4-2 Function Mode Logic Operation Output This function outputs a logic operation result of the set two status. 4 Multi-function output item used for logic operation C141 RUN, FA1, FA2, OL, OD, AL, Dc, FBV, NDc Functions Input A C142 Logic operation AND, OR, XOR [LOG] RUN, FA1, FA2, OL, OD, AL, Dc, FBV, NDc Logic Output Function This function outputs the logic operation result of the two multi-function outputs. Allocate "10" (LOG logic output) to multi-function output terminal P1 or P2, or the relay output terminal. Network Signal Error Output (When the FieldBus Option is Used) •This function outputs a signal if an error is detected while the FiledBus option is used.
This works if the Inverter built-in network communication watchdog functions. You can the set timeout time in P044. The signal is output from the ODc allocated to the output terminal if communication has not been observed after the specified time period. 4-59 Data Symbol Function name Status Description 09 LOG Logic operation output ON See the figure below.
