Description:
ATYPE
parameter for Encoder Daughter Board = 3
The encoder daughter board provides an encoder input without a servo feed-
back facility for measurement, registration and synchronization functions on
conveyors, drums, flying shears, etc. The encoder port provides high speed
differential receiver inputs. These inputs are opto-isolated to maximise the
noise immunity of the system. The encoder port also provides an isolated 5v
output capable of powering most encoders. This simplifies wiring and elimi-
nates external power supplies.
The encoder daughter board provides a hardware position capture function for
both the encoder Z input and the dedicated 24volt registration input. Transi-
tions of either polarity on both these inputs can be used to record the position
of the axis at the time of the event within less than 1 micro second. This prac-
tically eliminates time delays and avoids interrupting the processor frequently
in multi-axis systems.

Encoder Connections:
The encoder is connected via a 9 pin 'D' type socket mounted on the front
panel. The plug supplied should be cable mounted and wired as shown below.
The encoder port is designed for use with differential output 5 volt encoders.
