TTL mode

Connection of TTL encoders with or without zero pulse

TTL mode 1:Fig.30: Connection of encoders in TTL mode with zero pulse in single-channel mode
TTL mode 2:

Connection instructions

  • In TTL 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 TTL counters / pulse generators with or without zero pulse

TTL mode 3:Fig.31: Connection of counters / pulse generators in TTL mode with zero pulse in single-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.
  • When using a counter / pulse generator without zero pulse C, the terminal points for the C track are not connected.
