TTL mode

Connection of TTL encoders with or without zero pulse

TTL mode 1:Fig.32: Connection encoder TTL mode with zero pulse
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.33: Connection counter / pulse generator TTL mode with zero pulse
TTL mode 4:

Connection instructions

  • In TTL mode the inverse inputs are not connected.
  • When a counter/pulse generator is connected, the B track specifies 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.
