 Advanced Pulse counter functionality has limitations when pulse is at different duty cycle and signal voltage at 2kHz frequency. Exceeding limitations might lead to unexpected pulse count or even stop functionality from working. Tables below shows those limitations for specific DIN.
 Devices on DIN2 support up to 2kHz pulse frequency. Pulses can be with different duty cycles, but only pulses that are greater that 120us is counted, otherwise they are filtered as signal noise. In other words, pulse change between low and high state should not take longer than 120us. Also, there is a pulse rise time that affects time when voltage threshold is reached. So, for 2kHz there is limitations for available duty cycle.
