When terminal command operation is selected (F02 = 1),
simultaneous + keying is disabled.
• Select frequency command 2 or 1 – (Hz2/Hz1)
(Function code data = 11)
Turning the digital input signal (Hz2/Hz1) ON/OFF may
switch the frequency setting method between frequency
command 1 (defined by function code F01) and fre-
quency command 2 (defined by function code C30).
Turning the (Hz2/Hz1) command ON allows the fre-
quency command 2 to be selected.
• Enable editing of function code data from the
keypad – (WE-KP)
(Function code data = 19)
Turning OFF the (WE-KP) command prohibits changing
of function code data from the keypad.
Only when the (WE-KP) command is turned ON, you
may access function code data from the keypad accord-
ing to the setting of function code F00 as listed below.
If (WE-KP) is
set to:
F00 Function
ON
0 Permit editing of function code data
1
Inhibit editing of function code data
except F00
OFF Disabled Inhibit editing of function code data
If the (WE-KP) command is not assigned to any terminal,
the drive will interpret (WE-KP) as being always ON.
• Disable PID control – (Hz/PID)
(Function code data = 20)
Turning the (Hz/PID) command ON/OFF enables or
disables the PID control.
If the PID control is disabled with the (Hz/PID) being
OFF, the drive runs the motor with the frequency manu-
ally set by any of multi-step, keypad, or analog input.
REFERENCE: Refer to the AF-300 Mini User’s Manual,
Chapter 4, Section 4.8 “PID Frequency Command
Generator” for details.
• Switch Normal/Inverse operation – (IVS)
(Function code data = 21)
Turning the (IVS) command ON/OFF switches the output
frequency control between normal (proportional to the
set frequency components) and inverse operation for the
PID process or manually set frequencies. To select the
inverse operation, switch the (IVS) command to ON.
When the PID control is enabled, turning the (IVS)
command ON inverts the PID process control selected
by function code J01. For example, if the PID process
control is normal, turning it ON switches it to inverse, or
vice versa.
• Select link operation – (LE)
(Function code data = 24)
Turning ON the (LE) command selects link operation.
The drive will run the motor with the frequency com-
mand or drive command given via the RS485 communi-
cations facility defined by function code H30.
If the (LE) command is not assigned to any terminal, the
drive will interpret (LE) as being always ON.
• Reset PID integral and differential components
– (PID-RST)
(Function code data = 33)
Turning ON the (PID-RST) command resets the PID
integral and differential components.
• Hold PID integral component – (PID-HLD)
(Function code data = 34)
Turning ON the (PID-HLD) command holds the cur-
rent drive output voltage constant by suppressing an
increase of PID integral component.
• Run forward – (FWD)
(Function code E98/E99 data = 98)
If the (FWD) command is turned ON, the drive runs the
motor forward; if OFF, it decelerates the motor to a stop.
• Run reverse – (REV)
(Function code E98/E99 data = 99)
If the (REV) is turned ON, the drive runs the motor in
reverse; if OFF, it decelerates the motor to a stop.
E20,
E27
Terminal Function for [Y1], [30A], [30B]
and [30C]
E20 to E27 may assign output signals to terminals [Y1]
(transistor switch) and [30A], [30B] and [30C] (mechani-
cal relay contacts) which are general purpose program-
mable output terminals.
These function codes may also switch the logic system
between normal and negative to define the property
of those output terminals so that the drive logic may
interpret either the ON or OFF status of each terminal as
active.
