Rockwell Automation 1391ES SUP INST-A QUAD B OPTION - Manual (Page 3)

A Quad B Board
Instructions
Wiring Figure 2 provides interconnect information between the position controller
and TB3 on the A Quad B Board. Refer to Figure 1 for board location.
ATTENTION: To guard against possible damage to the A
Quad B Board, assure that wiring between TB3 and the position
controller is correct. Refer to Figure 2.

1 Recommended Wire – Belden #9728 or equivalent. Maximum distance between the A Quad B
Board and the position controller is 40 feet (12.2 meters) using a 5 volt signal. For distances up
to 300 feet (91 meters), 18 gauge wire and an 8 to 15V DC power supply must be used.
2 For proper operation when interconnecting to IMC products, the B and B (NOT) signals must be
reversed.
When interfacing to IMC 121 or 123 controllers, use the 1391-CAQB cable.

Setup and Operation The A Quad B option operates in the same manner as the Allen-Bradley
845H Line Driver Encoder (26LS31 line driver output). The option
requires either a regulated +5V DC at terminal 7 or an unregulated +8 to
+15V DC input at terminal 9 (board draws 125mA maximum). The pulse
train output is selectable to 256, 512, 1024 or 2048 lines per revolution via
the Encoder Output switch, S3 (see Figure 3). S3 selects the line count that
will be output from the A Quad B Board.
ATTENTION: Incorrect setting of S3 can cause erratic and/or
improper machine motion which may result in personal injury
or equipment damage. Assure that switch S3 has been properly
set as shown in Figure 3.
