About of the setting values "10, 12, 20, 22" to Pr. 340 "link startup mode selection"
1) Switching between the PU operation mode and network operation mode is enabled.
When Pr.340="10 or 12" and Pr.79="0 or 6", operation can be switched between the PU operation and
network operation from the operation panel (FR-DU04) or parameter unit (FR-PU04).
• FR-DU04
Shifts to the PU operation mode when

• FR-PU04
Shifts to the PU operation mode when the
the key is pressed.
2) Switching between the external operation mode and network operation mode by the external terminal
(Addition of the setting of "66" to Pr.180 to 186 "input terminal function selection")
When "20 or 22" is set in Pr.340 "link start up mode selection", switching between external operation and
network operation can be performed by the external terminal.
Setting Signal Name
66
Note: 1. "66" can be set even when the setting values of Pr.340 "link start up mode selection" are other
than "20 and 22" or when a communication option is not connected. However, operation can not
be switched by the X66 signal.
2. For the X66 signal, operation only from the external terminal is valid independently of the setting
of Pr.338 "operation command source", Pr.339 "speed command source" (can not be operated
from the network).
3) Switching between link start up mode and operation mode
The inverter starts up in the network operation mode at power-on.
