4.4.1 Uploading

Uploading is the process of reading the configuration stored in the SM-EZMotion module and loading that data into a file on the PC. Arrow B on Figure 24 above represents a standard Upload. To upload a configuration from the SM-EZMotion module, first make sure the communications settings are correct, and then click on the Upload icon on the PowerTools toolbar or select Device > Upload from the Menu Bar.

PowerTools Pro configuration file (Arrow A on Figure 24 above). At the completion of the upload, the user will be asked if they wish to upload the NVM values. This dialog box is shown below.

Figure 25: Upload NVM Option Window

By selecting Yes, the values of all parameters stored in NVM will be uploaded and entered into the PowerTools Pro configuration file values (Arrow H on Figure 24 above). If No is selected, the values entered into the PowerTools Pro configuration file will remain the same as those that were last downloaded to the SM-EZMotion module.

4.4.3.2 Downloading

When downloading to the SM-EZMotion module the user will be required to select how to handle the NVM parameters upon downloading. Figure 26 below shows the dialog box asking the user to select one of three options for the download.

4.4.2 Downloading

Downloading is the process of sending the PowerTools Pro configuration from the PC to the SM-EZMotion module. Changes made in PowerTools Pro will not take effect until the information has been downloaded or the Update to RAM icon has been clicked. Arrow A on Figure 24 above represents a standard Download. To download information to a SM-EZMotion module, click on the Download icon on the PowerTools Tool Bar or select Device > Download from the Menu Bar.

The first time a download is performed, PowerTools Pro will lead the user through a series of dialog boxes to configure the baud rate and COM port of the PC to be used.

4.4.3Non-Volatile Memory (NVM) Options for Uploading and Downloading

When Uploading or Downloading, the user may be presented with options on how to handle the values stored in NVM memory. NVM is a type of memory that does not lose its contents when power is removed. Values in RAM are lost on power down, while values in NVM are retained. Following is a description of the options the user may encounter while uploading or downloading.

4.4.3.1 Uploading

When uploading from a SM-EZMotion module, the values that were last downloaded are uploaded and put into a

Figure 26: Download NVM Option Window

A description of each of the options is as follows:

Overwrite - This option will overwrite all the parameters stored in NVM with the current values in the user configuration (Just Arrow A in Figure 24). The values that are in NVM prior to the download will be lost.

Update - This option will upload the current NVM parameter values from the SM-EZMotion module and enter them into the user configuration. Once the NVM values have been stored in the file, the file is fully downloaded (First Arrow H followed by Arrow A in Figure 24. Data from H is saved in PowerTools Pro configuration).

Keep - This option will download the entire user configuration, but then NVM parameters will be restored to the value prior to download. This is similar to the Update option, but the Keep option does not upload the NVM
