Features of the TTL module

To obtain adequate position and speed accuracy, the combined method is used. The method is a combination of edge counting and time measurement. At very low rotation speeds especially, precise determination of the position and speed values is essential.

Operation modes of the TTL module

• Evaluation of a TTL encoder
• Simulation of a TTL encoder (signals from other encoders are converted into TTL signals and made available as output signals for a slave axis)
• The maximum pulses per revolution is limited to 20 bits (P 2621).
• TTL repeater (evaluation and transmission of incoming TTL signals for additional axes)
• Simultaneous evaluation and simulation of a TTL encoder
