TTL mode

Connection of TTL encoders without zero pulse in two-channel mode

TTL mode 1:Fig.36: Connection of encoders in TTL mode without zero pulse in two-channel mode
TTL mode 2:

Connection instructions

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

Connection of TTL counters / pulse generators without zero pulse in two-channel mode

TTL mode 3:Fig.37: Connection of counters / pulse generators in TTL mode without zero pulse in two-channel mode
TTL mode 4:

Connection instructions

  • In TTL 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 two-channel mode. The terminal points for the C track are assigned the signals of the second A track.
