Measuring Unit Output Signals; Output Signal Phase Difference - Sony DK110NLR5 Bedienungsanleitung

5. Measuring unit output signals

The signals output from this measuring unit are phase A/B/Z signals in the form of voltage-
differential line driver output compliant with EIA-422.
Phase A
Phase B
Phase Z
The reference point is the synchronized reference point that is at Hi level when the phase A
and phase B are at the Hi level.
Output signals at maximum response speed (at approx. 250 m/min)
Before using, check that the minimum input phase difference of the control device connected
to this measuring unit or the counter is smaller than 50 ns (phase A cycle: 200 ns, 5 MHz).
* The minimum phase difference can be modified under special specifications.
(See "5-1. Output signal phase difference")

5-1. Output Signal Phase Difference

The travel amount of the measuring unit is detected every 50 ns, and the phase difference
proportional to the amount traveled is output. The phase difference changes in integer multiples
of 50 ns.
Also, the minimum phase difference for the phase A and phase B is 50 ns.
