KJ50 angel sensor absolute encoder external diameter 50mm 720ppr 10
bit CW direction hole 14mm absolute digital 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.
