Changing the drive parameters

Now that you have created a project drive, you can begin to manipulate the parameters. The

project drive should have identical parameters to the actual drive you will connect to later if you

entered the correct data when setting it up.

 Click the + next to the newly created project drive to expand the menu

 Click the + next to All Parameters to access the main menu parameters

 Click the + next to the main menu parameter group that you want to access

 Click the sub parameter group that the desired parameter resides in

 Double click the actual parameter of interest (under setup 1) and use the drop‐

down menus to make your selection

 Click the OK button to accept the change

Saving & opening a project file (.SSP)

When you have finished editing the drive parameters you will need to save the project file. Click

File from the tool bar at the top of the screen and then choose Save As from the drop‐down

menu. Name the file and click Save (it will be saved with a .SSP file extension). You can now close

the program. Locate the .SSP file that you saved and open it. The project will reopen, and the

project drive will appear with the same parameter settings that you had programmed previously.

Writing to a drive

You can connect to the drive and either read to or write from a project file. After the project drive

parameters have been set, follow the instructions listed below.

 Connect a USB cable between the drive and laptop (battery power only)

 Highlight the drive in the project that you want to work with

 Right click, select Write to Drive and wait until its finished

The connected drive will now have the same parameter settings as the project drive. You can also

use MCT 10 to program a drive directly through the USB cable, without creating a project drive. To

do this, connect your USB cable from the laptop to the VFD and wait until the software detects it.

You will see USB appear under the network column. Click the + and you will see the connected

drive which can now be programmed on the fly.
