1.4 Terminol ogy Definitions
One-keystroke height calibration: In capacitance height measurement
mode, the specific inductive capacity between the capacitance
detection ring and work piece may affect the accuracy of height
measurement due to temperature, pressure, humidity, gas composition
and many other ambient factors. In addition, the serious non-linear
relationship exists between capacitance value and height value.
Microstep has developed the intelligent program of "one-keystroke
height calibration". Only one keystoke will automatically set the
product based on various ambient factors. And within the range of
3-30mm, high accuracy, high precision and high linearity is possible in
display and control.
High speed zone: When the difference between the actual height and the set
height is relatively big, the cutting head will advance towards the set value at the
highest speed in order to reach the set value the soonest; this travel zone is called
high speed zone.
Speed regulating zone: If the cutting head reaches the set value at a
high speed, severe oscillation may be caused and 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 the
dead zone. In this zone, when it is far away from the set value, the
cutting head will move at a higher speed; otherwise, at a lower speed.
The range value of this zone is adjustable. If it is set too big, the
transition is smooth, but the tracking time is too long; if it is set too
small, the tracking is conducted intime, but oscillation may be caused
easy.

调高器说明书
Dead zone: Within a certain height range, the height of the cutting
head will not be adjustable any more. The range is called dead zone. If
the dead-zone range is set too wide, the control precision will be too
low; if it is set too narrow, the cutting head may oscillate up and down
easily. An appropriate value of dead zone will not only guarantee the
control precision but also generate no oscillation.

2. Overview
2.1 Technical Features
Stepper motor instead of conventional DC motor
Model SH-HC30 height controller for flame/plasma cutting torch uses
the proprietary stepper motor control technology of Microstep to
replace the conventional DC motor height control technology, which
makes it faster and smoother in addition to significantly intended
service life.

调高器说明书
The advanced height linear calibration technology makes absolute
height display and control possible when the distance between the
cutting nozzle and work piece is within 3 ~ 30mm in the capacitance
mode under for automatic height control in unit of millimeter and
display accuracy of ± 0.1mm.
Integration of mechanical lifting device and height controller
Detector, controller and drive are highly integrated with adjustable
stroke up to 10cm.
All Digital Technology
Circuit uses SMD technology without any adjustable devices; all
digital control technology ensures high product reliability.
Simple and convenient linearization calibration
The feature of "one-keystroke height calibration" guarantees that in
any circumstances, the user only needs to press one key to calibrate
the absolute height measurement and achieve linear height
measurement.
Applicability in tough environment
The shell uses tamper-proof, waterproof and moisture-proof
aluminum box sealed design, particularly applicable to the severe
environment of high temperature or high electromagnetic interference
from flame cutting or plasma cutting operation.
Var io us interfaces easy to use.
The interface is simple and easy to control. It is suitable for any flame
cutting and plasma cutting CNC system or using alone.
