Chapter 3
Functional Description

3-7

Due to the fact that bit numbering in the PLC Controller is done in Octal,
as opposed to decimal numbering in the drive Parameter 150, it is
necessary to relate the output image table bits to the controlled bits in
Parameter 150. Figure 3.4 shows the correlation between the output image
table bits and the drive Parameter 150 bits. As a result of this relationship,
if it is desired to set the start bit in Parameter 150 (bit 12 decimal), than bit
021/14 must be set as shown in the first rung of Figure 3.3. Control of
other logic bits is illustrated in Figure 3.3.
