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".
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 display
s
err
(blinking).
To get out of the error state indicated by a blinking
err
or
cper
, press the
key.
When
cper
is blinking, it indicates that the function code number does not match. But in this case the function
codes which are consistent completely can continue copying after pressing
key.
While
cper
is blinking, pressing
key changes display to flashing of
err
.
(*) Ace(E2S) series of ROM version number less than 500 or Lift(LM2) series does not support “
chec
”.
Data protection
You can protect data saved in the keypad from unexpected modifications. Enabling the data protection that was disabled
changes the display
read
on the "Data Copying" function list to
proT
, and prohibits data reading from the inverter.
To enable or disable the data protection, follow the steps below.
(1) Select the "Data Copying"
(
'cpy
)
on the function selection menu in Programming mode.
(2) When the
'cpy
is displayed, holding the
key down for at least 5 seconds alternates data protection status between
enabled or disabled.
For switching the data protection status, be sure to hold the
key down for at least 5 seconds. Once the key is
released within 5 seconds, press the
key to go back to the
' cpy
display and perform the keying operation
again.
