WARNING

Only qualified personnel shall carry out wiring work. Otherwise, there is a danger of electric shock and/or fire.

Implement wiring after checking that the power supply is off. Otherwise, there is a danger of electric shock and/or injury.

Be sure not to touch the inside and terminal of the option board while the inverter is energized. Otherwise, there is a danger of electric shock and/or i nj ury.

Be sure not to remove the encoder line and feedback board during the operation. Otherwise, there is a danger of electric shock and/or fire.

After a lapse of more than 10 minutes after turning off the input power supply, perform the maintenance and

inspection.

Otherwise, there is a danger of electric shock

Make sure that only qualified persons will perform maintenance, inspection and part replacement.

(Before starting the work, remove metallic objects from your person. Be sure to use tools protected

with insulation)

Otherwise, there is a danger of electric shock and/or injury.

Never modify the unit. Otherwise, there is a danger of electric shock and/or injury.

Be sure to implement wiring after installing the body. Otherwise, there is a danger of electric shock and/or injury.

CAUTION

Do not allow substance such as cutting waste, sputtering of welding, waste of iron, wire and dust etc. to come

into contact with the unit.

There is a fire risk.

Inverter main body and option board must be fixed tightly with the screw of the belonging. There is a fear of contact defectiveness.

Tighten the screws of the encoder line on the option board so that there is no loose connection. There is the fear of contact defectiveness.

Confirm that the power supply of the encoder is the same as the one in the option card (DC5V). Otherwise, there is the danger of injury and/or fire.

Make sure that the direction of the motor is correct. There is a danger of injury or machine damage.

Make sure there is no abnormal noise and vibration. There is a danger of injury or machine damage

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 motor 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 fun ction, and external torque limit input function.
