Pr. 79 Pr. 340 Operation mode selection

Pr.79 Operation mode selection Pr.340 Communication startup mode selection

￿Used to select the operation mode of the inverter.

You can freely change between operation by external signal (external operation), operation by PU (FR-DU07) (PU operation), operation by combination of PU operation and external operation (external/PU combined operation) and network operation (when RS-485 terminals or a communication option is used).

￿Specify operation mode at power on (Pr.340)

When power is switched on or when power comes back on after instantaneous power failure, the inverter can be started up in the network operation mode.

After the inverter has started up in the network operation mode, parameter write and operation can be performed from a program. Set this mode for communication operation using the inverter RS- 485 terminals or communication option.

You can set the operation mode at power on (reset) according to the Pr. 79 and Pr. 340 settings.

*1 The Pr. 340 setting "2" or "12" is mainly used for communication operation using the inverter RS-485 terminals.

When a value other than "9999" (selection of automatic restart after instantaneous power failure) is set in Pr. 57 Restart coasting time, the inverter will resume the same operation state which was in before after power has been restored from an instantaneous power failure.

*2 The operation mode cannot be switched directly between the PU operation mode and network operation mode.

*3 Operation mode can be changed between the PU operation mode and

network operation mode with key of the operation panel (FR- DU07) and X65 signal.

Pr. Simple magnetic flux vector 80, 90 control

Pr.80 Motor capacity (simple magnetic flux vector control)

Pr.90 Motor constant (R1)

Providing optimum excitation to the motor can also produce high torque in a low-speed region. (simple magnetic flux vector control)

Set the used motor capacity (equal to or one rank higher than the inveter capacity) in Pr. 80.

The number of motor poles should be any of 2, 4 and 6 poles.

Single-motor operation (one motor for one inverter)

Wiring length from inverter to motor should be within 30m.

When simple magnetic flux vector control is not used, set "9999" (initial value) in Pr. 80.

For Pr. 90 Motor constant (R1), normally setting is not necessary. When you need more torque under simple magnetic flux vector control for other manufacturer's motor, set the motor primary resistance value (R1) for connection in Pr. 90

Pr. indicates simple mode parameters and Pr. indicates extended parameters. When setting parameters, refer to the instruction manual (applied) and understand instructions.
