Open Collector mode

Connection of open collector encoders with or without zero pulse

Open Collector mode 1:

Open Collector mode 2:

Connection instructions

  • In open collector mode the inverse inputs are not connected.
  • When using an encoder without zero pulse C, the terminal points for the C track are not connected.

Connection of open collector counters/pulse generators with or without zero pulse

Open Collector mode 4:

Connection instructions

  • In open collector mode the inverse inputs are not connected.
  • If a counter/pulse generator is connected, the B track determines the counting direction.
    Input B̅ is not connected.
  • When using a counter/pulse generator without zero pulse C, the terminal points for the C track are not connected.
