NOTE: Opto-Isolation of Outputs

A number of controller outputs are optically isolated to protect both the controller and the drive amplifier, such as HOME LIMIT and AMP FAULT.

The XMP's internal logic only controls current to the opto-transistor, thus presenting a "conducting" state between the collector and emitter (of the opto-transistor). Your external wiring determines whether an active low or an active high is presented at the input to your drive.

Note	To maintain electrical isolation between the XMP and external I/O, the power and ground connections should be from an external power source, and should not be tied to the XMP's power or ground connections.
