4.2 Details of Function Codes
This section provides the details of the function codes. The descriptions are, in principle, arranged in the order of
function code groups and in numerical order. However, highly relevant function codes are collectively described where
one of them first appears.
4.2.1 Fundamental Functions
F00
Data Protection
F00 specifies whether to protect function code data (except F00) and digital reference data (such as frequency
command and PID command) from accidentally getting changed by pressing the
/
keys on the keypad.

*Only F00 data can be modified with the keypad, while all other function codes cannot.
To change F00 data, simultaneously press "
+
" (from 0 to 1) or "
+
" (from 1 to 0) keys.
For similar purposes,
WE-KP
, a signal that enables editing of function code data from the keypad is provided as a
terminal command for digital input terminals. (Refer to the descriptions of E01 through E07, data = 19)
The relationship between the terminal command
WE-KP
and F00 data are as shown below.

• If you mistakenly assign the terminal command
WE-KP
, you can no longer edit or modify function code
data. To undo this temporarily turn this
WE-KP
-assigned terminal ON and reassign the
WE-KP
to a
correct command.
•
WE-KP
is only a signal that allows changing function code data, so it does not protect the frequency
settings or PID command specified by the
and
keys.
Even when F00 = 1 or 3, function code data can be changed via the communications link.
F01
Frequency Command 1 (Related parameters listed here)
F18 (Bias, Frequency command 1)
C30 (Frequency Command 2)
C31 to C35 (Analog Input Adjustment for [12])
C36 to C39 (Analog Input Adjustment for [C1])
C41 to C45 (Analog Input Adjustment for [V2])
C50 (Bias (Frequency command 1), Bias base point)
H61 (
UP/DOWN
Control, Initial frequency setting) d59, d61 to d63 (Command (Pulse Rate Input))
F01 or C30 sets a command source that specifies reference frequency 1 or reference frequency 2.

Enable
/
keys on the keypad.
[ 1 ]
1
Enable the voltage input to terminal [12] (0 to
10 VDC, maximum frequency obtained at
10 VDC).
[ 2 ]
2
Enable the current input to terminal [C1] (+4 to +20 mA DC, maximum frequency obtained at +20 mA
DC). (SW5 on the control PCB should be turned to the C1 side (factory default).)
3
Enable the sum of voltage (0 to
10 VDC) and current inputs (+4 to +20 mA DC) given to terminals [12]
and [C1], respectively. See the two items listed above for the setting range and the value required for
maximum frequencies. (SW5 on the control PCB should be turned to the C1 side (factory default).)
Note: If the sum exceeds the maximum frequency (F03), the maximum frequency will apply.
5
Enable the voltage input to terminal [V2] (-10 to ±10 VDC, maximum frequency obtained at ±10 VDC).
(SW5 on the control circuit board should be turned to the V2 position (factory default).)
7
Enable
UP
and
DOWN
commands assigned to the digital input terminals.
The
UP
command (any of E01 to E07 = 17) and
DOWN
command (any of E01 to E07 = 18) should be
assigned to any of digital input terminals [X1] to [X7].
For details, refer to the descriptions of E01 through E07.

11
Enable a digital input interface card (option).
(For details, refer to the Digital Input Interface Card Instruction Manual.)
－
12
Enable the "Pulse train input"
PIN
command assigned to digital input terminal [X7] (E07 = 48), or a PG
interface card (option).
