Operation mode switching and communication startup mode (Pr.79, Pr.340)
Operation mode switching conditions
Operation mode switching conditions
• The inverter is at a stop;
• Both the STF and STR signals are off; and
• The
Pr.79 Operation mode selection
setting is correct.
(Set with the operation panel of the inverter.)
Operation mode selection at power ON and at restoration from instantaneous power failure
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 Communication startup mode selection
to select the network operation mode.
After started in network operation mode, parameter write from the network is enabled.
NOTE
• Change of the
Pr.340
setting is valid when powering on or resetting the inverter.
•
Pr.340
can be changed with the operation panel independently of the operation mode.
• When setting a value other than 0 in
Pr.340
, make sure that the initial settings of the inverter are correct.
• When the inverter has received a communication establishment request from the master in the External operation
mode or switchover mode, the operation mode is switched to the NET operation mode.
However, after the error reset, the inverter enters the External operation mode and no communication establishment
request may be sent from the master. Thus, setting
Pr.340
"0" in advance is recommended.
• Refer to the Instruction Manual (Detailed) of the inverter for details of
Pr.79, Pr.340
.
