Fig. 6-123: Operations when an Ethernet board fault occurs
NOTES Ethernet communication fault "E.OP1 (fault data: HA1)" appears at error occurrences on the Ether-
net communication line. Ethernet board fault "E.1 (fault data: HF1)" appears at error occurrences in
the communication circuit inside the Ethernet board.
Fault output indicates the fault output signal (ALM signal) and fault bit output.
When the fault output setting is active, fault records are stored in the faults history. (A fault record is
written to the faults history at fault output.) When the fault output setting is not active, fault record
is overwritten to the faults history temporarily but not stored. After the error is removed, the fault
indication is reset, changing the display back to normal, and the last fault is displayed in the faults
history.
The LF signal turns OFF when the fault is removed.
When the Pr. 502 setting is "1" or "2", the deceleration time is the normal deceleration time setting
(e.g. Pr. 8, Pr. 44, Pr. 45).
The acceleration time at a restart is the normal acceleration time setting (e.g. Pr. 7, Pr. 44).
When the Pr. 502 setting is "2", the operation/speed command at a restart is the one given before
the error occurrence.
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 does not restart at an Ether-
net communication line error of the inverter.)
CAUTION
E
When a communication line error occurs while Pr. 502 = "3", the inverter continues operation.
When setting "3" in Pr. 502, provide a safety stop countermeasure other than via communica-
tion. For example, input a signal (RES, MRS) through an external terminal or press the PU stop
on the operation panel.
