INVERTER SETTING
CAUTION
1. A communication line fault [E.OP3 (alarm data: HA3)] is a fault
that occurs on the communication line, and a fault of the option
unit itself [E. 3 (alarm data: HF3)] is a communication circuit fault
in the option.
2. The alarm output is the ABC contact output or alarm bit output.
3. 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).
4. The acceleration time at a restart is the ordinary acceleration
time setting (e.g. Pr. 7, Pr. 44).
5. When the Pr. 502 setting is "2", the operation/speed command at
a restart is the one given before the fault occurrence.
6. When the setting was made to provide an alarm output, the fault
definition is stored into the alarm history.
(The fault definition is written to the alarm history when an alarm
output is provided.)
When no alarm output is provided, the fault definition overwrites
the alarm indication of the alarm history temporarily, but is not
stored.
After the fault is removed, the alarm indication is reset and
returns to the ordinary monitor, and the alarm history returns to
the preceding alarm indication.
7. When a communication line fault occurs at the Pr. 502 setting of
"2", removing the fault during deceleration causes acceleration
to restart at that point.
(Acceleration is not restarted if the fault is that of the option unit
itself.)
