Chapter 2 OUTLINE OF SJ-FB
This manual describes the application board SJ-FB for a SJ300 series inverter.
This SJ-FB board, assembled in a SJ300 inverter, detected the rotation speed of a mo-
tor with the encoder and feedback the motor speed to suppress speed fluctuations for
highly accurate operation.
This SJ-FB board can also be used for controlling motor stop positions by entering 90
phase difference pulses, as well as for synchronized operation, orientation function, and
external torque limit input function.

How to Mount the option Board
Please combine the hole at four corners of the option board to each guide post for op-
tion positioning,and screw hole for the fixation of this side of the body. Then connect
the option board, in option port 1 or 2 of side of the body as shown below. Please fix 2
places of the board with the fixation screw of the belonging, to avoid loose connection.

4.3 Terminal connection diagram
Figure 4-2 Terminal wiring
(Note 1) : Please refer to the instruction manual of the inverter main body about the
wiring of the logic board.
(Note 2) : Use a twisted and shielded wire for the signal cables, and cut the shielded
covering as shown in the diagram below. Make sure that the length of the
signal cable is 20 meters or less. If the length exceeds 20 meters, please use
a VX application control device RCD-E (remote control device) or CVD-E (in-
sulation signal) to avoid malfunction caused by EMC noise or voltage drop.
Also, electric wire for the encoder uses twist shield line of 0.75mm2or more
(the example: Hitachi Cable, Ltd. KPEV-S), and make the distance less than
20m. In case of more than 20m, please use the relay amplifier of the 5V line
driver specification output. Insulate

Chapter 4 WIRING AND CONNECTION
(Note 3) : Please separate the main circuit wiring from the relay control circuit wiring.
If they have to be crossed, be sure that they must be crossed at right angle.
(Note 4) : Don’t make a short circuit between the EP5 and EG5 terminals. There is a
danger of malfunctions.
(Note 5) : Isolate common signal for analog signal of the main body (L terminal of the
logic card of SJ300) from common terminal of the SJ-FB.
(Note 6) : Please connect the encoder signal line properly so that the relationship
among their phases become as shown below during rotation of the mo-
tor(Standard EG5).
