Data Interfaces

The Endpoint Controller’s integration interface is USB or CAN (Controller Area Network). “CANopen Implementation” on page 6-1 describes CAN communication specifications (data rates and protocol). Use the Endpoint Controller’s dual safety outputs to prevent any motion of the equipment under control (EUC) when the Endpoint Controller receives an emergency stop from either the connected remote device or its wired emergency stop input. The emergency stop inputs are relative to PVin. Maintain a single ground reference for all power and reference voltages.

The following table provides specifications for the CAN interface.
