Extend MFDO1 to MFDO3 Function Selection
You can set MFDO functions to bit 0 to bit 2 [Mbus MFDO1 to 3] of Modbus register 15E0 (Hex.). Use H2-40 to
H2-42 [Mbus 15E0h b0 Output Function to Mbus 15E0h b2 Output Function] to select the function.

Note:
• Refer to H2-xx "MFDO Setting Values" for more information about MFDO setting values.
• When you do not set functions to H2-40 to H2-42, set them to 0.
■
Output of Logical Operation Results of MFDO
This enables the logical operation results of two MFDOs to be output to one MFDO terminal.
Use H2-60, H2-63, and H2-66 [2NO-2CM 2nd Function, 3NO-3CM 2nd Function, 4NO-4CM 2nd Function] to
set the function of the output signal for which logical operations are performed.
Use H2-61, H2-64, H2-67 [2NO-2CM Logic Operation, 3NO-3CM Logic Operation, 4NO-4CM Logic Operation]
to set the logical operation.

Inverse output of 0 to A7
Sets an inverse output of the function for
the MFDO. Put a 1 at the front of the
function setting to set inverse output. For
example, set 138 for inverse output of 38
[TrqDetect2NC].
