Connection instructions

  • In open collector mode the inverse inputs are not connected.
  • Only encoders without zero pulse are suitable for use in 2-channel mode. The terminal points for the C track are assigned the signals of the second A track.

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.
  • Only counters/pulse generators without zero pulse are suitable for use in 2-channel mode. The terminal points for the C track are assigned the signals of the second A track.
