5.2 Overview of Function Codes
This section provides an overview of the function codes frequently used for the FRENIC-Eco series of inverter.
 For details of the function codes given below and other function codes not given below, refer to the
FRENIC-Eco User’s Manual, Chapter 9 "FUNCTION CODES."
F00 Data Protection
Specifies whether function code data is to be protected from being accidentally changed by
keypad operation. If data protection is enabled (F00 = 1), the
/ key operation to change
data is disabled so that no function code data except F00 data can be changed from the keypad.
To change F00 data, simultaneous keying of
+ (from 0 to 1) or
+ (from 1 to 0) keys
is required.
Even when F00 = 1, function code data can be changed via the communications link.
For similar purposes, (WE-KP), a signal enabling editing of function code data from the
keypad is provided as a terminal command for digital input terminals. For details, refe
r
to function codes E01 to E05, E98 and E99.
F01
C30
Frequency Command 1
Frequency Command 2
F01 selects the source of reference frequency 1 (F01) or reference frequency 2 (C30) for
specifying the output frequency of the inverter (motor speed).
Data for
F01, C30
Function
0 Enable / keys on the keypad. (Refer to Chapter 3 "OPERATION
USING THE MULTI-FUNCTION KEYPAD.")
1 Enable the voltage input to terminal [12] (0 to 10 VDC, maximum frequency
obtained at 10 VDC).
2 Enable the current input to terminal [C1] (4 to 20 mA DC, maximum frequency
obtained at 20 mA DC).
3 Enable the sum of voltage and current inputs to terminals [12] and [C1]. See the
two items listed above for the setting range and the value required for maximum
frequencies.
Note: If the sum exceeds the maximum frequency (F03), the maximum
frequency will apply.
5 Enable the voltage input to terminal [V2] (0 to 10 VDC, maximum frequency
obtained at 10 VDC).
7 Enable (UP) and (DOWN) commands assigned to the digital input terminals.
Assign (UP) command (data = 17) and (DOWN) command (data = 18) to the digital
input terminals [X1] to [X5].
Certain source settings (e.g., communications link and multistep frequency) have
priority over the one specified by F01. For details, refer to the block diagram in the
FRENIC-Eco User’s Manual, Chapter 4, Section 4.2 "Drive Frequency Command
Generator."
