1.4 substantival explanation
When operate the NCH02, where will be a lot of English abbreviation, now we list all of
them for your kindly references:
FRO: Feeding adjust: During the operating process, the F value already set, and need to
adjust the current feeding speed, then we can adjust FRO value to realize it.
SRO: Spindle speed adjust: During the operating process, the S value already set, and need
to adjust the current spindle speed, then we can adjust SRO value to realize it :
Current Speed S#=setting S*SRO.
SRJ: speed adjust manually
During the operating process,as the manual speed already set,and we need to adjust the
current speed,and impossible to fix the value during it is working,then we can revise the SRJ
value to realize it.
Current manual speed FS#=Setting manual speed*SRJ.
F:Feedingspeed,the unit is mm/min.For example F=200,means every minute feeding
2000mm.
S: Spindle Speed. Unit is rad/min.For example S=20000,means 20000 revolution/Minute.

Reset: Reset mode.In this mode,it should stop every operation.
“Step”:Manual Step Mode. Every axis candonduct the manual step operation at this mode.
MPG: MPG mode.Every axis can conduct the MPG operation at this mode.
1.5 Noting and Waring
Free from exposure to the electronics without waterproof
function.Please environment as dry as possible. This is the icon.
Wiring warning, the IO input terminal of this equipment support the
equipment with source switch (such as Inductive proximity switch.)When using
such kind of switch, attention please: avoid the +terminal and –terminal of
power supply to connect with GND.This equipment’s analogy quantity
output terminal of spindlecontrolalos have a certain load capacity. Please avoid
this terminal connect with GND.in case that the interior components and parts be
brokendown.
Operation warning, Please do the security measures well when
connecting with the machine tools.The ESTOP, limit and other things must be
perfected.When comes across the emergancy, please press the ESTOPkey at once
or cut off the power directly, thus avoiding the equipment damage and casualty.
High voltage danger, the primary device is 18-32VDC power
supply.Voltage equipment.Pls pay attention to the electricity, safety when conducting
the operation

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.

As the Figure 2-2 showed, Marked No. 3 position is the limited /home input port. they are
the optical isolated Input interface. The input interface is a 11P 3.81 direct insertion terminal
interface, as shown in Figure 2-2 shell silk print, and definition is
GND/INP1/INP2/GND/INP3/INP4/INP5/INP6/INP7/INP8/12V from left to right. Internal
structure reference figure 2-3. The interface 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.
The interface is isolated by the optocoupler, and the internal structure diagram is referred to
figure 2-4. Estop, micro switch, 2 line proximity switch connection method reference figure 2-5.
