Sony LZ51-B Bedienungsanleitung Seite 113

Note that because there is an input circuit delay, operation is the same as before the DRQ signal input until the DRQ signal is
relayed internally.
Note that the READY signal may be output during that interval.
BCD
data sign
READY
(negative logic)
DRQ
(EX.IN)
In addition, when EX.IN is used instead of DRQ, the delay from when EX.IN is input until BCD stops is longer than ∆T.
For 1st axis input and the LZ51-B expansion unit
∆T → ∆T + 35 ms Therefore, the delay after DRQ input until data output is about 3 ms + ∆T + 35 ms.
For 2nd axis input and the LZ51-B and LZ51-K/LZ51-R expansion units
∆T → ∆T + 38 ms Therefore, the delay after DRQ input until data output is about 3 ms + ∆T + 38 ms.
