General Information

Simulated Encoder Output

MN1230
The control provides a simulated encoder output at connector J3 as shown in Figure 3-5.
This output provides position information to the host controller. Use twisted pair wire with
an overall shield.
This output simulates a 1024 ppr encoder with quadrature outputs. Counting in
quadrature will provide 4096 ppr with one index marker (CHC) per revolution. It is
recommended that this output only drive one output circuit load. Driving multiple loads is
not recommended.
