Application Guide
Use this parameter to set a delay for temporarily forcing the fault response for a fieldbus communication fault from "No Action",
"Alarm", or "Alarm + Preset Fault Frequency" to fault. When a timeout occurs, the drive responds as selected with parameter ID 733
(7.179 (ID 733) Response to Fieldbus Communication
goes to a fault state and stops running.
If this parameter is set to 0.00 s, the fault response stays as it is set with parameter ID 733 and the drive runs indefinitely. If the fault
response is "Fault (Stop according to stop function)" or "Fault (Stop by coasting)", this delay has no effect.
7.189 (ID 752) Fieldbus Communication Fault Clear Delay
Location in the menu:
• INU application: P3.9.1.15
• AFE application: P3.8.1.17
Use this parameter to set a delay for accepting new fieldbus start commands, fieldbus reverse commands, and fieldbus refence
commands after a fieldbus communication fault has been cleared. The delay does not start after clearing a fieldbus communication
fault, but after the connection has been re-established.
7.190 (ID 759) Number of Trials
Location in the menu:
• INU application: P3.10.5
• AFE application: P3.9.5
• BCU application: P3.7.5
Use this parameter to set the total number of autoreset trials. If the number of trials during the trial time is more than the value of
this parameter, a permanent fault shows. If not, the fault goes out of view after the trial time is completed. The fault type does not
have an effect on the maximum number of trials.
