3- Drive Programming Editor
Drive Programming Editor allows the user to design drive programs in an intuitive way. CX-Drive
provides a way to create drive programs, compile them, transfer them to and from the drive, start and
stop their execution, and other related tasks.
You can open this function by clicking on Drive Programming in the workspace of a drive which
supports it, or selecting Program | Program Editor from the Drive menu, or with the CX-Drive toolbar
button .
Please create a new CX-Drive File by clicking on the menu File | New. The New Drive window will
appear (Image 1). Select the Drive Type and press OK button. Then it will appear on the Workspace
(Image 2).

3-1 Saving and loading programs
A drive program is automatically saved when the drive document which contains it is saved.
When a CX-Drive document is opened, the drive program which it contains, if any, is automatically
loaded. You can display it by opening the Program Editor.
Alternatively, you can export a drive program, to save it independently of other drive information. To
do so, use the Program | Export Program command in the Drive menu. Enter the name of the file to be
used. The file will be saved with extension driveprogram.
A drive program can be imported with the Program | Import Program command in the Drive menu.
3-2 Editor
The Program Editor is the main window of the Drive Programming function.
The window area consists of a toolbar with common commands, and a designer area where the
program is displayed as a text.

Description
New task (Flowchart) It allows creating a new Flowchart task for the program, up to the
maximum number of tasks allowed. Tasks are parts of the
program which are executed independently of each other.
New Task (Text) It allows creating a new Text task for the program, up to the
maximum number of tasks allowed. Tasks are parts of the
program which are executed independently of each other.
New Sub
routine
(Flowchart) It allows creating a new Flowchart subroutine. A subroutine is a
part of the program which is called from a task.

Transfer to Drive It compiles the program and, if there are no errors, transfer it to the
drive.
Transfer from Drive
It transfers the program from the drive to the Program Editor.
Start It starts the program in the drive. CX-Drive will first compare it with
the program currently being edited, to make sure that they are the
same. If they differ, the program will not be started.
Stop It stops the program in the drive. This action is done regardless of
whether the program in the drive is the same that in the program
designer.

To change one block command argument, place the cursor at its row and click on the edition box to
the right of its name.
▪If the block argument has options, a second click of the mouse will unfold the available options for
you to select.
▪If the block argument does not have options, clicking on its current value will enable you to change it
by typing a new one. CX-Drive will warn you if the value exceeds the valid range.
If the block argument can have both an option and a custom value, clicking on the unfold sign at the
right of the cell will unfold the available options, whereas clicking anywhere in the cell text, you will be
able to edit it.

It shows the compilation errors and warnings of the currently edited drive program after it is compiled.
Errors will prevent the program to be correctly compiled. Warnings will allow compilation, but advise
customer of abnormal conditions.
· The Error(s) button toggles displaying error in the list.
· The Warning(s) button toggles displaying warnings in the list.
· The Message(s) button toggles displaying informative message in the list.
Messages in the list show the following information:
· Date: The date and time when the error was generated.
· Component: Identifies the element with an error.
· Description: The text of the error or warning message.
The list is automatically cleared every time a Compile is done.
3-10 Creating a program with Flowchart Editor
Follow the steps described below to create a drive program.
1. Open the Program Editor. The Drive Programming auxiliary windows (Toolbox, Block Parameters,
Properties and Error List) will be displayed automatically.
2. Select on the menu “New Tab” New Task (flowchart) or New Subroutine(flowchart).
3. Drag each block of the program from the Toolbox window to the Flowchart Program Editor.
4. After dragging a block, edit its properties by clicking on it and edit the arguments in the Properties
window.
5. Connect the blocks accordingly.
6. Edit the drive program variables in the Block Parameters window.
7. You may now compile the program, transfer it to the drive, export it, etc.
Alternatively, you can connect to a drive which has a program and transfer it, following the simple
steps described below.
1. Open the Program Editor. The auxiliary Drive Programming windows (Toolbox, Block
Parameters and Properties) will be displayed automatically.
2. Click the Transfer from Drive button in the program Editor Toolbar. The program will be
transferred from the drive and automatically displayed in the Program Editor designer area.
3. You may now edit the program, compile it, transfer it to the drive, export it, etc.
When a drive program is present, you can also transfer it from and to the drive with the Transfer to
Drive and Transfer from Drive buttons of the CX-Drive toolbar. In this case, a message dialog will ask
you whether to transfer the parameters, the program or both.

3-11 Creating a program with Text Editor
Follow the steps described below to create a drive program:
1. Open the program Editor. The Drive Programming auxiliary windows (Toolbox, Block
Parameters, Properties and Error List) will be displayed automatically.
2. The three ways to edit the code are:
a. Manual typing
b. Calling code snippets (Ctrl+Space)
c. Drag & Drop commands from Toolbox window (like Flowchart Editor)
3. You may now compile the program, transfer it to the drive, export it, etc.
Note 1: The Text editor is supported from CX-Drive version 2.50.
Note 2: Text and Flowchart Tasks/Subroutines can be used simultaneously within same program.
3-12 Run a program
After transferring the program to the device, you can run the program with the command or setting
the next inverter parameters:
·MX2 and RX:
Parameter
Value
Description
A017 – Drive
Programming Selection
0: Disabling Drive Programming program will be
stopped.
1: PRG terminal Drive Programming program will run by digital input. Set terminal to PRG
function.
2: Always Drive Programming program will be
always running.
·LX:
Parameter
Value
Description
F025 – Drive Programming
function selection
0: Disable Drive Programming program will be
disabled.
1: Enable Drive Programming program will be
Enabled.
F026 – Drive Programming
RUN trigger selection
0: TRM(‘PRG’ terminal) Drive Programming program will run by terminal. Set terminal to PRG
function.
1: PARAM
(setting F025=enable) Drive Programming program will run if F025 = enable
3-13 Comments – Text Editor
Only it is possible to add comments in a Text editor task or subroutine. To add a comment in a text line
press the character “’” follow by the comment. The comment will be showed in a green color format.
· Examples
Note: if you convert a Text task or subroutine to Flowchart, the comments will be lost.

3-14 #Alias definition – Text Editor
Only it is possible to define an alias in a Text editor task and before the command ‘entry’. It’s not
possible to define an alias in a subroutine.
Alias definitions are user-friendly names given to parameters, variables, commands and numerical
constants. There are two kinds of alias definition:
·Local alias: this alias definition only can be used in the current task and his subroutines, and
not in the other tasks and subroutines that the program could have. This is the format for a local alias
definition inside a task:
· Examples
·Global alias: this alias definition can be used in all the tasks and subroutines. This is the
format for a global alias definition:
· Examples
Note 1: The alias will be lost converting a text task/subroutine to flowchart. CX-Drive will show a
message advising about this issue.
Note 2: reserved words cannot be used like an alias. A compilation error will appear.
