 2. Product Wiring Overview

The circuit switching wiring board provides screw terminals for power (24VDC), input signals, spindle control, pulse and direction for X/Y/Z/A/B stepper/ servo drives, MPG, input and output ports as well as an USB input.

Please see the reference following in detail.

There are two LED indicatiors,the red one is for the power,the green one is for the communications with the NCH Pendant controller.

As the picture shows, the wiring section of the controller has Stepper/Servo Ports,Spindle Control Ports,MPG ports,Output and Input Ports,and Power supply Ports,as well as USB ports.

The Inside power 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 structure as below:

The power structure,main power supply input ,MPG module and  Power and USB port share common GND, stepper control module and Input&Output module and Spindle control module share common GND, between the two sector there is photoelectric isolation. Inside of the board, there is GND  as common-, no need to connect external power supply.

 

1) USB Communication Port

 

 

2) Main power supply port

The Power Supply Input voltage is 24VDC, and the power is not less than 20W. The positive and negative connection of the power supply see as the silk printing.

 

3) The Input Ports

The MPG port the DB15 Female terminals next to the USB port. The users need to weld the MPG cables into the DB15 Male terminal,and plug-in to the MPG port of the controller MPG port.

 

 

 As the Picture 2-2 showed,Inputs ports has already defined.The Users can use them as E-stop,Probe,limited/Home functions and so on.The ports is a common negative interface,which can be connected with a micro switch,a 2 line proximity switch or a NPN type 3 line proximity switch.All the ports are isolated.And the internal structure is as following Picture 2-3.

And the E-stop,Micro switch,2 line proximity switch connection methods refered to Picture 2-4.

3 lines Proximity Switch connection method as following Picture 2-6 shows. Brown cable connect with 12V,Black cable connect channel, blue cable connect with GND1.

3 lines proximity switch only NPN type is avaiable for the NCH02.

 

4) The Output Ports

As the Picture 2-8 shows,the interface is an open-ground interface,which can be absorbed not more than 50mA current.The relay with a absorption current of no more than 50mA can be driven directly. If it's more than 50mA, and it is recommended to use a current amplification, for example ULN2803 chip.

5) The MPG Ports

The MPG interface Pin order as following:

6) The Spindle Control Port

The Picture 2-10 showed interface definition is VSO/GND/OT1/OT2.

The VSO is the 0-10V analog output, OT1/OT2 digital signal output, spindle control output interface and spindle inverter connection methods as Picture 2-11. VSO/GND/OT1/OT2 are respectively connected with the inverter AIN1/COM/X1/X2, where AIN1 is the input speed signal;COM is Comman Ground;X1 and X2 are configured to forward and reverse Turning.

7) The Servo/Stepper Port

The following Picture 2-12 shows the definition of Servo/Stepper Ports.There are 5 axis X/Y/Z/A/B,each axis connection is common anode.Output signal voltage is 5V.

DIR is Direction Signal Output;

PUL is Pulse Signal Output.
