1.6 Operations of PLC function (Pr.414, Pr.415,
Pr.498, Pr.1150 to Pr.1199)
I/O information can be read or written by accessing the inverter with special relays, special registers, etc. using
predetermined methods.
It is possible to operate the inverter and read and write parameters using input information from control input terminals
according to created sequence programs (saved in the inverter).
Output signals are also be output from control output terminals, not only as status signals of the inverter but as signals
to turn the pilot lamp ON and OFF, interlock signals, and other control signals set by users as desired.

1.7 Prior to creating sequence programs
1.7.1 Precautions for creating sequence programs
POINTPOINT
• Writing and access to other stations are not possible while a sequence program is running.
Also, reading and writing the program from and to other stations cannot be performed.
• To avoid accidentally erasing the created sequence programs, use FR Configurator2 (Developer) to regularly save the data in
a personal computer, etc.
If a sequence program contains instructions (refer to page 108) or devices (refer to page 10) that cannot be used with the
PLC function, an instruction code error occurs at the execution of that instruction.
Error code SD0 = 4000
Error information SD5 to SD26
Error flag SM0: ON
NOTE
• For the error codes, refer to page 35.
1.7.2 The main functions of FR Configurator2
(Developer)
• Reading and writing parameter and sequence programs
• Ladder monitor
• Device batch monitor
• Present value change
• Remote RUN/STOP
NOTE
• Present values can be changed using FR Configurator2 (Developer) ([Debug] -> [Present value change]). Even if changes
are made to the devices corresponding to the control terminal signals (STF, STR, etc.), such changes are not applied to the
inverter operation. (Device present values of the sequence programs are changed.)

14 PLC Function
Prior to creating sequence programs
1.7.3 Sequence program execution
 Reset the inverter after configuring settings to enable the PLC function.
PLC function operation selection (Pr.414)
• To enable the PLC function, set "1" or "2" in Pr.414 PLC function operation selection. When Pr.414 = "1", the command
source for the sequence start (SQ) signal is determined by Pr.338 Communication operation command source. When
"2" is set in Pr.414, SQ signal from the external input terminal is valid regardless of the setting of the Pr.338.
• Switch the execution key (RUN/STOP) of the sequence program by turning the SQ signal ON/OFF. The sequence program
can be executed by turning the SQ signal ON. To input the SQ signal, set "50" in any of Pr.178 to Pr.189 (input terminal
function selection) to assign the function to a terminal.
• Remote RUN/STOP of the PLC function can be executed in any of the following methods:
• Using the PLC function parameters (contact)
• Using FR Configurator2 (Developer)
• Via CC-Link communication (refer to page 58.)
NOTE
• Turn OFF (STOP) the SQ signal when creating a sequence program.
• The RUN state output (Y) is internally stored and all outputs (Y) are turned off by turning the SQ signal OFF (STOP) after
sequence program execution (SQ signal ON).
The other devices retain the data prior to STOP. To clear the remaining device data, power OFF or reset (RES signal ON (0.1
s)OFF) the inverter.
Inverter operation lock mode setting (Pr.415)
• When "1" is set in Pr.415 Inverter operation lock mode setting, the inverter can be operated only when the sequence
program is set to the "RUN" status. By changing the PLC program status from RUN to STOP during inverter operation, the
motor decelerates to stop.
POINTPOINT
• To run the inverter without using the PLC function, set Pr.415 = "0" (initial value) (the start signal of the inverter is enabled).
NOTE
• This parameter cannot be written during inverter operation, regardless of the Pr.77 setting.
• During automatic operation using SD1148 (or SM1200 to SM1211) in the sequence program, the inverter stops operation if
the sequence program is in the STOP state while Pr.415 = "1". However, when Pr.415 = "0", the device data is retained and
the operating status does not change (the inverter continues operation) even if the sequence program is in the STOP state.
• Pr.415 setting is also enabled for the start signals of the operation panel.

The start signal of the inverter is enabled only when
the sequence program is in RUN state. (The SQ signal
is ON.)
When the sequence program is in STOP state (the SQ
signal is OFF), the inverter will not start even if the
start signal STF or STR is turned ON. (If the state is
changed from RUN to STOP during operation, the
inverter decelerates and stops.)

1.7.4 Setting the communication parameter
POINTPOINT
• For RS-485 communication between the inverter and FR Configurator2, communication cannot be established when the
inverter communication parameter settings and the FR Configurator2 communication settings differ.
• Set "9999" in Pr.122 PU communication check time interval for communication using the PU connector, and set "9999"
in Pr.336 RS-485 communication check time interval for communication with RS-485 terminals.
• Use the same settings for the inverter communication parameters (Pr.118 to Pr.120, Pr.124, Pr.332 to Pr.334, and Pr.341)
and the FR Configurator2 communication settings.
• Initial values are shown below.
NOTE
• Use the operation panel to change the settings of the inverter parameters.
The operation panel and FR Configurator2 (personal computer) cannot be connected to the PU connector simultaneously.
• For details on each inverter communication parameter, refer to the Instruction Manual (Detailed) of the inverter. For the
setting method of the [Detailed setting] of the [System setting] window of FR Configurator2, refer to the Instruction Manual of
FR Configurator2.
• Parameter clear/All parameter clear clears communication parameter settings and may disable the communication with FR
Configurator2 (Developer).

1.7.5 Writing sequences programs
POINTPOINT
• Sequence programs can be written in any operation mode (External operation mode, PU operation mode and Network
operation mode). For the operation modes, refer to the Instruction Manual (Detailed) of the inverter.
Check the following points when rewriting the PLC function parameters and sequence programs using FR Configurator2
(Developer):
• The sequence program execution status is in the STOP (SQ signal OFF) (refer to page 14).
• The inverter is stopped.
• The communication specifications setting parameters (Pr.117 to Pr.124) are correctly set. Communication with FR
Configurator2 (Developer) is not possible if these parameter setting values are incorrect.
• The PLC series setting and sequence program capacity are correctly set with FR Configurator2 (Developer) parameters.
(Refer to page 11.)
Refer to the FR Configurator2 manual and write sequence programs.
NOTE
• A sequence program cannot be written with its steps specified. The sequence program does not run if written in this way.
(The program outside the specified range is initialized.)
• To read the PLC function parameters and sequence programs from the inverter, such information must be written to the
inverter using FR Configurator2 (Developer) in advance. Always write the PLC function parameters and sequence program at
least once as the inverter does not have valid data.
• There is a limitation on the number of times writing can be done (approximately 100,000 times) as the PLC function
parameters and sequence program are written to the flash memory.
• A program with more than 6k steps (24k bytes) cannot be written.
