This power and safety control hub for overall power control, safety control and power distribution integrates fault tolerant power disconnect control, software monitoring of disconnect and multi-voltage power distribution and disconnect with non- hazardous power control, EMI filtering and multi-circuit current protection in a single unit. In addition, it implements electromagnetic, single fault tolerant, safety control circuits without using positively driven contact relays. It coordinates the shutdown of any connected mechanical drives such as servo motor drives, stepper motor drives and variable speed drives autonomously commanding them to come to a controlled stop before safety power is disconnected (when networked controls are used). It also integrates segmented hazardous power control (load/unload and main machine/equipment areas) so that the main area can be operating while the load/unload area has power disconnected. Further, it automatically discharges energy sources within connected mechanical drives at the time of safety power disconnect of hazardous power. It also utilizes a safety control and monitoring algorithm that automatically forces the test on e-stop switches and interlocks in a machine each time the machine is powered up or reset. In addition, it has a state driven safety control and monitoring algorithm that pinpoints wiring and device problems for rapid debug. It includes internal self protection that automatically forces a control safety power disconnect (after warning the host) if the unit should approach its maximum operating temperature, or if a cooling fan stops. Further, it incorporates safety monitoring software for the synchronous de-bouncing of the interlock and e-stop switch inputs (as a vector) to eliminate false trips. It also integrates a comprehensive audible overcurrent trip indicator as well as individual visual overcurrent indicators in the power distribution system and an e-stop reset function into the machine on-off front panel switch. Finally, our power and safety control hub for overall power control, safety control and power distribution includes a "soft-off' circuit that automatically shuts off the machine when the power supply voltage to a host computer is shut down.
