5. Function Codes
5.1 Function Code Tables
Function codes enable the AF-300 Mini series of drives
to be set up to match your system requirements.
Each function code consists of a 3-character string. The
first is a letter identifying the group and the following two
are numerals that defining each individual code in the
group. Function codes are classified into seven groups:
Fundamental Functions (F codes), Extension Terminal
Functions (E codes), Control Functions of Frequency (C
codes), Motor Parameters (P codes), High Performance
Functions (H codes), Application Functions (J codes),
and Link Function (y codes). To determine the property
of each function code, set data to the function code.
Changing, reflecting, and saving function code data
when the motor is running
Function codes are indicated by the following, based on
whether they can be changed or not while the motor is
running:
– Function codes marked with N (in the “Change
when running” column of the function code tables
given below): The data of these codes cannot be
changed when the motor is running.
– Function codes marked with Y: The data for these
codes can be changed with the and keys
regardless of whether the motor is running or not.
Pressing the key will make the change effective
and save it into the drive’s memory.
– Function codes marked with Y*: The difference
from function codes marked with Y and others is
that if the data for these codes is changed, the ef-
fect is immediate. However the change is not saved
into the drive’s memory. To save the change, press
the key. If you press the key to exit the current
state without pressing the key, then the changed
data will be discarded and the previous data will be
restored for the current drive operation.
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 func-
tion codes that specify properties for those terminals.
Negative logic refers to inverted ON/OFF (logical value 1
(true)/0 (false)) state of input or output signal. An ON-ac-
tive signal (the function takes effect for the ON signal.)
in the normal logic system is functionally equivalent to
OFF-active signal (the function takes effect for the OFF
signal.) in the negative logic system.
To set the negative logic system for an I/O signal
terminal, display data as 1000s (by adding 1000 to the
data for the normal logic) in the corresponding function
code and then press the key.
For example, if a coast-to-stop command (BX: data =
7) is assigned to any one of digital input terminals [X1]
to [X3] by setting any of function codes E01 through
E03, then turning (BX) ON will make the motor coast
to a stop. Similarly, if the coast-to-stop command (BX:
data = 1007) is assigned, turning (BX) OFF will make the
motor coast to a stop.
Restriction of data displayed on the LED monitor
Only four digits can be displayed on the 4-digit LED
monitor. If you enter more than 4 digits of data valid for
a function code, any digits after the 4th digit of the set
data will not be displayed, however they will be pro-
cessed correctly.
