PARAMETERS

Operation setting at fault occurrence
5.14.4 Display and erasure of communication error occurrence count (Pr. 501)
(1) Display and erasure of communication error occurrence count
The cumulative number of communication error occurrences can be indicated.
Writing "0" to Pr.501 erases this cumulative count.
At the point of communication line error occurrence, Pr.501 display is incremented by 1.
(2) Inverter operation at communication error occurrence
The inverter operates as below at a communication line error or a fault in the FL remote communication circuit.
Operation at error occurrence
Operation at error removal
The inverter operates as below at a communication error during FL remote communication.

The cumulative number of communication error occurrences
can be indicated.
Writing "0" erases this cumulative count.
∗ The above parameter can be always read regardless of the Pr.160 User group read selection setting. (Refer to page 167)
NOTE
y The communication error count occurrence is stored into RAM temporarily. Since this data is stored in EEPROM at
one-hour intervals, performing power-ON reset or inverter may cause the Pr. 501 data to be the value stored in
EEPROM the last time depending on the reset timing.
Error Definition Operation Indication Fault Output
Communication line Decelerated to stop E.OP1 lit after stop Provided after stop
FL remote communication
circuit in the inverter
Decelerated to stop E.1 lit after stop Provided after stop
Error Definition Operation Indication Fault Output
Communication line Kept stopped E.OP1 kept lit Kept provided
FL remote communication
circuit in the inverter
Kept stopped E.1 kept lit Kept provided
NOTE
y Communication line error [E.OP1] is displayed when a fault occurs on the FL remote communication line.
y The fault output indicates fault output signal (ALM signal) or alarm bit output.
y The fault record is stored into the faults history. (The fault record is written to the faults history when a fault output is
provided.)
After the error is removed, the fault indication is reset and returns to the ordinary monitor, and the faults history
returns to the preceding fault indication.
y The deceleration time is the ordinary deceleration time setting (e.g. Pr. 8, Pr. 44, Pr. 45).
