04 FAULT HISTORY Fault history (read-only)
0401 LAST FAULT Code of the latest fault. See chapter Fault tracing on page
349 for the codes. 0 = Fault history is clear (on panel display
= NO RECORD).
1 = 1
0402 FAULT TIME 1 Day on which the latest fault occurred.
Format: Date if the real time clock is operating. / The
number of days elapsed after the power-on if the real time
clock is not used, or was not set.
1 = 1
days
0403 FAULT TIME 2 Time at which the latest fault occurred.
Format on the assistant control panel: Real time (hh:mm:ss)
if the real time clock is operating. / Time elapsed after the
power-on (hh:mm:ss minus the whole days stated by signal
0402 FAULT TIME 1) if real time clock is not used, or was
not set.
Format on the basic control panel: Time elapsed after
power-on in 2 second ticks (minus the whole days stated by
signal 0402 FAULT TIME 1). 30 ticks = 60 seconds. For
example, value 514 equals 17 minutes and 8 seconds (=
514/30).
1 = 2 s
0404 SPEED AT FLT Motor speed in rpm at the time the latest fault occurred 1 = 1 rpm
0405 FREQ AT FLT Frequency in Hz at the time the latest fault occurred 1 = 0.1 Hz
