6.2 Function Code Tables
The following descriptions supplement those given in the function code tables on page 6-3 and
subsequent pages.
„ Changing, validating, and saving function code data when the inverter is running
Function codes are indicated by the following based on whether they can be changed or not when the
inverter is running:
Notation Change when running Validating and saving function code data
Y* Possible
If the data of the codes marked with Y* is changed with /
/ / keys, the change will immediately take effect;
however, the change is not saved into the inverter's memory.
To save the change, press the
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
/ / / keys, the change will not take effect.
Pressing the key will make the change take effect and save
it into the inverter's memory.
N Impossible —
„ Copying data
The keypad is capable of copying the function code data stored in the inverter's memory into the
keypad's memory (PRG > 2(Function Code) > 4(Data Copy)). With this feature, you can easily
transfer the data saved in a source inverter to other destination inverters.
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 on page 6-3 and
subsequent pages.
Y: Will be copied unconditionally.
Y1: Will not be copied if the rated capacity differs from the source inverter.
N: Will not be copied. (The function code marked with "N" is not subject to the Verify operation,
either.)
„ Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for the programmable, 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. Active-ON signals can be switched to active-OFF signals, and
vice versa, with the function code data setting, except some signals.
To set the negative logic system for an input or output terminal, enter data of 1000s (by adding 1000 to
the data for the normal logic) in the corresponding function code.
Example: "Coast to a stop" command
BX assigned to any of digital input terminals [X1] to [X7] using
any of function codes E01 through E07.
Function code data Description
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)
