7.14 Data Loggers
7.14.1 Data Logs
The control includes three separate data loggers to record events detected by the software. The
logs are stored in non-volatile memory and you can capture data via the VFD’s USB ports or the
ethernet port.
• USB port: Use by inserting a USB disk drive. Logs are saved in the root directory of the
attached USB drive.
• Ethernet port: You must connect a PC, running the NXGpro ToolSuite software, to the drive
and upload the les directly from the PC. Refer to the NXGpro ToolSuite Software Manual for
operational information.
7.14.2 Event Log
The event log is a very large circular le that is used to record signicant drive events. Recorded
data is time stamped to a resolution of 1 millisecond. Data in the log includes:
• All alarms and faults, i.e. alarm/fault log data.
• All parameter changes.
• If enabled, the historic log at the time of a fault in a truncated form, to prevent event log
overow.
• Signicant events:
– CPU bootup including installed NXGpro software version.
– Medium voltage status.
– Drive operating state changes, e.g. idle, magnetize, run, stop.
– Precharge state changes
– Fault reset requests.
– Complete pre-charge sequence including success, all states and faults.
Refer to Event Log Menu (6180) in Section Options for Log Control Menu (6) of Chapter
Parameter Assignment / Addressing for associated parameters.
7.14.3 Alarm/Fault Log
The alarm/fault log consists of a circular buer that records up to 256 faults or alarms, so that you
can access the 256 most recent faults and/or alarms that have been detected. The faults and/or
alarms are time stamped to a resolution of 1 second, and also include a time stamp showing
when the fault and/or alarm was reset or cleared.
Refer to Alarm/Fault Log Menu (6210) in Section Options for Log Control Menu (6) of Chapter
Parameter Assignment / Addressing for associated parameters.
