5.4.11 History log
The history log is an area in the controller’s non-volatile memory that records “snapshots” of the system at
moments when important events occur. The history log is important especially for diagnostics of failures and
problems. When the history file is full, the oldest records are removed.
Each record has the same structure and contains:
• The event which caused the record (e.g. “Overspeed alarm” or “GCB closed”)
• The date and time when it was recorded
• All important data values like RPM, kW, voltages, etc. from the moment that the event occurred.
