Updating to RAM | Emerson FM-3 guide

Operational Overview

Keep option does not upload the NVM values into the user configuration (PowerTools Pro file).

The following table shows an example of how these options work:

		Before		After Download
		Download	Overwrite	Update Option	Keep Option
			Option		Keep Option
			Option
	PT Pro file value for	150	150	500	150
	Index.0.Vel	150	150	500	150
	Index.0.Vel

	NVM value for	500	150	500	500
	Index.0.Vel	500	150	500	500
	Index.0.Vel

Updating to RAM

The Update to RAM button can be used to send changes to the FM-3 module without performing a complete download. 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 FM-3. The changes will take effect immediately upon clicking on the button.

The parameters will be sent to the FM-3 module without stopping motion or disabling the drives. 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 below describes a typical process using the Update to RAM to make changes, and then downloading when complete to save changes to NVM.
