• If the terminal block of the FR-A7NC is removed, the built-in terminating resistor cannot be used. (Refer to page 13.)

CAUTION

When wiring, take care not to subject the cable to stress. After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or

malfunction.

4.2 Operation Mode Setting

The inverter mounted with a communication option has three operation modes.

(1) PU operation [PU].............. Controls the inverter from the keys of the operation panel on the inverter or

parameter unit (FR-PU07/FR-PA07).

(2) External operation [EXT] ...Controls the inverter by switching ON/OFF external signals connected to

the control circuit terminals of the inverter. (The inverter is factory-set to this mode.)

(3) Network operation [NET] ... Controls the inverter with instructions from the network via the

communication option. (The operation signal and running frequency can be entered from the control circuit terminals depending on the Pr. 338 Communication operation

command source and Pr. 339 Communication speed command source settings. Refer to page 25.)

4.2.2

(1) Operation mode switching conditions

Before switching the operation mode, check that:

1) The inverter is at a stop;

2) Both the STF and STR signals are OFF; and

3) The Pr. 79 Operation mode selection setting is correct. (Set using the operation panel of the inverter or parameter unit (FR-PU07/FR-PA07).) Refer to the Inverter Manual for details of Pr. 79.

(2) Operation mode selection at power ON and at restoration from instantaneous power

The operation mode at power ON and at restoration from instantaneous power failure can be selected. Set a value other than "0" in Pr. 340 to select the Network operation mode. After started in Network operation mode, parameter write from the network is enabled. (Refer to page 76 for a program example for parameter write.)

REMARKS

• Change of the Pr. 340 setting is applied valid power ON or an inverter reset.

• Pr. 340 can be changed with the operation panel in any operation mode.
