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.

Register No. (Hex.)
15E0
Note:
• Refer to
H2: DIGITAL OUTPUTS on page 587
• 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 [NO,NC,CM 2nd Function, DO1 2nd Function, and DO2 2nd Function] to set the
function of the output signal for which you will perform logical operations.
Use H2-61, H2-64, and H2-67 [NO,NC,CM Logic Operation, DO1 Logic Operation, and DO2 Logic Operation]
to set the logical operation.

Note:
• If you use the function to output logical calculation results, you cannot set H2-01 to H2-03 = 1xx [Inverse Output of xx]. If you do, the
drive will detect oPE33 [Digital Output Selection Error].
• When you do not use H2-60, H2-63, and H2-66, set them to 0. The through mode function is not supported.
