15.3 Date and time
Overview
The converter continuously determines the date and time, e.g. to save the precise time that a
fault or alarm occurs.
Description of function
The converter has a hardware real-time clock. The hardware real-time clock continuously
determines date and time.
The following options are available to determine the date and time.
• Date and time are manually set
After the date and time have been set once at an operating unit, the converter calculates the
date and time based on its hardware real-time clock.
• The higher-level control is synchronized with the NTP server
The converter synchronizes the date and time with the higher-level control system via the
eldbus.
• Synchronize with another NTP server
The converter synchronizes the date and time with a central NTP server via the eldbus.
The hardware real-time clock buers power supply interruptions for up to 20 days.
