ENC-ADAPTER

Multifunction interface for encoders

The ENC-ADAPTER interface solves many interfacing problems between encoders equipped with different kinds of outputs and systems which require push-pull encoders, PNP or NPN.

Other than the interfacing function, ENC-ADAPTER is equipped with the divisor function as well. This function reduces the frequence generated by the encoder when it’s higher than the frequence managable by the connected board.

In the image below, the block diagram of the ENC-ADAPTER interface.

You can see the following blocks:

  • Adapter / duplicator: it’s the part assigned to encoders with line-driver outputs. Other than connecting the encoder with the interface, it also works as a duplicatorfor the pulses generated by the encoder. This function doubles the resolution of the connected encoder.
  • Adapter: it’s the part dedicated to the encoders equipped with PNP, NPN or push-pull outputs. In contrast to the block 1, on this input no duplication is done.
  • Pulse generator: It’s the part that generates a stable and fixed frequency. it can be used together with the diving block to obtain preset frequencies, which are useful, for example, to simulate an encoder in lines that don’t have one.
  • Select functioning mode: allows you to select which one of the 3 signal sources must be used to pilot the output. The available options are: line-driver encoder, PNP/NPN encoder and pulse generator.
  • Divisor 1:2 – 1:4096: It divides the frequency set by the block 4, then direct it to the output. Through a enable/disable input (divisor interruption signal), it’s possible to stop the divisor (in this way there won’t be pulses on the output).
  • included/excluded divisor selector: allows you to set if the pulses generated by the encoder (or the internal generator) have to go through the divisor or if they have to reach the output without any other variations.
