5.2 Overview of Function Codes
This section provides an overview of the function codes frequently used for the FRENIC-Multi series
of inverter.
For details about the function codes given below and other function codes not given below,
refer to the FRENIC-Multi User’s Manual, Chapter 9 "FUNCTION CODES" and the RS-485
Communications User's Manual.
F00 Data Protection
F00 specifies whether to protect function code data (except F00) and digital reference data
(such as frequency command, PID command and timer operation) from accidentally getting
changed by pressing the
/ keys.
Data for F00 Function
0 Disable both data protection and digital reference protection,
allowing you to change both function code data and digital reference data with
the
/ keys.
1 Enable data protection and disable digital reference protection,
allowing you to change digital reference data with the
/ keys. But you
cannot change function code data (except F00).
2 Disable data protection and enable digital reference protection,
allowing you to change function code data with the
/ keys. But you
cannot change digital reference data.
3 Enable both data protection and digital reference protection,
not allowing you to change function code data or digital reference data with the
/ keys.
Enabling the protection disables the / keys to change function code data.
To change F00 data, simultaneous keying of + (from 0 to 1) or + (from 1 to 0)
keys is required.
Even when F00 = 1 or 3, 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. (Refer to
the descriptions of E01 through E05.)
F01, C30 Frequency Command 1 and 2
F01 or C30 sets the source that specifies reference frequency 1 or reference frequency 2,
respectively.
Data for
F01, C30
Function
0 Enable / keys on the keypad.
(Refer to Chapter 3 "OPERATION USING THE KEYPAD.")
1
Enable the voltage input to terminal [12] (0 to r10 VDC, maximum frequency
obtained at r10 VDC).
