We have installed a speed sensor (PNP, 15000Hz) onto a MC42 frequency input (pin C1:28, PD).
The problem we have is that the raw value only goes up to about 2800Hz then zero's out with no further reading and we need to get a reading up to at least 5500Hz.
I have configured the input settings to: Max HZ -> 15000 and also the Scaled Maxed-> 15000 to mach the sensor's capabilities and then use the raw reading to scale a RPM value.
We tried adjusting the sensor closer to the ring gear, but no improvement.
So I did a test to see if it might be the sensor that is faulty by connecting the sensor to a different type/brand of controller. It immediately worked and gave the correct reading constantly.
The question is now... What am I doing wrong on the IQAN side?
