5.2 Overview of Function Codes
This section provides an overview of the function codes frequently used for the FRENIC-Mini series
of inverter.
For details about the function codes given below and other function codes not given below,
refer to the FRENIC-Mini User’s Manual, Chapter 9 "FUNCTION CODES" and the RS-485
Communication User's Manual.
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),
or 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
+
keys is required.
F01, C30
Frequency Command 1 and 2
F01 or C30 sets the source that specifies reference frequency 1 or reference fre-
quency 2, respectively.
Set F01 to: To do this
0
Enable the and keys on the built-in keypad.
(Refer to Chapter 3 "OPERATION USING THE 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
maximum frequencies.
Note: If the sum exceeds the maximum frequency, the maximum
frequency will apply.
4
Enable the built-in potentiometer (POT). (Maximum frequency
obtained at full scale of the POT)
• There are other frequency command means (such as the communi-
cations facility, multi-frequency, etc.) with higher priority than that of
F01. Refer to the FRENIC-Mini User's Manual, Chapter 4, Section 4.2
"Drive Frequency Command Generator" for more details.
• For frequency commands by terminals [12] (voltage) and [C1] (cur-
rent) and by the built-in potentiometer, setting the gain and bias
changes the relationship between those frequency commands and the
drive frequency to enable matching your system requirements. Refer
to function code F18 for details.
• For the inputs to terminals [12] (voltage) and [C1] (current), low-pass
filters can be enabled. Refer to the FRENIC-Mini User's Manual,
Chapter 9, "FUNCTION CODES" for details.
In addition to "F01 Frequency set 1," "C30: Frequency set 2" is available. To switch
between them, use the terminal command
Hz2/Hz1
. For details of the
Hz2/Hz1
,
refer to "E01 to E03, E98, and E99: Command Assignment to Terminals [X1] to [X3],
[FWD], and [REV]."
