Principle of encoder
he differential outputs have the highest frequency response
capability and the best noise immunity. To ensure this the receiver
should also be a differential.
Replacement of Older Output Drivers
A logic gate interprets certain input voltages as high (logic 1) or
low (logic 0).
TTL (transistor-transistor-logic): A signal above 2 V is
interpreted as logic 1 and a signal less than 0.8 V is interpreted
as logic 0. The output voltage ranges between 0-5 V.
HTL (high-threshold-logic): A signal above 3 V is a logic 1 and a
signal less than 1 V is a logic 0. The high output signal level is
dependent from the supply voltage. Because of the higher voltage
difference between logic 0 and 1, the HTL logic is more immune to
interference and more resistant against electrical noise.
Mechanical degree is the actual rotation of the shaft in degrees.
Electrical degree is used for electrical signals. The required time
for completing one alternating voltage/current cycle is defined as
360 electrical degrees (el°). For incremental encoders, one cycle
is equal to one complete pulse. With a given PPR the electrical
degree can be converted to mechanical degree for any incremental
encoder.
About Encoder Vibration
Vibration acting on an encoder always cause wrong pulse easily.
So we have to pay more attention to encoder working place.
The more pulse per round, the narrower groovy spacing of grating,
ore effect to encoder by vibration, when motor speed is low or even
stopped, vibration acting on encoder shaft or encoder shell would
cause grating vibration, in this way, encoder might show wrong
pulse signal.
