3 OPERATIONAL NOTES
The S200 Position Node product is simple and intuitive to setup and use.
Chapter 5 is designed to help the user step through the User Interface
Software, S200 OC TOOLS, explaining much of the operation and setup.
Chapter 4 is designed to provide some insight on the application setup for the
product and to discuss some details about the product operation.
3.1 ENCODER INPUT CHANNELS
The S200 CNS Option has the ability to accept pulsed position command input.
The digital command can be set to come from an incremental encoder
(gearing), step and direction controller (pulse and direction), or count up/down.
The inputs for these modes come in the encoder input connections on J12 pins
12-15.
The internal circuitry of these 4 inputs is shown in the following diagram. The
circuits are designed to facilitate a wide range of compatible driver
configurations. They may be tied to differential line drives (as with normal
incremental encoders), Open Collector Outputs (some pulse and direction
controllers), or TTL drivers (wide applications). Driving circuits should be wired
accordingly and must have the DC Commons of the drive and controller tied
together. Failure to tie the DC commons together can cause operation that is
difficult to predict.
