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.
