O
When the MRS signal is being input.
H
STOP/RESET key
Stops the operation commands.
Resets 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:
O
To display a set frequency on the LED display in the monitoring mode
(the monitor item shown on the display can be changed using Pr. 992.)
O
To display the present setting during calibration
O
To display a fault history number on the LED display in the faults history mode.
J
MODE key
Switches the operation panel to a different mode.
Pressing the "MODE" and "PU/EXT keys simultaneously switches to the easy setting
mode.
Every key on the operation panel becomes inoperable by holding this key for 2

Instruction Manual (Detailed).)
K
SET key
Confirms each setting.
Switches the monitor screen in the monitor
mode.
(Using Pr. 52 and Pr. 774–Pr. 776, the
