Network Detection Signal (FieldBus Option)
The Network Detection Signal output indicates the general status of network
communications when using a FieldBus option. The inverter has a programmable
watchdog timer to monitor network activity. Parameter P044 sets the time-out period. If
communications stop or pause longer than the specified time-out period, the ODc output
turns ON.
