Name
PU: ON when the inverter is in the PU operation mode.
EXT: ON when the inverter is in the External operation mode. (ON when the inverter in the initial setting is powered
Operation mode indicator ON.)
NET: ON when the inverter is in the Network operation mode.
PU and EXT: ON when the inverter is in the External/PU combined operation mode 1 or 2.
MON: ON when the operation panel is in the monitoring mode. Quickly blinks twice intermittently while the protective
Operation panel status
function is activated.
indicator Slowly blinks when the display-off function of the operation panel is valid.
PRM: ON when the operation panel is in the parameter setting mode.
IM: ON when the inverter is set to control the induction motor.
Control motor indicator PM: ON when the inverter is set to control the PM motor.
The indicator blinks during test operation.
Frequency unit indicator ON when the actual frequency is monitored. (Blinks when the set frequency is monitored.)
Shows a numeric value (readout) of a monitor item such as the frequency or a parameter number.
Monitor (5-digit LED)
(The monitor item can be changed according to the settings of Pr.52, Pr.774 to Pr.776.)
PLC function indicator ON when the PLC function of the inverter is valid.
FWD key: Starts forward rotation operation. Its LED is ON during forward operation.
REV key: Starts reverse rotation operation. Its LED is ON during reverse operation.
Either LED blinks under the following conditions.
FWD key, REV key
• When the frequency command is not given even if the forward/reverse command is given.
• When the frequency command is equal to the starting frequency or lower.
• When the MRS signal is being input.
Stops the operation commands.
STOP/RESET key
Used to reset the inverter when the protection function is activated.
The setting dial of the Mitsubishi Electric inverters. Turn the setting dial to change the setting of frequency or
parameter, etc.
Press the setting dial to perform the following operations:
Setting dial • To display a set frequency in the monitoring mode (The monitor item shown on the display can be changed by using
Pr.992.)
• To display the present setting during calibration
• To display a fault history number in the fault history mode
Switches the operation panel to a different mode.
The easy setting of the inverter operation mode is enabled by pressing this key simultaneously with
MODE key
Every key on the operation panel becomes inoperable by holding this key for 2 seconds. The key inoperable function
is invalid when Pr.161="0 (initial setting)". (Refer to the FR-A800 Instruction Manual (Detailed).)
Confirms each selection.
When this key is pressed during inverter operation, the
SET key monitor item changes.
(The monitor item can be changed according to the settings
of Pr.52, Pr.774 to Pr.776.)
Goes back to the previous display.
ESC key
Holding this key for a longer time changes the display back to the monitor mode.
Switches between the PU operation mode, the PUJOG operation mode, and the External operation mode.
PU/EXT key
The easy setting of the inverter operation mode is enabled by pressing this key simultaneously with
Also cancels the PU stop warning.
