3.4 Operation at Communication Error Occurrence
3.4.1 Operation selection at communication error
occurrence (For the FR-A500/V500 series only)
You can select operations at error occurrences by setting Pr. 500 to Pr.
502 under network operation.
• Parameter setting
1) Pr. 500 "communication error recognition waiting time"
You can set the waiting time from when a communication line fault
occurs until it is recognized as a communication error.
If the communication line fault still persists after the time set in Pr. 500
has elapsed, it is recognized as a communication error.
When the fault is restored to normal communication within the set time,
it is not regarded as a communication error and operation continues.
REMARKS
For the FR-A500, Pr. 500 to Pr. 502 are available with an upgraded inverter.
Refer to the inverter manual for the availability of the parameters.
