DriveProgramming User’s Manual (I580-E2)

8-1 Troubleshooting

This section describes the program operation at the time of error occurrence, the error codes that are specific to the DriveProgramming, and the remedies for them.

Basically, even if the inverter detects a trip during the DriveProgramming operation, the operation is continued. However, if any of E43 to E45 trips related to the DriveProgramming is detected, the operation is stopped. Or, with the “on trip goto” command, the program can jump to other process after a trip occurred.

Precautions for Safe Use

When execution of the DriveProgramming program is stopped, the status before the program stop is retained for multi-function outputs controlled by the DriveProgramming.

For this reason, the wiring must be made so that the stop of the DriveProgramming program in the inverter can be detected by the DriveProgramming start signal and the alarm (trip) signal, and the inverter's peripheral devices can be stopped safely.

Safety Precautions

Drive Programming User’s Manual (I580-E2)

WARNING

Turn off the power supply and implement wiring correctly.

Not doing so may result in a serious injury due to an electric shock.

Wiring work must be carried out only by qualified personnel.

Not doing so may result in a serious injury due to an electric shock.

Do not change wiring and slide switches, put on or take off Operator and optional devices, replace cooling fans while the input power is being supplied.

Doing so may result in a serious injury due to an electric shock.

Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire.

(200-V class: type-D grounding, 400-V class: type-C grounding)

Do not remove the terminal cover during the power supply and 10 minutes after the power shut off.

Doing so may result in a serious injury due to an electric shock.

Do not operate the Operator or switches with wet hands.

Doing so may result in a serious injury due to an electric shock.

Inspection of the inverter must be conducted after the power supply was turned off.

Not doing so may result in a serious injury due to an electric shock.

The main power supply is not necessarily shut off even if the emergency shut off function is activated. Do not touch the inverter fins, braking resistors and the motor, which become too hot during the power supply and for some time after the power shut off.

Doing so may result in a burn.

Caution

Do not connect resistors to the terminals (1, P/2, N/) directly.

Doing so might result in a small-scale fire, heat generation, or damage to the unit.

Install a stop motion device to ensure safety. Not doing so might result in a minor injury.

(A holding brake is not a stop motion device designed to ensure safety.)

Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit. Configure a sequence that enables the inverter power to turn off when unusual over eating is detected in the braking resistor/regenerative braking unit. The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or other property. Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring.

Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the Inverter capacity on the power supply side.

Not doing so might result in damage to property due to the short circuit of the load. Do not dismantle, repair or modify the product.

Doing so may result in an injury.

Precautions for Safe Use

Drive Programming User’s Manual (I580-E2)

Precautions for Safe Use

• If a parameter is set incorrectly when starting up, adjusting, maintaining, or replacing, an unexpected operation may occur. Perform the operation after enough confirmation.

• If the Drive Programming stops during multi-function output, the output status is held. Take safety precautions such as stopping peripheral devices.

• If the clock command is used in the Drive Programming, an unexpected operation may occur due to weak battery of the LCD Digital Operator.

Take measures such as detecting a weak battery by a check that the clock data returns to the initial setting and stopping the inverter or programs.

When the LCD Digital Operator is removed or disconnected, Drive Programming is in a waiting status by the clock command.

• When using the Drive Programming, check that program data is downloaded successfully before starting operation.

Drive Programming User’s Manual (I580-E2)

1-1 Overview of Drive Programming

The Drive Programming is the simple sequence function built into the inverter.

To create sequence programs and check their status, you use the Inverter/Servo supporting tool, CX-Drive.

Transfer (download) the created programs to the 3G3MX2/3G3RX Series Inverter so that the stand-alone inverter can perform simple sequence control.

The Drive Programming has the following features.

• The Drive Programming supports both flowchart and text language method programming.

• You can create a program divided into up to five tasks.

• Five tasks can be processed in parallel.

• It is possible to execute user programs externally by settings of multi-function input terminals.

• You can use the multi-function I/O terminals by allocating them to the parameters.

• The Digital Operator enables you to change the settings of the frequency, acceleration/deceleration time, and other parameters (variables) that require on-site adjustment by specifying the user parameters (P100 to P131), without connecting the computer.

• Because user programs are stored in the internal EEPROM of the inverter, you can start a program immediately after the inverter power supply is turned on.

• The optional LCD Digital Operator (Model: 3G3AX-OP05) has a built-in clock function. By purchasing and connecting the LCD Digital Operator, you can create programs that use the LCD Digital Operator’s clock function.

MX2

You cannot connect the 3G3MX2 Series Inverters with the LCD Digital Operator (Model: 3G3AX-OP05). Therefore, the clock function is not available.

Precautions for Safe Use

If the clock command is used in the Drive Programming, an unexpected operation may occur due to weak battery of the LCD Digital Operator.

Take measures such as detecting a weak battery by a check that the clock data returns to the initial setting and stopping the inverter or programs.

When the LCD Digital Operator is removed or disconnected, Drive Programming is in a waiting status by the clock command.

The following table shows the main functions of the Drive Programming Editor available in CX-Drive.

3 Operation Procedure for Drive Programming

Drive Programming User’s Manual (I580-E2)

3-1 Operation Procedure

You can create user programs in the flowchart method or the text language method. It is also possible to select between two methods for each task or subroutine.

Use the Drive Programming Editor in CX-Drive to input user programs.

Drive Programming Editor consists of the Drive Programming area, Toolbox window, Block Parameter window, Properties window, and Output window.

• In the Drive Programming area, you can create programs in the flowchart method or text language method.

• The Toolbox window displays the command blocks in categories.

• In the Block Parameter window, you can set parameters that are used when the program execution is started.

• In the Properties window, you can edit the properties of a block which is currently selected in flowchart.

• The Output window displays compilation errors and warnings after a compilation is finished.

Programs created in the Drive Programming area are compiled and converted into the final "programs after compilation". Then, the programs are transferred (downloaded) to the inverter.

The compiler performs checks for the items such as program validity, program syntax, parameter input limitation and maximum number of steps. If there is any input which is not permitted, the compilation is stopped and an error message is displayed.

The compiler also performs the operations as shown below, and creates the final "programs after compilation". Therefore, if you transfer (upload) the program once saved in the inverter to the CX-Drive, the program which is read out is the "program after compilation". While its operation is the same as before compilation, its form and contents are partially different.

• Converts flowchart programs to text programs.

• Automatically converts the label names specified in the program to the following names: label 1, label

2...

• Deletes comments entered in the program.

• Deletes alias definitions and converts specified names to the same ones as before definition.

• Deletes region definitions and converts forms to the same ones as before definition.

• Deletes all spaces and blank lines in the program.

• Performs validity checks.

Precautions for Correct Use

• The specified comments, alias definitions and region definitions are deleted when a compilation is performed for program conversion or transferring (downloading) to the inverter.

To save those contents, save the program before you execute program conversion or you transfer (download) the program to the inverter.

You can save the program by saving the whole project in the CX-Drive or export file of the program.

• Program verification means a comparison between "program after compilation" and the program inside the inverter. Therefore, comments, alias definitions, region definitions, etc. are not verified.

Drive Programming User’s Manual (I580-E2)

Download compiled programs to the inverter and save them in the EEPROM of the inverter.

You can start programs saved in the EEPROM after turning on the power supply, without using the tool (CX-Drive).

Set Drive Programming Function Selection (A017) to Enabled (01 or 02) to use the Drive Programming function. You can change the Drive Programming Function Selection (A017) even when the operation is in progress.

*1. Multi-function input terminals for MX2 are S1 to S7, and for RX are S1 to S8.

When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via multi-function input PRG terminal), set one of Multi-function Input S1 to S7/S8 Selection to 82 (PRG). The program is started when the multi-function input terminal set to PRG is turned ON. The program execution continues while the PRG terminal is ON and stops when the terminal is turned OFF.

When the Drive Programming Function Selection (A017) is set to 02, the program is started right after the setting is completed. The program will also be started automatically at next power on.

Once the program reaches “end” command after it was started and a series of processes was completed, the program is not executed unless it is restarted.

To repeat the program, create a loop program so that the program does not reach “end” command.

The downloaded Drive Programming program is saved in the EEPROM of the inverter. Therefore, after downloading, you can start the program without using the support tool.

3-3 Program Structure

3-3-1 Tasks

3-3 Program Structure

In the Drive Programming for 3G3MX2/3G3RX Series Inverter, you can create a maximum of five tasks.

The created tasks are processed in parallel.

By dividing one application into several processes and allocating them to multiple tasks, you can adjust execution condition, execution order, etc. for each process. Furthermore, parallel task processing can provide shorter processing time.

Task is a unit of program executed in the Drive Programming.

For 3G3MX2/3G3RX Series Inverter, you can create a program which consists of up to five tasks.

• All tasks are started simultaneously.

• In the order of task from 1 to 5, one command of each task (one line of the "program after compilation") is executed in 2-ms processing time.

• All function variables such as user parameters are shared among the tasks. For transmission of information between tasks, use the user parameters, internal user contacts, etc.

• At the end of 2-ms processing time, the operation result of each task is reflected to the inverter operation, external output, etc. At the same time, the status of the inverter and external input terminals, etc. are read in.

• When the "end" command is executed, the task is completed and waits for the next start.

Subroutine is a separated program processing executed only when it is called.

Subroutines are useful to organize your program into parts that you can execute multiple times in the same task or reuse in other programs.

In the Drive Programming, it is necessary to insert subroutines into each task. They cannot be shared among the tasks.

It is possible to call a subroutine from another subroutine (nesting).

However, the maximum nesting of subroutines is eight levels.

UP to five tasks are started simultaneously, and one command of each task (one line of the "program after compilation") is executed in 2-ms processing time. The following figure Programs After Compilation (Example) shows the flow of the program processing.

• All tasks are started simultaneously.

• In the order of task from 1 to 5, one command of each task (one line of the "program after compilation") is executed in 2-ms processing time.

• All function variables such as user parameters are shared among the tasks.

• As shown in Task 1, if a subroutine is called by the “call” command, the statement of the subroutine will be executed from the next step of processing.

Drive Programming User’s Manual (I580-E2)

• As shown in Task 2, if the “end” command is executed, the task will be finished and wait for the next start.

• As shown in Task 3, if the “wait” command is executed, the task will be repeatedly executed until a certain condition is met.

• As shown in Task 4, if you create a loop by using the “goto” command, the task process will be continuously repeated.

• As shown in Task 5, if the “on trip goto” command is executed once, the processing data will be stored in the inverter.

The program jumps to the “goto” destination immediately after a trip occurred.

3 Operation Procedure for Drive Programming

Drive Programming User’s Manual (I580-E2)

3-3 Program Structure

3-3-4 Drive Programming Start/Stop and Task Operation

You set the start/stop method of the Drive Programming programs in the Drive Programming Function Selection (A017).

 Start

• When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via multi-function input PRG terminal):

The program starts when the multi-function input terminal set to PRG is turned ON.

• When the Drive Programming Function Selection (A017) is set to 02 (Enabled: Start/stop at power on/off):

The program starts when the power supply for the inverter is turned ON.

 Stop

• When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via multi-function input PRG terminal):

The program stops when the multi-function input terminal set to PRG is turned OFF.

• When the Drive Programming Function Selection (A017) is set to 02 (Enabled: Start/stop at power on/off):

The program stops when the power supply for the inverter is turned OFF.

Also, regardless of the A017 setting, the Drive Programming program stops if any of E43 to E45 trips is detected due to a program error, or when the “end” command is executed in all tasks.

Precautions for Safe Use

When the Drive Programming program is stopped, the status before the program stop is retained for multi-function outputs controlled by the Drive Programming

For this reason, configure the system so that the stop of the Drive Programming program in the inverter can be detected by the Drive Programming start signal and the alarm (trip) signal, and the inverter's peripheral devices can be stopped safely.

Precautions for Correct Use

The following are the status of function variables when the Drive Programming program is stopped. Take necessary measures in consideration of each status.

• For the multi-function outputs (the inverter's actual output terminals), the status before the program stop is retained.

However, the output terminals that are not set to MO1 to MO6 (general-purpose outputs of the Drive Programming) operate as the inverter's normal multi-function outputs.

• When the Drive Programming function is selected for the frequency reference, acceleration/deceleration time or analog outputs, the set values for these functions before the program stop are retained.

• The data of the user parameter variables, internal user variables and internal user contacts before the program stop is retained.

• The status of the inverter's actual input terminals such as the multi-function and analog input terminals is not retained but always updated.

• The data of the multi-function output variables (function bits such as RUN, FA1 and AL) and inverter monitor variables is not retained but always updated according to the status of the inverter.

• Only the Drive Programming's multi-function input variables (function bits such as FW, RV and CF1) and timer variables are cleared at the same time as the program stop, and all data are changed to zero.

3-3-4 Drive Programming Start/Stop and Task Operation

3 Operation Procedure for Drive Programming

3 - 16

Drive Programming User’s Manual (I580-E2)

When the Drive Programming function is started/stopped through the CX-Drive, the value of the inverter parameter, Drive Programming Function Selection (A017) is temporarily changed to 02 (start) or 00 (stop) only in the RAM data.

Take the following measures after you started/stopped the Drive Programming function through the CX-Drive.

• Turn ON the power supply for the inverter again and return the value of A017 to that saved in the EEPROM.

• Do not perform the following EEPROM saving operations before you turn ON the power supply for the inverter.

• Transferring (downloading) a part of parameters from the CX-Drive.

• Issuing the “enter” command via the Modbus communication or a communication option.

When the Drive Programming program is started, five tasks are started simultaneously.

If you create a loop construction in a task by using commands such as the “goto”, the task will repeat the loop after it is started.

When the Drive Programming program is stopped, five tasks are stopped simultaneously.

If the program is stopped while the Motor is running, the Motor will be stopped according to the setting for the Stop Selection (b091) (deceleration stop or free-run stop).

The task operations for different settings are shown below.

3-3-5 Drive Programming Restart

You can restart the stopped program by performing the following operations. When the program is restarted, all tasks are started simultaneously from the beginning.

• When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via multi-function input PRG terminal): a reset input via the control circuit terminal while the PRG terminal is ON, or turning ON the PRG terminal again.

• When the Drive Programming Function Selection (A017) is set to 02 (Enabled: Start/stop at power on/off): a reset input via the control circuit terminal, or turning ON the power supply for the inverter again.

Precautions for Correct Use

• You cannot restart the Drive Programming by pressing the STOP/RESET key of the Digital Operator or the LCD Digital Operator (optional). Set one of the Multi-function input terminals (MX2: S1 to S7/RX: S1 to S8) to 18 (RS: Reset) and turn ON that terminal.

• To restart the Drive Programming by reset input, set the Reset Selection (C102) to the value other than 03 (Trip reset only). You cannot restart the Drive Programming when 03 (Trip reset only) is set.

• When the Reset Selection (C102) is set to 00 (Trip reset at power-on) or 01 (Trip reset at power-off), the Drive Programming can be restarted by a reset input even when there is no trip.

In the flowchart program method, a unit of display is called "Block".

You create a program by placing more than one block in the area and setting interaction between them.

In a flowchart program, when a program is compiled successfully, an icon with a white arrow in a green circle highlights the starting point of each flowchart task.

Also, after the program is compiled successfully, the block number will appear on the upper left of each block.

Block numbers are the consecutive numbers starting with "0". A block number is given to each block of the whole program.

The numbers do not match the line numbers of the program converted to text.

The Output window will indicate if the program is compiled successfully. For programs compiled with errors, a red icon with an exclamation mark identifies the erroneous blocks in the flowchart program. Placing the mouse on the error icon displays the compile error, which you can see in the Error List in the Output window.

If you right-click on a blank area in the flowchart, a popup menu will be displayed. It allows you to paste blocks that you copied last, or to select all the blocks.

Executing Programs (Drive Programming Function Selection)

There are two ways to execute programs after you transferred (downloaded) them to the inverter as described below.

Executing via CX-Drive is a convenient way to debug the created program.

Use icon in the toolbar of the Drive Programming Editor to start the program. To stop the program,

use icon. Note that executing program via the CX-Drive is enabled only when the following conditions are met.

• When the CX-Drive is connected to the inverter.

Once the program is started, it does not stop even if the CX-Drive is disconnected. Therefore, when executing the program, make sure that you can stop the inverter immediately by turning off the power supply, etc.

• When the program in the CX-Drive matches the program in the inverter through verification after compilation.

• The program stop is executed regardless of the program in the CX-Drive.

You execute the program by setting the inverter parameter, the Drive Programming Function Selection (A017).

Once the program reaches "end" command after a series of processes was completed, the program is not executed unless it is restarted.

To repeat the program, create a loop program so that the program does not reach “end” command.

If the Drive Programming function is stopped while the Motor is running, the Motor will be stopped according to the setting for the Stop Selection (b091) (deceleration stop or free-run stop).
