One key height calibration: when the capacitance height measurement is
adopted, the specific inductive capacity between the capacitance detection ring
and the cutting board may affect the accuracy of height measurement due to
temperature, pressure, humidity, gas composition and many other factors on site.
In addition, the serious non-linear relationship exists between capacitance value
and height value. Our company has developed the intelligent program of "a key
height calibration". You only need to press a key on site, you can set various
factors of change automatically. And within 3-30mm, the display and control of
high accuracy, high precision and high linearity are realized.
High speed zone: When the difference between the actual height and the set
height is bigger, in order to reach the set value at the fastest speed, the cutting
head advances for the set value at the highest speed; this zone is called high
speed zone.
Speed Regulating Zone: When the cutting head reaches the set value at high
speed, severe oscillation may be caused so that the height control is unstable. In
order to achieve a smooth transition, the speed regulating zone is set. This zone
is located between the high-speed zone and dead zone. In this zone, when it is
farther away from the set value, the cutting head moves at higher speed; if not,
at a lower speed. The range value in this zone may be set. When it is too big, the
transition is smooth, but the track time is too long; when it is too small, the
tracking is conducted in time, but oscillation may be caused easily.
Dead zone: When the cutting head is within certain height value, the height of
the cutting head will not be adjusted any more. The range is called dead zone.
When the dead-zone value is too large, the control precision is too low; when it is
too small, the cutting head may oscillate up and down easily. The appropriate
value of dead zone not only can guarantee the control precision but also do not
generate oscillation.

2. Overview
2.1 Technical Features
SH-HC30 Height Controller System Manual
Page4
Stepper motor instead of the traditional DC motor
SH-HC30 flame / plasma cutting torch height controller uses the unique stepper
motor control technology of Start Microstep Company. It subverts the traditional DC
motor height control mode and makes it become fast and smooth, and the life of the
product is increased greatly.
The height of cutting nozzle is displayed directly in the mode of
capacitance height control
The advanced height linear calibration technology makes the cutting nozzle and
cutting board be within 3 ~ 30mm in the automatic height controlling in the
capacitance mode; the absolute height display and control are realized; the unit is
mm. The display accuracy is ± 0.1mm.
Integration of mechanical lifting device and height controller
The integrated design of detector, controller and drive makes the products reach a
high degree of integration; adjusting the stroke: 10Cm.
All Digital Technology
Circuit uses SMD technology without any adjustable devices; all digital control
technology ensures that the product has a high degree of reliability.
Simple and convenient linearization calibration
The function of "One key for height calibration" guarantees that in any circumstances,
the user only needs to press a key, he can calibrate the absolute height
measurement and achieve a linear height measurement.
It can be used in tough environment
The shell uses the sealed, tamper-proof, waterproof and moisture-proof aluminum
box design, particularly applicable to the severe environment of high temperature
and high electromagnetic interference from flame cutting and plasma cutting.
There are various interfaces that are easy to use.
The interface is simple and easy to control, suitable for all flame cutting and plasma
cutting numerical control system, and they can also be used alone.

The voltage divider board may choose the installation position as required, but note: J1 interface is
low-voltage signal; J2 is the high-voltage signal. In order to prevent the interference of
high-pressure and high-frequency signals on the low-voltage signal and improve the stability of the
system, the wire laying of J1 and J2 should be carried out independently.
