5.2.2. Error history buffer
For purposes of diagnostics, the error history buffer contains the last 32 error and warning
messages of the inverter, which have occurred during operation. The error history buffer
can be read out using the keypad via P155.00 and provides a limited view on the logbook.
Details
• For each event that is recorded, the error history buffer contains the message text, the
error code, the time of occurrence as well as a counter for successive, identical events.
If an event that has already been recorded occurs repeatedly, only the counter is
incremented.
• The error history buffer can be reset by the user. In order to prevent the buffer from
being reset by the user, this function can be protected by means of a password.
• Observe that the error history buffer only presents a snapshot at the time the data are
read out. If a new event occurs, the error history buffer must be read out again via
P155.00 so that the new event becomes visible.
