![]() ![]() This method should prevent a single failure from destroying everything. If you want everything grounded together (and you should), run a separate ground wire from each piece of equipment to a common grounding point near your master power input. Each serves an isolated purpose, and their isolation is an attempt to protect your equipment. Note: DCM, ACM, and GND (all grounds) are not connected together. Choosing the right method may require some experimentation. Note: For the motor drivers, you will use either the 5V or the GND connection, not both. This should come from the VFD low voltage supply (10V to 13V) output.Ħ) 5V: is a low power output to supply the motor driver opto-isolators providing you use "Low-True" logic (pull to ground for ON)ħ) GND: output is the ground to the motor drivers used when driving "High-True" logic (Pull to 3,3V to 5V for ON). It goes to the AVI pin on the VFD.ĥ) 10V: is the input analog reference voltage for the spindle speed control. It goes to the ACM pin on the VFD.Ĥ) AVI: is the analog output to the spindle speed control. It is usually the same voltage that supplies the motor drivers, but it can be a separate supply (200ma minimum).Ģ) DCM: connection is digital ground for both input switches (Limits, E-Stop, & Probe) and output loads (VFD Start, Flood, & Mist).ģ) ACM is the analog ground specifically for the spindle speed control. ![]() To add a little more to the BSMCEO4U-PP definitions.ġ) 24V: Input can be anywhere from 12V to 36V to power the digital input and outputs only. ![]()
