2.1 Device Power supply Solution
The power supply solution in the field of the Industrial automation is always very
complicated, there is a lot of the GND, now we descript the structure of the power supply as
below:
The power supply structure as the Figure 2-1,main power supply input and MPG module and
stepper control output module are common GND, Limited and Estop input module and Spindle
speed adjust module are common GND, between main power supply and output module there are
photoelectric isolation. The inputs of limited switch and Estop and so on are Common cathode,
inside of the device, there is GND as common-, no need to connect external power supply. Based
on the reference of output GND interface, output a 0-10V adjustable voltage to adjust the spindle
speed. The chassis is built with 220V to 48V DC supply to the DC brushless spindle and 4 step
motor driver.
