7.1.2.1 Output of the encoder position of the DI1/DI2 frequency input
The LS_DigitalInput system block includes an integrator for providing the encoder position.
• The integrator can take max. ±32000 encoder revolutions.
• The starting position can be loaded via inputs.
• The internal function can be set via parameters.
• In addition to the encoder position, the "Overflow occurred/distance processed" status signal is
provided.
