Resolver
Error acceptance
Short circuit between any two
conductors of the connecting
cable
Interruption of any conductor of
the connecting cable
Static "0" or "1" signal at the in­
puts and outputs, individually or
simultaneously at multiple in­
puts/outputs
Interruption of high-impedance
status on a single input/output
or multiple inputs/outputs sim­
ultaneously
Reduction or increase of the out­
put amplitude
Interference vibration on one or
more outputs
Change of phase shift between
output signals
Fastening becomes loose when
idling:
– Sensor housing separates
from motor housing
– Sensor shaft separates from
motor shaft
Mounting comes loose during
movement:
– Sensor housing separates
from motor housing
– Sensor shaft separates from
motor shaft
Measuring element is coming
loose (e.g. optical encoding disc)
No light from transmitter diode

Use fault exclusion for
the motor - encoder
system, or a second
measuring system for
position comparison.
