Components of the operation panel
Basic operation
a
The monitor items can be changed.
b
In each fault record display, "0" is displayed instead of the fault indication when no fault record exists.
c
"P. 0" will appear if the MODE key is pressed during parameter setting.
Changing the parameter setting value
Change the setting of Pr.1 Maximum frequency.
Operating procedure
.
Basic parameters
a
The factory setting depends on the performance class of the frequency inverter.
Overview of the error messages
If a protective function has been activated, eliminate the cause of the error and then reset the frequency
inverter. It is imperative that you follow the procedure in the instruction manual for the FR-CS80 frequency
inverter. You can reset the frequency inverter by pressing the STOP/RESET button on the operation panel
(only after a serious error), by switching the power supply off and on again, or by switching the RES signal.

Description
STOP/
RESET key
Stops the operation commands.
Used to reset the inverter when the protective function is activated.
,
UP/DOWN
key
Used to change the setting of frequency or parameter, etc.
The following operations are also enabled:
N
Displaying the present setting during calibration
N
Displaying a fault record number in the fault history
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 nor
-
mal 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.
SET key
Confirms each selection.
Pressing this key in a mode other than the parameter setting mode
will display parameter settings.
RUN key
Used to give the start command to the inverter.
The rotation direction depends on the Pr.40 setting.

If a parameter write condition is not satisfied, a parameter write error appears on the LCD display.
N
When Pr.77 Parameter write selection = "2 (initial value)", the parameter setting change is available
only while the inverter is stopped and under the PU operation mode. To enable the parameter setting
change while the inverter is running or under the operation mode other than PU operation mode,
change the Pr.77 setting.
