Fault display
(E.PUE)
Fault output
(ALM)
NOTES The fault output indicates fault output signal (ALM signal) or alarm bit output.
When the setting was made to provide a fault output, the fault description is stored into the
faults history. (The fault description is written to the faults history when a fault output is pro-
vided.) When no fault output is provided, the fault definition overwrites the fault indication of
the faults history temporarily, but is not stored. After the fault is removed, the fault indication
returns to the ordinary monitor, and the faults history returns to the preceding fault indication.
When the Pr. 502 setting is "1 or 2", the deceleration time is the ordinary deceleration time
setting (e.g. Pr. 8, Pr. 44, Pr. 45). In addition, acceleration time for restart is the normal
acceleration time (e.g. Pr. 7, Pr. 44).
When "2" is set in Pr. 502, run command/speed command at restarting follows the command
before an fault occurrence.
When "2" is set in Pr. 502 at occurrence of a communication error and the error is removed
during deceleration, the inverter accelerates again at that point.
