Note: 1. A communication error [E.OPT (fault data: A0
H
)] is a fault on the communication
line, and a communication error [E.3 (fault data: F3
H
)] is a communication error
inside the inverter.
2. The alarm output is the ABC contact output or alarm bit output.
3. If the Pr. 502 setting is 1 or 2, the deceleration time is the ordinary
deceleration time setting (Pr. 8, Pr. 44, Pr. 45).
4. The acceleration time at restart is the ordinary acceleration time setting (Pr. 7,
Pr. 44).
5. If the Pr. 502 setting is 2, the operation command/speed command at restart
follows the command before occurrence of a fault.
6. For the setting of alarm output, the fault definition is stored in the alarm history.
(Write to the alarm history is performed when the alarm output is provided.)
If the alarm output is not provided, the fault definition overwrites the alarm
indication of the alarm history temporarily but is not stored.
After the fault is cleared, the alarm indication is reset and returns to the
ordinary monitor and the alarm history returns to the original alarm history.
7. When a communication line fault, which occurred at the Pr. 502 setting of 2, is
cleared during deceleration, acceleration restarts at that point. (Acceleration
does not restart at occurrence of a CC-Link microcomputer fault.)
