Component
Name
Description
(a)
Operation mode
indicator
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.
(b)
Operation panel status
indicator
MON: ON when the operation panel is in the monitoring 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.
(c)
Control motor indicator
IM: ON when the inverter is set to control the induction motor.
PM: Not used.
The indicator blinks during test operation.
(d)
Frequency unit
indicator
ON when the actual frequency is monitored. (Blinks when the set frequency is monitored.)
(e)
Monitor (5-digit LED)
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
.)
(f)
PLC function indicator
ON when the PLC function of the inverter is valid.
(g)
FWD key, REV key
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.
• 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.
(h)
STOP/RESET key
Stops the operation commands.
Used to reset the inverter when the protection function is activated.
(i)
Setting dial
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 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
(j)
MODE key
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 the Instruction Manual (Detailed).)
(k)
SET key
Confirms each selection.
When this key is pressed during inverter operation, the monitor
item changes.
(The monitor item can be changed according to the settings of
Pr.52, Pr.774 to Pr.776
.)
(l)
ESC key
Goes back to the previous display.
Holding this key for a longer time changes the display back to the monitor mode.
(m)
PU/EXT key
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 simultaneously with
.
Also cancels the PU stop warning.
