4. BASIC OPERATION
4.1 Operation panel
PU: ON when the inverter runs in the PU operation mode.
EXT: ON when the inverter runs in the External operation mode. (ON when the inverter
in the initial setting is powered ON.)
mode LED indicator
PU and EXT: ON when the inverter runs in the External/PU combined operation mode.
PU and EXT (blinking): Blinks when the inverter runs in the Network operation mode.
Operation panel mode
ON when the operation panel is in the monitor mode. Quickly blinks twice intermittently
while the protective function is activated.
ON or blinks during inverter operation.
ON: During forward rotation operation
Blinks slowly: During reverse rotation operation
Blinks quickly: Operation is disabled although the start command is given.
Hz: ON when the actual frequency is monitored. (Blinks when the set frequency is
A: ON when the current is monitored.
Shows a numeric value (readout) of a monitor item such as the frequency or a parameter
Monitor display (4-digit
(The monitor items can be changed according to the settings of Pr.774 to Pr.776.)
Stops the operation commands.
Used to reset the inverter when the protective function is activated.
Used to change the setting of frequency or parameter, etc.
The following operations are also enabled:
• Displaying the present setting during calibration
• Displaying a fault record number in the fault history
Switches the monitor screen (item) in the monitor mode. Every key on the operation
panel becomes inoperable (locks) by holding this key for 2 seconds. The key lock
function is disabled when Pr.161 = "0 (initial value)".
Holding this key for one second displays the initial screen. (During normal inverter
operation it will appear as the first screen in the monitor mode; during abnormal
operation it will appear as the first screen in the fault history mode.
Reverts to the previous screen if pressed during frequency setting when the easy setting
function is enabled..
Initial setting in monitor mode
Confirms each selection.
Pressing this key in a mode other than the parameter setting mode will display
Used to give the start command to the inverter.
The rotation direction depends on the Pr.40 setting.
