4.3. Comparing function "
This function enables the operator to compare data stored in two memories that are selected from
among four memories of the parameter writer's memories A, B and C and the inverter's memory as well
as to search a parameter which is different in the setting value from others.
The comparing function cannot be used for editing data because it is provided for searching parameters
which are different in setting values from others.
Use the "Remote keypad" function described in Section 4.6 to edit data.

When the parameter writer is turned on as it is connected with the inverter,
"chc" appears on the display first and then "init" appears to indicate that
the power supply is being initialized. Lastly, the display shows "copy".
−Selecting a desired function−
Select to "comp" (comparing function) with the SFT key.
Each time the SFT key is pressed, indication on the display changes from
"copy' to "comp" (comparing function). "prot " (memory protecting
function), "clr" (memory initializing function) and to "copy" again in this
order.
−Entering the selected function−
After selecting "comp" with the SFT key, press the ENT key and "in"
(selecting inverter memory) appears on the display.
−Selecting a memory to compare its data with another−
Each time the SFT key is pressed, indication on the display changes from
''in" (selecting inverter memory) to "a'' (selecting memory A), "b"' (Selecting
memory B), "c" (selecting memory C) and to "in" again in this order.
Select the copy destination area.

If the memory A is selected as the memory storing the original data, indications
differently appear as shown in parentheses.
−Entering the selected memory to compare its data with the original−
After selecting "in
the inverter's memory for example) with the SFT key, press the ENT key and
the parameter writer starts comparing data of the two memories with each
other.
−Executing comparing data (searching different parameters)−
After confirming that "f000" is appearing on the display, execute comparison
of data in order of communication number (refer to the Table of communication
numbers.). When the parameter writer searches a parameter different from the
other, it discontinues comparing operation and shows the parameter's
communication number in blinking numerals.
Press the ENT again to continue the comparing operation.
−Comparing is complete−
With completion of data comparison, "end" appears on the display first and
then "_ _" of a check data (check sum of the original data) appears. Value of
the check data changes depending on the condition of the original data.
−Ending comparing−
Press the ENT key and indication on the display returns to "comp".
