REMARKS
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 provided.)
When no fault output is provided, the fault record 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.
