5.3. Warning indications
Warning indications: Indicated by flashing LED display.
Warning Code Problem and Solutions
prot
The target memory to copy data or to initialize is write protected. Copying any data to the
memory or initializing the memory cannot be executed. Press the [ESC] key to cancel.
deVe
The type of device is different (different in series or voltage class or capacity of inverter).
Press the [ENT] key to copy between two inverters of different capacity or voltage class. Press
the [ESC] key to cancel copying. If “sup” (system area parameters) protection has been
disabled by setting “prot”(memory protection) to “off”, the copying cannot be executed
even if the [ENT] key is pressed. Copying to the inverter of a different series is impossible.
After copying between two inverters with different capacities, the type information parameters
depending on the inverter capacity or voltage class should be initialized. See the inverter
instruction manual on how to initialize them.
erRa
erRb
erRc
Indicated memory is not found or has been corrupted.
This indication appears when memory A, B, or C is selected to copy data from, to compare data
to, or to protect data, but no data can be found in the selected memory (including the case when
power was turned off during the previous copying operation), or a CRC code error occurred in
the selected memory. Press the [ESC] key to cancel.
In this case the data has to be rewritten.
f_ _ _
(title number)
Indicates the title number of the parameter that was found to be different while using
comparison function, or that can not be written while using the copying function. Press the [ENT]
key to continue, the [ESC] key to cancel.
When Remote Keypad did not find any data in one memory, it flashes “%” in case the data is
missing in the memory that was selected first, or “Hz” if it is missing in the memory that was
selected second. This may happen parameter data may be missing when the software versions
of two inverters are different.
N.B.: Parameter titles are written to the inverter memory in consecutive order. When Remote
Keypad indicates missing or mismatched data by flashing a parameter title number on the
display, all prior parameter titles will have been written to the inverter already.
_ _ _ _
(4 digits CRC code)
When CRC code difference of parameters was found as a result of comparison, two alternating
CRC code indicates appear in the display window. In this case, there is a different parameter. If
the title of different parameter is not found, execute comparison again after setting “sup” in
memory protection function to “off”.
5.4. Other problems
Phenomenon
Problem and Solutions
Display is
extinguished.
Check the connection of the serial communication cable.
Check the kind of the serial communication cable.
Check that the power of the inverter is turned on.
% lamp and Hz
lamp are not lit
When Remote Keypad is connected to the following inverters, % lamp and Hz lamp is not lit.
VF-S11, VF-nC1, VF-S9, VF-A7, VF-P7, etc.
Key is not effective It needs to be repaired.
[EASY] key is effective only for the inverter with [EASY] key.
Parameters can
not be written
Some parameters can not be written while the inverter is running. See the instruction manual of
the inverter.
Copying the parameters between inverters of different series is impossible.
