Count Up/Count Down Format 
In the count up/count down format, one input takes each pulse as a positive step command, and 
another takes each pulse as a negative step command, as shown below. 
The drive can be set to increment position on the rising or falling edge of the signal. Stepping 
resolution can be programmed for electronic gearing. 
Quadrature Format 
In quadrature format, A/B quadrature commands from a master encoder (via two inputs) provide 
velocity and direction commands, as shown below. 
The ratio can be programmed for electronic gearing.
