Chap. 3 OPERATION USING THE KEYPAD
Basic keying operation
(1) Turn the inverter ON. It automatically enters Running mode. In that mode, press the
key to switch to Programming
mode. The function selection menu appears.
(2) Use the
and keys to display "Data Copying" (
'cpy
).
(3) Press the
key to proceed to the list of data copying functions (e.g.
read
).
(4) Use the
and keys to select the desired function, then press the key to execute the selected function. (e.g.
read
will blink.)
(5) When the selected function has been completed,
end
appears. Press the key to return to the list of data copying
functions. Press the
key again to return to the menu.
Table 3.17 below lists details of the data copying functions.

Function Description
read
Read data Reads the function code data out of the inverter’s memory and stores it into the keypad
memory.
Also reads out inverter’s current running status information which can be checked by FRENIC
Loader, such as information of I/O, system, alarm, and running status.
Pressing the
key during a read operation (when
read
is blinking) immediately aborts the
operation and displays
err
(blinking).
If this happens, the entire contents of the memory of the keypad will be completely cleared.
copy
Write data Writes data stored in the keypad memory into the inverter’s memory.
If you press the
key during a write operation (when
copy
is blinking), the write operation
that is under way will be aborted and
err
will appear (blinking). If this happens, the contents
of the inverter’s memory (i.e., function code data) have been partly updated and remain partly
old. Therefore, do not operate the inverter. Instead, perform initialization or rewrite the entire
data.
If this function does not work, refer to "
If data copying does not work" on page 3-22.
ueri
Verify data Verifies (collates) the data stored in the keypad memory with that in the inverter's memory.
If any mismatch is detected, the verify operation will be aborted, with the function code in
disagreement displayed blinking. Pressing the
key again causes the verification to continue
from the next function code.
Pressing the
key during a verify operation (when
ueri
is blinking) immediately aborts
the operation and displays
err
(blinking).
err
appears blinking also when the keypad does not contain any valid data.
proT
Enable Data
protection
Enables the Data protection of data stored in the keypad’s memory.
In this state, you cannot read any data stored in the inverter’s memory, but can write data into
the memory and verify data in the memory.
Upon pressing the
key the inverter immediately displays
err
.
chec
Read inverter
running
information
Reads out inverter’s current running status information that can be checked by FRENIC
Loader, such as information of I/O, system, alarm, and running status, excluding function
code data.
Use this command when the function code data saved in the PC should not be overwritten and
it is necessary to keep the previous data.
Pressing the
key during a read operation (
chec
blinking) immediately aborts the
operation and displays
err
(blinking).
To get out of the error state indicated by a blinking
err
or
cper
, press the key.
