of sensors for x and y channels are limted within 150mA. A very
heavy load may cause the onboard DC-DC generating too much heat. Short circuit of the
board-supplied powers is strictly not allowed.
The inputs of board are TTL compatible. A level below 0.5v is recognized as logic low, and a
level beyond 2v is recognized as logic high. Though all Quadra-602a modules are input-protected
with a 180-ohmresistor to avoid damage to the LS7266R1, the input signal is recommended not
to exceed 5v.
As for sensors with differential RS422 level output, just use XA+, XB+, YA+, YB+, XINDEX+ and
YINDEX+ for module Quadra-602a; XA-, XB-, YA-, YB-, XINDEX- and YINDEX- are not going to
