CAUTION

NOTE

HAZARDOUS HIGH VOLTAGE

Motor control equipment and electronic controllers are connected to hazardous line voltages. When servicing drives and electronic controllers, there might be exposed components with cases or protrusions at or above line potential. Extreme

This is the "Safety Alert Symbol. " This symbol is used to call your attention to items or operations that could be dangerous to your and/or other persons operating this equipment. Read the messages and follow these instructions carefully.

WARNING

Indicates a potentially hazardous situation which, if not avoided, can result in serious injury or death.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, can result in minor to moderate injury, or serious damage of product. The mat t ers des c ribed u nd er may, i f not av o ided, lead to serious results depending on the situation. Important matters are described in CAUTION ( as well as WARNING ), so be sure to observe them.

CAUTION

NOTE

Notes indicate an area or subject of special merit, emphasizing either the product's capabilities or common errors in operation or maintenance.

care should be taken to protect against shock. Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with another person in case an emergency occurs. Disconnect power before checking controllers or performing maintenance. Be sure the equipment is properly grounded. Wear safety glasses whenever working on electronic controllers or rotating electrical equipment.

WARNING

Only qualified personnel should 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 inside the inverter case and terminals of the option board while the inverter is energized. Otherwise, there is a danger of electric shock and/or injury.

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

Do not perform maintenance or inspection until 10 minutes or more after turning off the

input power supply.

Otherwise, there is a danger of electric shock

Make sure that only qualified persons will perform maintenance, inspection and part replacement. Before starting 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 inverter body. Otherwise, there is a danger of electric shock and/or injury.

CAUTION

Do not allow materials such as cutting waste, welding sputter, wire fragments, solder

balls, dust etc. to come into contact with the unit.

There is a fire risk.

Inverter main body and option board must be mounted securely. There is a risk of intermittent connection due to vibration.

Tighten the screws of the encoder line on the option board so that there is no loose connection. There is a risk of intermittent connection due to vibration.

Confirm that the power supply rating of the encoder is the same as the option card (DC 5V). Otherwise, there is the danger of damage, 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 or vibration during operation. There is a danger of injury or machine damage.

Chapter 1 GENERAL DESCRIPTIONS

Chapter 2 OUTLINE OF SJ-FB

This manual describes the option board SJ-FB for the SJ300 series inverter. This SJ-FB board, installed in an SJ300 inverter, detects the rotation speed of a motor by accepting pulses from a shaft-mounted motor encoder, achieving highly accurate speed regulation. This SJ-FB board can also be used to control motor stop position by inputting 90 degree out-of-phase (quadrature) pulses, as well as for synchronized operation between multiple inverters (master/slave or electronic gear), orientation function, and external torque limit input
