120V Power comes in the left top to a 25 Amp circuit breaker. From there individual leads go through fuses before powering the individual power supplies, except for the 36V psu and the VFD. Those leads go through a contactor first which gets tripped by a relay on the Acorn board once the Acorn boots up successfully. The VFD is front ended by an EMI filter.
This is a 2 axis machine running Leadshine drivers and NEMA23 closed loop motors.
Thanks to Gary Campbell and Jim Dawson for design ideas and Marty and Keith for troubleshooting help.
