For the PD-xxP models, there are two methods of generating encoder output signals.
For the Open Collector method, the output frequency is limited to 200,000 pps (which is 800,000 counts/sec post-quadrature)
For the Line Drive method, the output frequency is limited to 2,000,000 pps (which is 8,000,000 count / sec post-quadrature)
