Function Block Diagram
1.1 Function Block Diagram
How I/O data are transferred to/from the inverter by the built-in PLC function is
explained using function blocks.
(1) I/O data read, write, etc. can be performed by accessing the inverter in the
predetermined method using special relays, special registers, etc.
(2) Operation, parameter read/write, etc. can be performed in accordance with the
created sequence programs (built in the inverter) using input data from the control
input terminals.
With the output signals, output data can be output to outside the inverter from the
control output terminals as not only the inverter's status signals but also pilot lamp
on/off, interlock and other control signals set freely by the user.

common specifications of the inverter.
One point is always necessary for a sequence start (RUN/STOP).
*2 As inverter control is also performed actually, the scan time is approximately 40ms at 500 steps.

Prior to Sequence Program Creation
1.5 Prior to Sequence Program Creation
1.5.1 Precautions for sequence program creation
If any of the instructions (refer to page 103) and devices (refer to page 3) that cannot
be used with the built-in PLC function exists in a sequence program, an instruction
code error occurs at the execution of that instruction.
Error code D9008=10
Operation error step D9010
D9011
1.5.2 Usable main GX Developer functions
zParameter or sequence program read/write
zLadder monitor
zDevice monitor
zDevice test
zAll device memory clear
zRemote RUN/STOP
POINT
•Online change of the sequence program and access to other stations are not
allowed.
In addition, program read/write from other stations and all PLC memory clear
cannot be performed.
•Back up the ladder configured with the protective function of GX Developer.
REMARKS
•Refer to page 22 for the error codes.
CAUTION
Device test ([Online] - [Debug] - [Device test]) of GX Developer can be performed, but if
devices corresponding to control terminal (e.g. STF, STR) signals are tested, the
devices turn on in the sequence but the inverter does not perform the corresponding
operation.

Prior to Sequence Program Creation
1
PLC FUNCTION
1.5.3 Sequence program execution key
The sequence program execution key (STOP/RUN) of the PLC is switched by turning
off/on the SQ signal.
Open (STOP) the SQ signal-SD terminals when writing a sequence program, for
example.
When executing the sequence program, short (RUN) the SQ signal-SD terminals.
Remote run/stop of the built-in PLC function can be executed in any of the following
methods:
• Setting using the built-in PLC function parameter (contact)
• Using GX Developer
• Via CC-Link communication (refer to page 49)
POINT
•For the terminal used for SQ signal input, set "50" in any of Pr.178 to Pr. 189 to
assign the function.
•SQ-SD must be shorted to execute the built-in PLC function.
REMARKS
•The validity limit of the SQ signal can be controlled using Pr.415 Inverter operation lock mode
setting. (Refer to page 43.)
CAUTION
The outputs (Y) are cleared by turning the SQ signal off (STOP) after sequence program
execution (SQ signal on).
The other devices retain the device data prior to STOP. When you want to clear the
remaining device data, power off or reset (short RES-SD for 0.1s, then open) the
inverter.
CAUTION
If the SQ signal is not turned on, the start signal of the inverter is designed to
become valid by the factory setting of Pr.415 Inverter operation lock mode setting.

8
Prior to Sequence Program Creation
1.5.4 Sequence program write
When rewriting the PLC function parameters and sequence program using GX
Developer, check the following:
1)Check that the sequence program execution key is in the STOP position (SQ signal
is off) (refer to page 7).
2)Check that the inverter is at a stop.
3)Check that the communication specification setting parameters (Pr.117 to Pr.124) are
set correctly. If any of these parameters is set incorrectly, communication with GX
Developer cannot be made.
4)Check the PLC series and sequence program capacity in the GX Developer
parameters (refer to page 4).
5) Refer to the GX Developer manual and write the sequence program.
POINT
Sequence program write can be performed in any operation mode.
REMARKS
Check and set the communication specification parameter (Pr. 117 to Pr. 124) using
the parameter unit (FR-PU04/FR-PU07). (Refer to the FR-PU04/FR-PU07
instruction manual for the handling of the FR-PU04/FR-PU07.) GX Developer and
the FR-PU04/FR-PU07 cannot be connected and used simultaneously.
CAUTION
•A sequence program cannot be written with its steps specified. If written,
the sequence program does not run. (The program outside the specified
range is initialized.)
•Do not read the built-in PLC function parameters and sequence program
without writing them to the inverter once using GX Developer. Since the
inverter does not have normal data, always write the built-in PLC function
parameters and sequence program once.
•Since the built-in PLC function parameters and sequence program are
written to the flash ROM, there are restrictions on the number of write times.
(Approximately 100,000 times)

M9008 Self-diagnostic error Turned on by self-diagnosed error.
M9010 Operation error flag Turned on by an instruction execution error.
Turned off when error is removed.
M9011 Operation error flag Turned on by an instruction execution error.
Remains on after normal status is restored.
M9036 Normally ON M9036 and M9037 are turned on and off independently
of STOP or RUN.

RUN status. In other than the STOP status, M9038 is on
for one scan only and M9039 is off for one scan only.
M9037 Normally OFF
M9038 On only for 1 scan after
RUN
M9039 Off only for 1 scan after

1.6.5 Special registers
The special registers are data registers with special applications and therefore data
should not be written to the special registers in the program.

Special registers
D9008 Self-diagnostic
error
Stores the self-diagnosed error number in BIN. (Refer
to page 22 for the error codes.) 22
D9010 Operation error
step
Stores the step number in BIN, at which an instruction
execution error occurred. After that, data is updated
each time operation error occurs.
—
D9011 Operation error
step
Stores the step number in BIN, at which an instruction
error occurred. Since data is stored into D9011 when
M9011 turns from off to on, D9011 data is not updated
unless M9011 is cleared by the user program.
—
D9014 I/O control
method 3 (fixed): Both input and output refreshes —
D9015 CPU operating
status
Stores the operating status of the PLC function.
—
D9016 Program number
Stores the number that indicates which sequence
program is currently in execution.
1 (fixed): Main program (RAM)
—
D9017
Minimum scan
time
(10ms units)
Stores the scan time at every END that is smaller than
D9017 data, i.e. stores the minimum scan time in BIN. —
D9018 Scan time
(10ms units)
Stores and updates the scan time at every END in
BIN. —
D9019
Maximum scan
time
(10ms units)
Stores the scan time at every END that is greater than
D9019 data, i.e. stores the maximum scan time in
BIN.
