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 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 monitor mode. Quickly blinks twice
intermittently while the protective function is activated.
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.
PM: ON when the inverter is set to control the PM motor.
The indicator blinks during test operation.
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.
(The monitor item can be changed according to the settings of Pr.52, Pr.774 to Pr.776.)
ON when the PLC function of the inverter is valid.
FWD key: Starts forward rotation operation. Its LED is ON during forward rotation
operation.
REV key: Starts reverse rotation operation. Its LED is ON during reverse rotation
operation.
Either LED blinks under the following conditions.
• 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.
Used to reset the inverter when the protective 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:
• To display a set frequency on the LED display in the monitor 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
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
192.)
Confirms each selection.
When this key is pressed during inverter
operation, the monitor item changes.
(The monitor item on each screen can be
changed according to the settings of Pr.52,
Pr.774 to Pr.776.)
Goes back to the previous display.
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.
The easy setting of the inverter operation mode is enabled by pressing this key
