10. (D) Operation Command and Frequency Command
10.1 Operation mode selection
• Set "4" in
Pr.79
. The mode cannot be changed to other operation modes.
Operation mode switchover during operation (Pr.79 = "6")
• During operation, the inverter operation mode can be switched from among the PU, External, and Network (Network
operation mode is selectable via RS-485 communication or Ethernet communication, or when a communication option is
used).
PU operation interlock (Pr.79 = "7")
• The operation mode can be forcibly switched to the External operation mode by turning OFF the PU operation external
interlock (X12) signal. This function will be usable in a case where the inverter does not reply to external command signals
during operation due to the operation mode accidentally unswitched from the PU operation mode to the External operation
mode.
• To input the X12 signal, set "12" in any parameter from
Pr.178 to Pr.184 (Input terminal function selection)
to assign
the function. (For details on
Pr.178 to Pr.184
• Set
Pr.79
= "7" (PU operation interlock).
• If the X12 signal is not assigned, the function of the MRS signal is switched to the PU operation interlock signal from MRS
(output stop).

PU
operation
Use the operation panel to change the operation mode to the PU operation mode.
• The direction of motor rotation does not change due to the operation mode change from the External
operation mode.
• The previous setting of frequency which has been set using a potentiometer (frequency command) is taken
over. (However, note that the setting disappears when the power is turned OFF or when the inverter is reset.)
External operation
→
NET
operation
Give the command through communication to change the operation mode to the Network operation mode.
• The direction of motor rotation does not change due to the operation mode change from the External
operation mode.
• The previous setting of frequency which has been set using a potentiometer (frequency command) is taken
over. (However, note that the setting disappears when the power is turned OFF or when the inverter is reset.)
PU operation
→
External
operation
Press the key on the operation panel to change the operation mode to the External operation mode.
• The direction of operation is determined by external input signals used in the External operation mode.
• The setting frequency is determined by the external frequency command signal.
PU operation
→
NET
operation
Give the command through communication to change the operation mode to the Network operation mode.
• The direction of motor rotation and the frequency setting does not change due to the operation mode change
from the PU operation mode.
NET operation
→
External
operation
Give the command through communication to change the operation mode to the External operation mode.
• The direction of operation is determined by external input signals used in the External operation mode.
• The setting frequency is determined by the external frequency command signal.
NET operation
→
PU
operation
Use the operation panel to change the operation mode to the PU operation mode.
• The direction of motor rotation and the frequency setting does not change due to the operation mode change
from the Network operation mode.

ON
Switching of the operation mode (External, PU, and NET) is
enabled. The signal is OFF during External operation.
Enabled.
OFF
Operation mode is forcefully changed to the External operation
mode.
External operation is enabled.
Switching to the PU or NET operation mode from the External
operation mode is disabled.
Disabled except for
Pr.79
