6.9.4 Technical characteristics of the Lenord+Bauer sine
encoder
Trend of signal A over time:
CHARACTERISTICS VALUE
Rated power supply "U" 5V DC +/- 5%
Operating temperature -30° C ÷ 85° C (-22° F ÷ 185° F)
Max. operating altitude 2000m (6500ft)
Signal input
128 pulses per rotation + zero notch
100 pulses per rotation + zero notch
A/B signal output 500 mV peak-to-peak with average value “U ref.”=U/2
1V peak-to-peak as difference of signals with
average value “U ref.” (see figures below)
A/B signal phase displacement 90° (a quarter period)
Z signal output 500 mV peak compared with idle value
U ref. ±80mV
1V peak as difference of signals with idle value U ref.-
160mV= 2.34V (see figures below)
A voltage level higher than the one specified (5V ±5%) may damage the encoder
reader.
