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 values into the user
configuration (First Arrow H followed by Arrow A, but data
from H is not stored in PowerTools Pro file).
The table below shows an example of how these three
options work:
4.4.4 Updating to RAM
The Update to RAM button can be used to send changes
to the SM-EZMotion module without performing a complete
download (symbolized by Arrow F in Figure 24). 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 the SM-EZMotion module. The changes will
take effect immediately upon clicking on the button.
The changed parameters will be sent to the SM-EZMotion
module 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 27 describes a typical process
using the Update to RAM to make changes, and then
downloading when complete to save changes to NVM.
Figure 27: 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 the
SM-EZMotion module. 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
button will be disabled, and the changes will not be
sent.
4.4.5 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 28 shows the Preferences Configuration
window.
