Analogue output signals - RGH41A, B
Limit
open collector output, asynchronous pulse
Output specifications
Digital output signals - RGH41T, D, G, X, N, W, Y, H
Form - square wave differential line driver to EIA RS422A (except limit switch P, Q, Alarm E- and external set-up signal X)
Incremental
†
2 channels A and B in quadrature (90° phase shifted)
Alarm
†
single limit readheads - differential line driven output
dual limit readheads - single ended line driven output
For RGH41T, G, X alarm asserted
for signal amplitude <15 %.
Either asynchronous pulse E
as shown (options 03/05) or
line driver channels 3-state
(options 04-06).
For RGH41N, W, Y, H - alarm
asserted when:
- Signal amplitude >150%
- Readhead exceeds specified
maximum speed
Also, outputs are 3-stated at
signal amplitude <15%

Set-up
Between 50% and 70%
signal level , X is a duty
cycle, 40 µm duration.
Time spent at 5 V increases
with signal level.
At >70% signal level X is
nominal 5 V.
