INVERTER SETTING
Operation at error removal
Alarm Definition
Communication line
Communication
option itself
CAUTION
1. A communication line error [E.OP1 (alarm data: HA1), E.OP3 (alarm data: HA3)] is an error that occurs on
the communication line, and an error of the communication option unit itself [E. 1 (alarm data: HF1), E. 3
(alarm data: HF3)] is a communication circuit error in the option.
2. The alarm output indicates alarm output signal (terminal ABC1) or alarm bit output.
3. When the setting was made to provide an alarm output, the error definition is stored into the alarm history.
(The error definition is written to the alarm history when an alarm output is provided.)
When no alarm output is provided, the error definition overwrites the alarm indication of the alarm history
temporarily, but is not stored.
After the error is removed, the alarm indication is reset and returns to the ordinary monitor, and the alarm
history returns to the preceding alarm indication.
4. 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).
5. The acceleration time at a restart is the ordinary acceleration time setting (e.g. Pr. 7, Pr. 44).
6. When the Pr. 502 setting is "2", the operation/speed command at a restart is the one given before the error
occurrence.
7. When a communication line error occurs at the Pr. 502 setting of "2", removing the error during deceleration
causes acceleration to restart at that point. (Acceleration is not restarted if the error is that of the option unit itself.)
