Yaskawa Microtrac DSD Drives LAN Interface PCB - Manual (Page 2)

INTRODUCTION
The Terminal Transition Adapter PCBs
allow the customer to make input and output
wiring connections for the Local I/O boards
without opening the MicroTrac DSD power
cube. There are landings provided for customer
wiring. Up to a single 16 AWG wire can be
landed per termination point. The Terminal
Transition Adapter PCBs come in different con-
figurations to allow ribbon cables with different
conductor counts (20, 26 or 34) to interface
them to appropriate connectors on the Local
I/O boards.
Each Local I/O board can be used with
up to 2 or 3 Terminal Transition Adapter PCBs.
They are designed for mounting on a panel near
the MicroTrac DSD power cube; with the addi-
tion of a Transition Board Mounting Bracket
(MagneTek part no. 43T00182-0000), up to the
maximum 6 Terminal Transition Adapter PCBs
can be mounted directly on the side of the
power cube (see Figure 1).
INPUT/OUTPUT DESCRIPTIONS
The types of signals connected to each Terminal
Transition Adapter PCB are dependent upon
which Local I/O board it is connected to.
INSTALLATION AND HOOKUP
This board is factory installed on the drive and
should require no further connections to be
made to it. However, if it should become neces-
sary to install the board in the field, then the
following steps should be taken:
WARNING
HAZARDOUS VOLTAGES CAPABLE OF
SEVERE INJURY OR DEATH MAY BE PRESENT
WITHIN CABINET. BEFORE OPENING CABI-
NET DOOR, DISCONNECT AND LOCK-OUT
INCOMING POWER.
CAUTION
TO AVOID DAMAGE TO ELECTRONIC COMPO-
NENTS, DO NOT MAKE ANY CONNECTIONS
WITH POWER APPLIED. USE PROPER ELEC-
TROSTATIC DISCHARGE (ESD) PROCEDURES
WHEN HANDLING PRINTED CIRCUIT BOARDS.
1. Turn off incoming power.
2. Locate where this board is to be physically
mounted. Refer to the System Schematic for
the location. If the board is to be installed on
the
side of the power cube, but no bracket is pres-
ent, use the appropriate (#6) hardware to attach
the bracket to the power cube chassis.
3. If replacing an existing board, then discon-
nect all cablse and wires to the board from their
connectors. Then unmount the existing board.
4. Mount this board into its proper position.
5. Connect all of the cables and wires per the
Interconnection Diagram..
Refer to the equipment Interconnection Dia-
gram for detailed wiring information. Ensure
that wire size and disconnect devices conform to
the installation contractor’s drawings and to all
applicable codes. Observe the following:
A. In long cable runs, take care to prevent
excessive voltage drop.
B. Separate the leads used for speed reference,
feedback, and other low level signals from those
used for the motor armature, field and AC
power. Do not run these two groups in the same
conduit or wire trough.
C. Provide shielded and twisted leads as indicat-
ed on the schematic and Interconnection
Diagrams. Connect all shields on shielded wire
to system common (not ground) on one end
only. Use Twisted shielded pair wire for long
runs.
SETUP
There are no switches, jumpers, or poten-
tiometers to set up.
