5) Measure voltage at resistance without wheel
rotation.If voltage is out of specification, check
sensor, mating encoder and their installation
conditions.
Voltage at the resistance (115
Ω) without wheel
rotation
680 – 960 mV
6) Measure voltage at resistance with wheel rotation
and confirm voltage alternately changes between
high and low voltages.If voltage does not change
with wheel rotation, check sensor, mating encoder
and their installation conditions.
Voltage at the resistance (115
Ω) with wheel
rotation
