Parameters
Operation mode is specified with X16, X65,
and X66 signals.
(when X16, X65, and X66 signals are
assigned)
Change to the NET operation mode by setting as shown below.
(1) X66 signal is ON (when only X66 signal is assigned)
(2) X66 signal is ON (when only X16 and X66 signals are assigned)
(3) X66 signal is ON (when all X16, X65 and X66 signals are assigned)
-
Command for changing to NET operation
mode from EXT operation mode is given
only from the operation location with NET
operation control source.
(when X16, X65, and X66 signals are not
assigned)
Change the operation mode from the operation location with control
source.
-
By making parameter setting, operation
mode can be changed.
(when X16, X65, and X66 signals are not
assigned)
Set a value other than 0 in communication startup mode selection (Pr.
340) to reset the inverter.
Pr. 340
Restricted by parameter setting.
Set 0 in operation mode selection (Pr. 79). After changing to PU
operation mode, change to NET operation mode.
Pr. 79
Operation mode change is restricted with
X12 and MRS signals.
When X12 signal is assigned, turn X12 signal ON. When X12 signal is
not assigned, turn MRS signal ON.

Parameters
Operation mode cannot be directly
changed from PU operation to NET
operation with the current parameter
setting.
After changing to EXT operation, change to NET operation. If the
operation mode will not change to EXT operation, return to "Status
Display" screen to execute troubleshooting of "EXT Operation".
Change communication start up mode selection(Pr. 340) to change
directly to PU operation. After changing Pr. 340, reset the inverter.
Pr. 340
Operation mode is specified with X16, X65,
and X66 signals.
(when X16, X65, and X66 signals are
assigned)
Change to the NET operation mode by setting as shown below.
(1) X65 signal is ON
(2) X66 signal is ON (when only X16 and X66 signals are assigned)
(3) X66 signal is ON (when all X16, X65 and X66 signals are assigned)
-
Command for changing to NET operation
mode from PU operation mode is given
only from the operation location with PU
operation control source.
(when X16, X65, and X66 signals are not
assigned)
Change the operation mode from the operation location with control
source.
