Check that the inverter's input power and the control circuit power are both OFF.

CAUTION

• Do not install or remove this product while the inverter power is ON. Doing so may damage the inverter or this product.

• To avoid damage due to static electricity, static electricity in your body must be discharged before you touch this product.

12 INSTALLATION

2.2 Installation procedure

1. Remove the inverter front cover. (Refer to Chapter 2 of the Instruction Manual (Detailed) of the inverter for instructions for

removing the front cover.)

2. As shown in the next page, when the plug-in option is installed to the connector 1, insert spacers in the three mounting

holes that will not be tightened with mounting screws. (When the plug-in option is installed to the connector 2, insert

spacers in the two mounting holes.)

3. Fit the board mounted option connector on this product to the guide of the option connector on the inverter and insert the

plug-in option as far as it goes.

4. When the plug-in option is installed to the connector 1, fit the two locations, the left and right, of the product securely to

the inverter unit by screwing in the supplied mounting screws. (When the plug-in option is installed to the connector 2, fit

the three locations.) (Tightening torque 0.33 N∙m to 0.40 N∙m) If the screw holes do not line up, the connector may not be

inserted deep enough. Check the connector.

NOTE

• When installing/removing the plug-in option, hold the sides of the option. Do not press on the parts on the option circuit

board. Stress applied to the parts by pressing, etc. may cause a failure.

• Be careful not to drop mounting screws during the installation or removal of the plug-in option.

• The priorities of vector control compatible plug-in options are defined as follows: FR-A8AL > FR-A8APS > FR-A8APA > FR-

A8APR > FR-A8AP. The vector control compatible plug-in options with lower priority do not function.

• Only one option can be used. When multiple options are mounted, priority is given to option connectors 1, 2 and 3 on the

inverter in this order, and options having a lower priority do not function.

• When the inverter cannot recognize the option due to improper installation or any reason, the protective function (E.1 to E.3)

is activated and the inverter cannot be operated. The indication shown (when a fault occurs) depends on the connector used

(option connector 1 to 3).

• When removing the plug-in option, remove the two screws on either side, and then pull it straight out. Pressure applied to

the option connector and to the option board may break the option.

Motor used and switch setting

*1 Set according to the motor encoder used.

*2 Depending on the encoder to be used, prepare an external power supply (15 V) for the encoder. When the 24 V power supply of the FR-

A8AL is used, the power is supplied to the encoder through terminal PG24. When the 5 V/12 V power supply of the FR-A8AL is used, the

power is supplied to the encoder through terminal PGV.

*3 When the encoder output is the differential line driver type, only 5 V can be input.

NOTE

• Switch "SW1" is for manufacturer setting. Do not change the setting.

• When an external power supply is used for the encoder, turn OFF the encoder's power supply while power is not supplied to

the control circuit of the inverter. Otherwise, the plug-in option may be damaged.
