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.

Prior to Sequence Program Creation

1.5 Prior to Sequence Program Creation

1.5.1Precautions for sequence program creation

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.

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

REMARKS

•Refer to page 22 for the error codes.

1.5.2Usable main GX Developer functions

zParameter or sequence program read/write

zLadder monitor

zDevice monitor

zDevice test

zAll device memory clear

zRemote RUN/STOP

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.

6

Prior to Sequence Program Creation

1.5.3Sequence program execution key

The sequence program execution key (STOP/RUN) of the PLC is switched by turning off/on the SQ signal.

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.

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.

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)

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.	1

PLC FUNCTION

Prior to Sequence Program Creation

1.5.4Sequence program write

POINT

Sequence program write can be performed in any operation mode.

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.

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.

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.

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)

1.7 Inverter Status Monitoring, Special Registers for Control

You can assign the data for grasping and changing the inverter's operation status to D9133 - D9147 and read/write them from the user sequence. (Refer to page 14 for the list.)

1.7.1Data that can be read at all times

The following data can always be read. They are automatically refreshed every time the END instruction is executed.

(1) Operation monitor

The following data devices are always read-enabled (write-disabled) to allow you to monitor the output frequency, output current and output voltage of the inverter. Note the setting units.

	Device	Name	Setting	Data Example		Data Access Enable
	No.		Unit			Condition
	D9133	Output frequency	0.01Hz	Device data 6000	→ 60.00Hz

Inverter Status Monitoring, Special Registers for Control

<Alarm definition read program example>

The following program reads the latest alarm definition of the inverter to D0.

Alarm definition read request

Stores only the lower 8 bits of error history 1, 2 (D9136) into D0.

(The latest error information is stored into D0.)

<Regarding the error No. and details of the self-diagnostic errors>

During execution of a sequence program, any of the following error No. is stored into D9008 due to an operation error.

At occurrence of a self-diagnostic error, the P.RUN indication (LED) flickers.

	Error No.	Error Name	Details
	10	INSTRCT CODE ERR.	There is an instruction code that cannot be decoded.
			Unusable device is specified.
	11	PARAMETER ERR	Main program capacity setting is over 1k step.
			Unusable function is set.
	22	WDT ERR	Scan time is longer than the time that can be monitored
			by the watchdog timer.
	24	END NOT EXECUTE	END instruction was not executed.

CAUTION

1.For the LD, AND, OR, logical comparison operation and OUT instructions, device checks are always made. For the other instructions (SET, RST, MOV, etc.), however, device checks are made when the execution condition holds.

2.Operation at error stop The outputs (Y) are cleared.

The other devices hold the states prior to an error stop.

When you want to clear them, power off or reset (short RES-SD (0.1s), then open) the inverter.

22

Inverter Status Monitoring, Special Registers

for Control

1.7.2Data that are read by controlling (OFF to ON) the read

command

You can read the operation mode and set frequency of the inverter.

	Device	Name	Read	Write	Data Access
	No.		Command	Completion	Enable Condition
	D9140	Operation mode setting read	Y20	X20	Always
	D9141	Set frequency read (RAM)	Y21	X21
	D9142	Set frequency read (EEPROM)	Y22	X22

Data are stored into the above data devices as soon as the read completion turns from off to on after the read command has turned from off to on.

If the read command remains on, data is not refreshed. (Data is not updated.)

Turn the device off once, then on again to refresh data.

When the speed is set, the speed is either 1r/min or 0.1r/min.

<Set frequency read (EEPROM) program example>

The following program reads the set frequency (E2PROM) to D0.

The following program reads the set frequency (E2PROM) to D0.

Set frequency read (E2PROM) setting request

Stores data to D0 when set frequency read (E2PROM) completion signal turns on.

Turns on set frequency read (E2PROM) command. (Until set frequency read (E2PROM) completion signal turns on)

REMARKS

The read frequency is not the command value of the external signal.

5) Inverter CPU confirms that write command is off and turns off write completion.

4) After confirmation of write completion, write command is turned off.

1.7.3How to write data by controlling (OFF to ON) the write command

You can write the operation mode and set frequency to the inverter, batch-clear the alarm definitions, and clear all parameters.

	Device	Name	Write	Write	Data Access
	No.		Command	Completion	Enable Condition
	D9143	Operation mode setting write	Y23	X23	Pr.79 =0, 2
	D9144	Set frequency write (RAM)	Y24	X24	PU operation mode
		Set frequency write			(PU LED on) or CC-
	D9145		Y25	X25	Link operation mode
		(E2PROM)			(PU and EXT LEDs
					flicker slowly)
	D9146	Alarm definition batch clear	Y26	X26	Always
	D9147	All parameter clear	Y27	X27	As set in Pr. 77

The above data are written as soon as the write completion turns on after the write command has turned from off to on.

(Alarm definition batch clear (D9146) and all parameter clear (D9147) turn on at completion of clear.)

To write the data again, the write command must be turned off once, then on again.
