What does the message "Memory battery weak" indicate on the pendant?

The message "Memory battery weak" specifically indicates that the battery responsible for maintaining the controller's memory is losing its charge and may soon fail. In many control systems, including those used with robotics, a memory battery is crucial for preserving settings, configurations, and accumulated data, even when the main power supply is disconnected. When this battery weakens, the system alerts the user to prevent potential data loss or operational issues.

In this context, the memory battery's health is directly tied to the functioning of the controller, making it vital to address this issue promptly to avoid operational interruptions. On the other hand, recalibrating the pendant, being in idle mode, or needing a software update pertain to operational or functional aspects rather than the status of the memory battery. These alternatives do not address the specific nature of the warning regarding the battery's condition.
