occurs.

Note: 1. A communication line fault [E.OP3 (alarm data: HA3)] is a fault that occurs on the
communication line, and a fault of the CC-Link plug-in option itself [E. 3 (alarm data:
HF3)] is a communication circuit fault in the communication 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
setting (e.g. Pr. 8, Pr. 44, Pr. 45).
4. The acceleration time at a restart is the ordinary acceleration 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 CC-Link plug-in option itself.)
