InterfaceIncremental signals « TTL
AMO-measuring systems with « TTL Interface contain electronic, which form the sine-form signals - with or without -Interpolation into digital signals.
The incremental signals are outputed as rectangle pulses A+ and B+ with 90° el. phase shifting.The rectangle-mark-signal is composed from one or more reference impulses R+, which are assigned with the incremental signals:The integrated electronic additionally creates the inverse signals A-, B- and R- for a safe transmission.The showed sequence of the outputed signals - B after A - is valid for the in the connection drawing stated movement direction.
The measuring step results through the distance between two flanks from the incremental signals A+ and B+ through 1-fold-, 2-fold or 4-fold evaluation.
