Digital Dream DDCS V2.1 - Wiring; Power supply explanation; Product Wiring

2 Wiring
In general, the power supply of industrial control’s equipment products are complex. They have many
different ground levels. The internal power structure of this product is as follows:
See picture 2-1. The Master Power input and MPG module and stepper control module have the same
ground. Limit,ESTOP and other input modules as well as the spindle speed control output /M3/M8/M10 and
other output modules have the same ground, which use optical isolation. The Limits, E-STOP and other input
modules are connected with the same positive. The controller provides 12V as the common + port, without the
requirement of the external power source. As for the spindle port, take the output ground for references and the
0-10V adjustable voltages to adjust the spindle speed (refer to spindle VFD manual). The M3/M8/M10 digital
output ports pull to ground. You can connect an external relay with up to 50mA direct to 12V+ and the M
connector (Solid State relays usually pull between 15 and 20mA)
As the picture shows, the wiring section of the controller has Input Ports,Spindle&Output Ports,tepper/Ser-
vo control step and direction output,MPG Port, USB Port and Power supply Port.
