Stop operation selection at occurrence of communication fault (Pr. 502)
Stop operation when retry count exceeds (Mitsubishi
inverter protocol only) or signal loss detection error
occurs can be selected.
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 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 ([ Pr. 8,
Pr. 44, Pr. 45 ]). In addition, acceleration time for restart
is the normal acceleration time ([ Pr. 7, Pr. 44 ]).
When "2" is set in [ Pr. 502 ], run command/speed
command at restart 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.
