State Description
ON or The encoder has signal input.
flash
OFF The encoder does not have signal input.
Normal.
OFF Power is not connected.
ON
Input signal is slightly instable, which occurs
when motor accelerates/decelerates or
encoder signal input suffers slight interference.
OFF Input signal is normal, speed is stable and
there is no interference.
Flash Input signal is moderately instable, which
slowly occurs when motor accelerates/decelerates
or encoder signal input suffers moderate
interference.
Flash Input signal is seriously instable, which
quickly occurs when motor accelerates/decelerates
quickly or encoder signal input suffers severe
interference.
ON Signal is slightly instable, which occurs when
motor accelerates/decelerates or interference
during signal input is not completely filtered
(The number of interference pulses that are not
filtered is less than 10 per time unit).
OFF
Signal processing is normal, speed is stable
and there is no interference.
Flash Signal is moderately instable, which occurs
slowly when motor accelerates/decelerates or
interference during signal input is not
completely filtered (The number of interference
pulses that are not filtered is less than 30 per
time unit).
Flash Signal is seriously instable, which occurs when
quickly motor accelerates/decelerates or interference
during signal input is not completely filtered
(The number of interference pulses that are not
filtered is more than 30 per time unit).
ON Inter-lock enabled.
OFF Inter-lock disabled.
ON Normal.
OFF The system is not operating or abnormal.
Flash The encoder cable breaks.
