Note
As a general guideline it can be stated that if you want the timing requirements for
the Counter Inputs to satisfy the above mentioned specifications, you must pay
attention to the type of output driver of the encoder being used, the length of the
encoder cable and the frequency of the count pulses generated. For example, if
