4 BASIC OPERATION This chapter explains the basic operation of this product. Always read the instructions before use. 4.1 Operation panel 4.1.1 Components of the operation panel 66 4. BASIC OPERATION 4.1 Operation panel N o. Appear ance N ame Description (a) In m verter operation ode LED indicator 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.) 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.
(b) O L peration panel mode ED indicator ON when the operation panel is in the monitor mode. Quickly blinks twice intermittently while the protective function is activated. In rter operating us indicator 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. (c) (d) Unit indi cator Hz: ON when the actual frequency is monitored. (Blinks when the set frequency is monitored.) A: ON when the current is monitored. (e) Mon LED isplay (4-digi t Shows a numeric value (readout) of a monitor item such as the frequency or a parameter number.
(The monitor items can be changed according to the settings of Pr.774 to Pr.776.) (f) STOP/R ESET key Stops the operation commands. Used to reset the inverter when the protective function is activated. (i) , UP/DOWN key 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 (j) MODE key 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 Output Output Output Operation mode frequency current voltage Faults history switchover (k) SET key Confirms each selection. Pressing this key in a mode other than the parameter setting mode will display parameter settings. (l) RUN key Used to give the start command to the inverter.
The rotation direction depends on the Pr.40 setting.
