  Encoder Operation method

  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).

   

  Signal Circuit of encoder

  1. The NPN Open Collector -- The NPN Open Collector(NPN) is an interface based on an output circuit with an NPN transistor.

  An open collector is the unconnected collector connection of an NPN transistor, whose emitter is connected to earth and whose collector is connected to the output.

  2. PNP output

  The PNP output is an interface based on an output circuit with a PNP transistor.

  3. Push-Pull output(HTL)

  High Voltage Transistor Logic functions with a voltage supply in the range 10 and 30 V DC, with 24 V DC being the most usual.

  “Low” is defined as an output of between 0 V and 3 V and “high” as between VCC and VCC - 3.5 V.

  4. TTL RS-422 output

  In a transistor-transistor logic (TTL), both the logical status and the amplification are done by transistors, hence the name.

  The TTL output is supplied with either a fixed 5 V voltage or a variable voltage of between 10 and 32 V. For this the low range is defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.
