Function codes are indicated by the following based on whether they can be changed or not when
the inverter is running:

Y*
Possible
If the data of the codes marked with Y* is changed with
keys,
the change will immediately take effect; however, the cha
saved into the inverter's memory. To save the change, press th

key.
If you press the
key without pressing the
key to exit the current
state, then the changed data will be discarded and the previous data will
take effect for the inverter operation.
Y
Possible
Even if the data of the codes marked with Y is changed with
and
keys, the change will not take effect. Pressing the
key will make the
change take effect and save it into the inverter's memory.

Copying data
The data copying feature copies the function code data stored in the inverter's memory into the
keypad's memory. With this feature, you can easily transfer the data saved in a source inverter to
other destination inverters.
The standard keypad does not support this feature. The optional multi-function keypad supports it
with Menu #8 in Programming mode.
If the specifications of the source and destination inverters differ, some code data may not be copied
to ensure safe operation of your power system. Whether data will be copied or not is detailed with the
following symbols in the "Data copying" column of the function code tables given below.
Y:
Will be copied unconditionally.
Y1: Will not be copied if the rated capacity differs from the source inverter.
Y2: Will not be copied if the rated input voltage differs from the source inverter.
N:
Will not be copied. (The function code marked with "N" is not subject to the Verify operation,
either.)
If necessary, set up uncopied code data manually and individually.
Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for the digital input and output terminals by setting
the function code data specifying the properties for those terminals. Negative logic refers to the
inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal
(the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally
equivalent to active-OFF signal (the function takes effect if the terminal is opened.) in the negative
logic system. An active-ON signal can be switched to active-OFF signal, and vice versa, with the
function code data setting.
To set the negative logic system for an I/O terminal, enter data of 1000s (by adding 1000 to the data
for the normal logic) in the corresponding function code. Some signals cannot switch to active-OFF
depending upon their assigned functions.
Example: "Coast to a stop" command
BX
assigned to any of digital input terminals [X1] to [X5] using
any of function codes E01 through E05
Function code data
BX
7 Turning
BX
ON causes the motor to coast to a stop. (Active ON)
1007 Turning
BX
OFF causes the motor to coast to a stop. (Active OFF)
