1395 Encoder Driver Interface Module
The Encoder Driver Interface module is a multi-purpose pulse amplifier
primarily used for generating 15 mA, double-ended, sink and source output
signals. These signals are acceptable as inputs to digital reference and/or digital
feedbacks into opto-isolated circuits of Bulletin 1395, 1336 PLUS, 1336
FORCE and 1399 drives. The opto-isolated input signals are designed to guard
against signal common loops and also to provide an improved signal to noise
input circuit.
See the Encoder Driver Interface Module Installation Instructions, publication
1395-IN010
, for more details.
1395 Digital Reference Adapter for RTP Applications
The Digital Reference Adapter board provides an interface between an external
device and the Bulletin 1395 drive Main Control board. When used with the
Reel-Tension-Paster (RTP) drive, the Digital Reference Adapter board allows the
drive to be commanded by a digital reference input signal from a single channel
encoder or frequency generator, whose shaft speed is equal to press speed. In this
application, a magnetic pickup with a gear ranging from 128 to 140 teeth
(dependent on printing diameter of the press) is used as the press speed sensor for
the drive.
This board also allows the drive to be controlled using combinations of internal
programmable relay logic at digital inputs 1…8, or through use of an analog
device such as a dancer potentiometer. When the analog device is used for
control, the dancer potentiometer provides position feedback sensing and
controls the reel speed through the P/I regulator located on the Digital Reference
Adapter board and the process trim regulator located on the Bulletin 1395 drive
Main Control board.

publication 1395-IN030
