Logic Linking Of A And B - Eaton M-Max Series User Manual

Parameters
Logic Function (P13)
The logic function enables you to link both parameters P13.1 (A) and P13.2 (B) logically with
each other. The result (LOG) can then be assigned to the digital outputs DO (P5.3), RO1 (P5.1)
and RO2 (P5.2). The type of operation (And, Or, Exclusive-Or) is defined in parameter P13.3.

Example: Digital output RO1 (N/O contact R13/R14) is required to indicate during operation
that the set current limit has been reached:
P5.1 = 24, LOG function fulfilled
P13.1 = 2, Operation (RUN), signal A
P13.2 =27, Current monitoring, signal B
P13.3 = 0, A AND B
