When using signed binary data, the meaning of the signal will depend on the sign (+ or −).
If the sign is positive, the total number of bit pulses input is added:
0 0 1 0 1 0 0 1 0 0 1
: : : :
256+ 64 + 8 + 1 = 329
If the sign is negative, the negative of sum of the number of bit pulses input is used:
− (256 + 64 + 3 + 1) = −329
D
For incremental operations, binary references cannot be above 180_. For BCD references, references
above 180_ are possible depending on the setting of the BCD stop position reference resolution C2-12
(P
BCD
) to a maximum of ±360_.
The input signal circuit for the stop position reference for the Encoder orientation is the same as that shown
in 3.4.4 Sequence Input Signal Circuits.
