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.

Principle of encoder
The DNL accuracy is the phase angle error as an absolute value given in (mechanical) degrees.
An incremental encoder outputs a defined amount of pulses per revolution, so that every pulse is expected to be on a defined mechanical position. The maximum deviation between this ideal position and the actual position is called integral non linearity (INL). The INL accuracy is an important value if the incremental encoder is used for positioning tasks.
The duty cycle describes the ratio between “high” time to “low” time of an incremental encoder. Typically this ratio is 50/50, which is equivalent to 180 el° high and 180 el° low.
The performance of magnetic incremental encoders increases with higher PPR settings and higher rotation speeds (RPM). This is in contrast to optical encoders where the performance decreases. The DNL and INL accuracy that are stated in our datasheets are worst case values, a better performance can be expected for higher PPR and RPM.
This is the maximum frequency that the encoder is able to output via the output lines.
For example, the frequency of a 1024 PPR encoder that rotates at 600 RPM is 200 Hz (200*1024/60s).
