wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.

• Before wiring or inspection, power must be switched OFF. To

confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

• Any person who is involved in wiring or inspection of this

equipment shall be fully competent to do the work.

• The plug-in option must be installed before wiring. Otherwise,

you may get an electric shock or be injured.

• Do not touch the plug-in option or handle the cables with wet

hands. Otherwise you may get an electric shock.

• Do not subject the cables to scratches, excessive stress,

heavy loads or pinching. Otherwise you may get an electric shock.

REMARKS

• Remove a plug-in option after removing two screws on both left and right sides. (The plug-in option is easily removed if the control circuit terminal block is removed before.)

INSTALLATION

CAUTION

• One of " to " (option fault) appears when the inverter cannot rec-

ognize the option because it is improperly mounted, etc. One of the faults also appears when an incompatible option is mounted to the inverter. Different indication will appear according to the mounted position (connector 1, 2, or 3).

• For an inverter having several option connectors, use the bottom connector to

mount the option.

If it is connected to a connector other than the bottom connector, " " or

" " (option fault) will appear and its operation will be disabled. Different indication will appear according to the mounted position (connector 1 or 2).

• The number of option connectors differs by the model. The table below shows

2.4 Node address setting

Set the node address between "1 to 64" using node address switches on the FR-A7NF (Refer to page 7). The setting is applied when the power turns OFF once, then ON again. Set the arrow (×) of the corresponding switches to the number to set a desired address. z Setting example

Node address 1: Set the "×" of X10(SW1) to "0" and the

X10

"×" of X1(SW2) to "1".

CAUTION

• Set the node address switch to the switch number position correctly. If the switch is set between numbers, normal data communication can not be established.

• If the node address switch is set to a value other than "1 to 64", it is invalid due to outside of setting range. In this case, DEV LED of the option is lit red and E.OPT appears on the operation panel of the inverter.

• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)

• Set the inverter node address before switching ON the inverter and do not change the setting while power is ON. Otherwise you may get an electric shock.

• Changes in the node address setting are applied only at the next power-ON. Therefore, if the node address setting is changed, make sure to power OFF and ON the inverter power.

Do not connect the parameter unit (FR-PU07, etc.) to the FR-A7NF communication connector. Doing so will damage the option.

When performing wiring using the space between the inverter front cover and control circuit terminal block, take care not to subject the cable to stress.

After wiring, wire offcuts must not be left in the inverter. They may cause an error, failure or malfunction.

Function

Started in Network operation mode. Operation mode can be changed between the PU operation mode and Network operation mode from the operation panel. Parameter values written by communication are written to the EEPROM and RAM. There is no waiting time since the communication line fault occurrence until communication error (0s). Note that actual time depends on the detection time on FL remote network. The inverter decelerates to stop at communication fault occurrence, when provide a fault output. Automatic communication option recognition Normally, control source of the RS-485 terminal is valid. When a communication option is mounted, the control source of the communication option is valid. Selects the PU connector as the PU operation mode operation source.
