The table below shows an example of how these three options work:
5.4.4 Update to RAM
The Update to RAM button can be used to send changes to EZMotion without performing a complete download (symbolized
by Arrow F in Figure 25). The Update to RAM button is found in the PowerTools Pro toolbar. This operation will send only
those changes that have been made since the last Update to RAM or Device > Download to EZMotion. The changes will take
effect immediately upon clicking on the button.
The changed parameters will be sent to EZMotion without stopping motion or disabling the drive. Because of this, it is
important to use caution when changing motion parameters while the motor is in motion.
The Update to RAM button saves the parameters only to RAM and not to Non-Volatile Memory (NVM). Therefore, if the
system power is removed, any changes made using the Update to RAM button will be lost. In order to save changes to NVM,
a full-download must be performed.
The flowchart in Figure 29 describes a typical process using the Update to RAM to make changes, and then downloading
when complete to save changes to NVM.
Figure 30: Update to RAM flowchart
The Update to RAM button operates according to the following rules:
• If no parameters have been modified, the Update to RAM button will be disabled.
• If the user modifies a parameter that does not require a full download, the Update to RAM button will become enabled.
• If while the button is enabled, the user modifies a parameter that requires a full download, the Update to RAM button will
become disabled.
• When the user clicks on the Update to RAM button, all the modified parameters are transmitted to EZMotion. Once
transmitted, the button will become disabled again until another parameter is changed.
• If the user performs a full download while the button is enabled, the Update to RAM button will be disabled when the
download is complete.
• If the user modifies parameters, and then disconnects (stops communications), the Update to RAM will be disabled, and
the changes will not be sent.
5.4.5 PowerTools Pro Operation Preferences
To avoid getting all the option windows described above every time an Upload or Download is performed, the user can set
certain preferences. To configure the preferences, select Options > Preferences > Ptools Operation from the menu bar.
Figure 30 shows the Preferences window.
